Revista Cienfica, FCV-LUZ / Vol. XXXV UNIVERSIDAD DEL ZULIA Serbiluz Sistema de Servicios Bibliotecarios y de Información Biblioteca Digital Repositorio Académico INTRODUCTION Oxidave stress is a proven biological phenomenon that takes place as a consequence of an overproducon of reacve oxygen species (ROS) in either cells or ssues. This leads to macromolecular damage from oxidaon and the disrupon of gene regulaon, ulmately resulng in cell death [1 , 2 , 3]. At controlled levels, ROS act as signaling molecules that mediate plant responses to bioc and environmental stresses by modulang physiological funcons and parcipang in diverse metabolic pathways [4 ,5]. However, their accumulaon may lead to the formaon of pro-inflammatory molecules, contribung to inflammaon and ssue injury, which can ulmately result in chronic inflammatory diseases [6 , 7]. In order to counteract these harmful consequences, anoxidants of natural origin, in parcular those derived from medicinal plants with bioacve compounds capable of modulang oxidave stress and inflammaon, have received considerable interest from scholars in recent years [8 , 9]. In fact, for a long me in the history of medical pracces, plants have been used as remedies for many diseases, with secondary metabolites playing a vital role as precursors for numerous drugs and pharmaceucals in modern medicine [10 , 11]. Under this group, Zingiber officinale (Z. officinale), generally known as ginger in English or “gingembre” in French [12 , 13]. In Asian countries such as India, was used as a spice for over two thousand years and as a flavoring agent throughout anquity. It is a seasonal, herbaceous, erect plant with a pseudo-stem growing to a height of 0.3 to 1 meter. Its leaves have hairy peoles with lengths of 2 to 4 mm, with leaves themselves measuring 15 to 23 cm in length and 8 to 15 mm in width. Its morphological characteriscs include roots, stems, rhizomes, leaves, and flowers. Its rhizomes can last for long in the soil and display the capability to produce new shoot growth to compensate for shed leaves and stems [14]. Its rhizome is flat with a pale-yellow interior and is strongly fibrous. Its roots grow from the juncon at the lower side of the rhizome, with shoots developing at the top. Variees of ginger are different in shape and have differences in taste as well [14]. Ginger (Zingiber officinale, Roscoe) has bioacve compounds such as shogaol, gingerol, and flavonoids, making it a natural source of various secondary compounds and an anoxidant-rich plant (FIG. 1), [15 , 16]. It has tradionally been used in the prevenon and treatment of stomach-upseng dilemmas such as dyspepsia, intesnal- derived ailments, and various types of food poisoning [17]. Ginger has also been proven useful in combang arthric diseases, aiding in transport-related complaints, and reducing pregnancy-related voming. Raw ginger is richest in enzymes that aid digeson and has tradionally been used as an andote for burned skin [16 , 18 , 19]. FIGURE 1. Zingiber officinale rhizome The increase in body warmth has further been linked to strengthened circulaon and a possible reducon in blood pressure [20]. Zingiberene is primarily idenfied as the main component found in Z. officinale essenal oil (19.71 %), accompanied by (+)-β-cedrene, farnesene, α-curcumene, and β-elemene in larger amounts [21]. The major acve and stable phenolic compounds found in the acve component of ginger, such as shogaols, paradols, zingerone and gingerols, have been known to exhibit anoxidant, an-angiogenic, an-atheroscleroc, and ancancer acvies as suggested by previous studies [22 , 23]. Taking into consideraon the aforemenoned factors, the aim of this present study is to evaluate the in vitro anoxidant, in vivo an-inflammatory acvity, as well as the total phenolic compound content of Z. officinale. MATERIALS AND METHODS Plant material Dried rhizomes of Z. officinale were purchased from a local market and ground to a fine light-yellow powder. The powder was prepared immediately before extracon. Extracon procedure With a few minor adjustments, the plant’s ethanolic extract was prepared [24]. In short, 85 % ethanol was used to extract the dried powder of Z. officinale for 72 hours (h) at room temperature. Aſter filtering the resultant mixture, the filtrate was evaporated (Buchi rotavap R-205, Switzerland), at 45 °C. The pharmacological characteristics of the dried extract were examined. Total phenolic contents The total phenolic content was measured using a modified Folin-Ciocalteu (FC) assay, as described previously [25]. In summary, a 0.1 mL aliquot of plant extract or standard was mixed with a 0.5 mL aliquot of FC reagent, which was previously diluted 1:10. Aſter a 4-min reacon me, a 0.4 mL aliquot of a 7.5 % sodium carbonate soluon was added. Absorbance was then measured (Shimadzu UV1800 spectrophotometer, Germany), at 765 nm, and total phenolics were calculated as gallic acid (GA) equivalents (FIG. 2). 2 of 9

UNIVERSIDAD DEL ZULIA Serbiluz Sistema de Servicios Bibliotecarios y de Información Biblioteca Digital Repositorio Académico FIGURE 2. Standard curve for gallic acid. Total flavonoid contents Total flavonoid content in each of the plant extracts was determined using the aluminum chloride (AlCl 3 ) colorimetric assay [26]. A detailed descripon of this method involves mixing 1 mL of extract with 1 mL of 2 % AlCl₃ in methanol, which is then allowed for 10 minutes (min) of incubaon, with measurements conducted at 430 nm to calculate in terms of quercen equivalent, (FIG. 3). FIGURE 3. Standards curve for quercen. Anoxidant potenals 1-diphenyl-2-picrylhydrazyl radical scavenging assay The scavenging capacity of extract was determined using the 1-diphenyl-2-picrylhydrazyl (DPPH) assay, according to the method of Burits and Bucar [27]. Briefly, a mixture of each extract (0.05 mL) and a soluon of DPPH (1.25 mL, containing 0.004 % DPPH in methanol) was used, with butylated hydroxytoluene (BHT) serving as the posive control. Aſter 30 min of incubaon, the absorbance was measured at 517 nm. The scavenging acvity was esmated from the relevant formula. It expresses further the anoxidant acvity as IC₅₀ (mg/mL), where : is the absorbance of the control and : is the absorbance of the sample β-carotene bleaching assay Anoxidant acvies were evaluated using the ability to suppress the accumulaon of conjugated dienes and volale oxidaon products of linoleic acid, based on the method of Dapkevicius et al. [28]. Briefly, a mixture of 0.5 mg of β-carotene in 1 mL of Chloroform was prepared, to which were added 200 mg of Tween-40 and 0.025 mL of Linoleic acid. Oxygen-saturated dislled water (100 mL) was added aſter complete evaporaon of the Chloroform at 40 °C to achieve the emulsion. To each test tube pre-loaded with 0.350 mL of sample soluon (2 mg/mL), 2.5 mL of the aforemenoned emulsion was added. All were kept at room temperature in the darkness. Posive controls used were GA and BHT. Absorbances were recorded at 490 nm at intervals of 0, 1, 2, 3, 4, 6, 12, and 24 h. Relave anoxidant acvies (A %) was esmated using the following formula: where and represent the absorbances of the control and sample at , respecvely. Reducing power assay The previously published approach was used to determine the extract’s reducing power [29]. Briefly, 0.1 mL volumes of the methanol-facilitated extracts, K 3 Fe(CN) 6 , and 0.2 M phosphate buffer soluon, pH 6.6, were allowed to react. Aſter a 20- min incubaon period at 50 °C, the reacons were stopped through the addion of 0.25 mL volumes of 1 % trichloroacec acid. About 0.25 mL volumes were mixed with 0.25 mL volumes of dislled water and 0.5 mL volumes of 0.1 % FeCl 3 soluon. The absorbance was measured (Shimadzu UV1800 spectrophotometer, Germany) at 700 nm. An-inflammatory capacies Xylene induced ear edema As outlined by the process designed by Aa and Alkohafi [30], the Xylene-induced edema of the ears was performed using Xylene. The study involved four groups with six mice (Mus musculus) each. Edema was induced by the topical applicaon of 40 μL Xylene to the outer part of the ears. The first group was the standard treatment and was given 100 mg/kg of indomethacin. The second group was the negave control and given NaCl soluon (0.9 %) as treatment, while the third and the fourth groups received the plant extract with a dose of 200 and 400 mg/kg, respecvely. The ears were measured using the digital caliper (caliper to DIN 862, Germany) before and two hours aſter the inducon of the inflammaon. The percentage inhibion of the inflammaon or the edema was measured using the formula: Where D Control is the difference in edema thickness in the control group, and D Treated is the difference in edema thickness for the treated group. 3 of 9

Before the treatment, the mice had free access to drinking water. The animals were made to fast for 12 h, aſter which the test subjects received compounds orally via gavage. Acute inflammaon was elicited by the subplantar injecon of 0.02 mL of 1 % w/v carrageenan in normal saline into the right hind paw of the test subjects, thirty min following treatment, as done in the research study conducted by Belay and Makonnen [31] on the model menoned above. The measurement of the paw thickness for each test subject involved using the digital caliper. The percentage of paw swelling was esmated as follow: D0 is the paw thickness, and Dt is the paw thickness aſter carrageenan injecon at a given me point. Stascal analysis GraphPad Prism, ver. 6.01 for Windows, was applied for stascal analysis. Values are esmated as mean ± SD. For the anoxidant test, we used t-test cause wa have only two samples, the rest we used anova because we have more then two samples. RESULTS AND DISCUSSION Yield, total phenolic and flavonoid contents The focus of this study is the determinaon of the phytochemical constuon of a hydroethanolic extract (HEE) of the rhizome of Z. officinale, specifically in terms of the total phenolic and flavonoid contents using the spectrophotometric method. The esmate of yield in relaon to the total powder weight (100 g) of plant, shows that the HEE present a 7.4 % of yield (TABLE I). The total phenolic and flavonoid contents of the sample were 203.12 ± 06.95 µg GAE/mg extract and 11.62 ± 0.00 µg QE/mg extract, respecvely. In Comparison, Lukia et al. [32] reported a phenolic content of 155.78 µg GAE/mg extract, indicang a higher phenolic content in the current study. The results are presented in TABLE I. As for flavonoid content, the results obtained are similar to the findings of Bekkouch et al. [33]. Previous invesgaons have revealed that Z. officinale is rich with various phenolic compounds, including 6-paradol, 6-shogaol, 6-gingerol, methyl 6-gingerol, 8-gingerol, 5-gingerol, 1-dehydro-6-gingerol and 10-gingerol, [34]. In general, Variaons in total phenolic content (TPC) and total flavonoid content (TFC) values in plant extracts may be aributed to the presence of non-flavonoid polyphenols like phenolic acids and tannins. Rhizomes of Z. officinale contain major bioacve compounds gingerols and shogaols; they are polyphenols but not flavonoids. This may be a plausible reason for the higher values of TPC over TFC in the HEE. Variaons in the type of solvents used for the extracon process may affect the polyphenol and flavonoid contents. Hydroethanolic solvents tend to increase the recovery of various polyphenolic compounds. TABLE I Yield, total polyphenols and flavonoids contents of Z. officinale extract.

The disparity in concentraons of 8-gingerol and 10-gingerol may also be aributed to variaons in extracon and stability. These compounds are known to be the main bioacve markers for ginger and are believed to be responsible for its anoxidant and an-inflammatory properes. Thus, the quantave analysis of these compounds is essenal for standardizaon, quality, and efficacy of ginger-based pharmaceucals for uniform therapeuc effects. Anoxidant acvity 2,2-Diphenyl-1-picrylhydrazyl free radical scavenging assay In vitro anoxidant tests are used extensively as a first step to screen plant extracts for the ability to scavenge free radicals. Among these tests, the DPPH radical-scavenging assay is the most frequently used technique for its simplicity, speed, and reproducibility. The DPPH free radical has been shown to be a stable nitrogen-centered radicals, which changes color to yellow upon reducon by an anoxidant, hence perming quantave measure of the radical-scavenging ability. The amount of extract needed to scavenge 50 % of the DPPH radicals has been shown to serve as an indicator for the potency of the anoxidave effect. The extract showed a clear dose-dependent ability to scavenge DPPH radicals, with an IC 50 of 0.12 ± 0.00 mg/mL. The results are presented in TABLE II. While this level was significantly lower than the standard anoxidant: BHT, (P < 0.0001), which had an IC 50 of 0.01 ± 0.00 mg/mL, the extract sll proved its capacity to neutralize free radicals. The IC 50 value observed is considerably lower than that reported by [35] (IC₅₀ = 4.25 mg/mL). TABLE II Anoxidant acvity of hydroethanolic Z. officinale extract Anoxidant acvity/Inhibion concentraon (IC 50 ) Extract/ standards DPPH radical scavenging Reducing power GEE 26.06 ± 0.00 *** 39.43 ± 0.00 *** BHT 87.26 ± 0.00 ND Vitamin C ND 21. 91 ± 0.48 GEE: ginger ethanol extract. BHT: butylated hydroxytoluene The HEE of Z. officinale rhizomes had a strong concentraon- dependent ability to scavenge the DPPH radicals. The higher the concentraon of the extract, the higher the ability to scavenge the radicals, thereby indicang a strong ability to donate hydrogen or electron density to scavenge the radicals. The low IC₅₀ value obtained depicts that only a low concentraon of the 4 of 9
In vitro and in vivo invesgaons of Zingiber officinale rhizome / Derafa et. al. UNIVERSIDAD DEL ZULIA Serbiluz Sistema de Servicios Bibliotecarios y de Información Biblioteca Digital Repositorio Académico extracts is required to scavenge 50 % of the DPPH radicals, thus signifying a high ability to scavenge free radicals. This remarkable acvity is likely linked to the extract’s high phenolic content, consistent with previous studies highlighng the pivotal role of phenolic compounds in free radical neutralizaon [35]. This strong anoxidave property can be aributed to the high phenolic content presented in the extract. Phenolics, such as the gingerols present in Z. officinale, are known to tame the free radicals by the phenomenon of resonance. This is because the phenolics prevent the oxidaon reacon by the free radicals. This concentraon-dependent property also confirms the presence of the bioacve compounds, as the concentraon increases the amount of the anoxidave molecules that can interact with the DPPH molecules [36]. Taken together, the high DPPH scavenging capacity shown by the HEE of the Z. officinale rhizome reported in the present study supports the tradional use and provides further raonale to the reported findings demonstrang the anoxidant role of ginger phenolic compounds. Such anoxidant acvity may be shown to be responsible for the an-inflammatory acvity exhibited by the HEE. Reducing power assay The extract exhibited a strong reducing power, with an IC 50 of 0.013 ± 0.00 mg/ml, a result comparable to that of the standard BHT, measured at 0.0012 ± 0.00 mg/ml. This suggests that the extract has a strong ability to donate electrons and can effecvely reduce Fe 3+ to Fe 2+ . Comparave study on different ginger plant parts noted that ethanolic extracts excel in electron transfer-based anoxidant assays, such as ferric reducing power, which highlights the contribuon of phenolic compounds to reducing capacity [37 , 38]. Overall, the DPPH, β-carotene-linoleic, and reducing power results show that Zingiber officinale’s ethanolic extract has potent anoxidant acvity. This effect largely stems from its high levels of phenolic and flavonoid compounds such as shogaol, gingerol, zingerone, and paradol. These compounds work synergiscally to reduce the producon of ROS. Ginger helps boost glutathione levels, stops lipid peroxidaon, inhibits the generaon of nitric oxide, scavenges hydroxyl radicals, promotes the acvity of anoxidant enzymes like superoxide dismutase and catalase, and lowers the expression of inducible nitric oxide synthase, further supporng its role as a powerful anoxidant [39]. β-carotene/linoleic acid bleaching assay In the β-carotene–linoleic acid assay, anoxidants inhibit the formaon of volale compounds and conjugated diene hydroperoxides that result from linoleic acid oxidaon [40]. The ethanolic extract of ginger showed a strong result in prevenng lipid peroxidaon, with 82 % inhibion. This result is comparable with BHT, which reached an inhibion of 99, and is significantly higher than GA with 46 % inhibion (FIG. 4). FIGURE 4. The inhibion percentage of Z. officinale ethanolic extract was evaluated by β-carotene-linoleic acid assay. Samples were analyzed aſter 24 hours, Posive controls used were GA and BHT. Data are presented as mean ± SD (n = 3). *P < 0.05 stascally significant, ***P < 0.0001. GEE: Z. officinale ethanol extract. The β-carotene-linoleic acid assay is one common method that has been widely accepted for the determinaon of the anoxidant acvity of plant extracts using their ability to block the oxidaon of lipids. In the β-carotene-linoleic acid assay, the linoleic acid undergoes an oxidave breakdown when heated in the presence of oxygen, forming free radicals and conjugated diene hydroperoxides. The highly unsaturated molecules of β-carotene are aacked by the reacve oxidaon product. The results obtained align with previous studies reporng that ethanolic plant extracts protect ssues against lipid peroxidaon in vivo and effecvely scavenge reacve oxygen species in lipid rich environments [41 , 42]. Xylene induced ear edema Inflammaon serves as the body’s defense system to get rid of infecons, burns, and toxins, as well as to iniate the healing process. According to Ayustaningwarno et al. [43], it results in discomfort, swelling, heat, redness, and disrupons of physiological processes. Unchecked acute inflammaon develops into chronic inflammaon, which leads to chronic inflammatory disorders [44]. This leads to the considerable producon of inflammatory mediators, including NO, PGE2, TNF- , IL-1, IL-6, and COX-2, which are linked to the pathophysiology of ssue damage [45]. Many inflammatory diseases are characterized by excessive acvity of macrophages and the formaon of free radicals that cause ssue destrucon [46]. Topical administraon of xylene induces acute edema in mice’s ears, which serves as a widely accepted model for evaluang an-inflammatory acvity [6 , 47]. Xylene is known to trigger the release of inflammatory mediators, leading to vasodilaon and increased vascular permeability, resulng in edema formaon [47]. In the present study, ear edema induced using xylene and treated with ethanolic extract of Z. officinale at doses of 200 and 400 mg/kg resulted in significant edema reducon measured at 57 and 54 %, respecvely (FIG. 5). These results are comparable 5 of 9
Revista Cienfica, FCV-LUZ / Vol. XXXV UNIVERSIDAD DEL ZULIA Serbiluz Sistema de Servicios Bibliotecarios y de Información Biblioteca Digital Repositorio Académico with those obtained using the well-known an-inflammatory drug, indomethacin, with 76% reducon of edema. Zhang et al. [20] also demonstrated the an-inflammatory efficiency of Z. Officinale’s oils compared to ibuprofen. According to previous invesgaons, the beneficial effects are largely aributed to bioacve compounds like 6-shogaol, which play a role in modulang inflammatory mediators such as COX-2, INOS, NF- κB, and MAPK signaling pathways [48]. FIGURE 5. Effect of Z. officinale ethanolic extract on xylene-induced ear edema in mice compared to indomethacin at 100 mg/kg. GEE: Ethanol extract, values represent means ± SEM (n=6), ns: not significant. Carrageenan-induced acute inflammaon in mice Carrageenan, a linear sulfated polysaccharide, induces local edema and serves as a standard model for evaluang an-inflammatory acvity [49]. Early-phase mediators of carrageenan-induced edema include bradykinin, histamine, and endothelial-derived nitric oxide, which increase vascular permeability through specific signaling pathways [50 , 51]. In this study, Z. officinale extracts effecvely inhibited carrageenan- induced paw edema during both the first and second phases of inflammaon. The result of the an-edematous acvity of the oral administraon of Z. officinale extract in carrageenan-induced paw edema in mice is given in FIG.6. The subplantar injecon of carrageenan in the negave control group increased paw edema progressively in the first hour post-injecon (31.61 %), aaining the maximum at the fourth hour (54.26 %). Treatment of the animals with diclofenac resulted in a significant reducon in paw edema two h aſter sub plantar injecon of carrageenan (27.16 %), with the effect persisng for up to 4 h (20.23 %), compared to the control group. Oral administraon of the ethanolic extract appears to be more effecve at 400 mg/kg, compared to the 200 mg/kg dose. FIGURE 6. Inhibion Kinecs of GE extract vs. Control Standards Over 4 hours. GE: ginger hydroethanolic extract The an-edematous effect may be mediated by inhibion of prostaglandin producon and antagonism of serotonin, consistent with previous reports [52]. Addionally, the presence of polyphenols and gingerols in the extract might help reduce inflammaon by inhibing cyclooxygenase and lipoxygenase pathways, reducing neutrophil and macrophage acvaon, and ulmately leading to limitaons in monocyte and leukocyte migraon [34 , 53]. It is important to point out the clear dose- dependent effect where higher concentraons lead to a greater reducon in pro-inflammatory cytokines and an increase in anoxidant capacies, which further supports the role of secondary metabolites in the observed an-inflammatory effects [54]. The an-inflammatory acvity and the capacity to stop the release of cytokines that cause inflammaon are also part of the Z. officinale extract [55]. The plant has been known to have pharmacological acvity, especially an-inflammatory acvity and anoxidant acvity. The major bioacve compounds found in ginger are gingerols, shogaols, and paradols, which play a vital role in the pharmacological acvity of ginger. The an- inflammatory acvity of ginger can be explained by its capacity to inhibit key enzymes such as cyclooxygenase-2 (COX-2) and lipoxygenase (LOX) that are involved in the inflammatory process. This helps to alleviate the inflammaon process in diseases such as rheumatoid arthris and osteoarthris [56 , 57]. Hence, the role of plant-based phytochemicals, which have ethnopharmacological potenal, is to act as the main source of medicine for early drug discovery and to establish the structure for structure-acvity relaonship studies. Phytochemicals are potent sources of anoxidants, and this property helps in the reducon of various health risks associated with oxidave damage. This is due to the presence of various secondary metabolites such as alkaloids, glycosides, flavonoids, and saponins in the plant, and this property of scavenging free radicals helps in amelioraon [58 , 59]. CONCLUSION The study invesgates the phytochemical contents, the anoxidant capacies and the in vivo an-inflammatory acvity of Z. officinale HEE. The collecve outcome revealed ta notable 6 of 9

UNIVERSIDAD DEL ZULIA Serbiluz Sistema de Servicios Bibliotecarios y de Información Biblioteca Digital Repositorio Académico anoxidant and an-inflammatory capacies when compared to the reference compounds used in the study. While the synthec compounds demonstrated a stronger potency, the consistency of the acvity displayed by the extract cannot be overlooked. This highlights the unique advantage of the plant, acng on mulple pathways simultaneously, in contrast to the one- component pharmacology of the synthec compounds. This mul-target approach posions ginger as a valuable addion to complementary and prevenve medicine for dealing with issues related to oxidave stress and inflammaon. However, the findings call for more rigorous studies, emphasizing the requirement of the extract being biochemically standardized, the characterizaon of the acve compounds, and the mechanisc evaluaon at the molecular level. Future research should be directed towards conducng in vivo bioavailability studies to assess the absorpon of these compounds, as well as their clinical efficacy for long-term use. This strategy should aid in the scienfic validaon of Zingiber officinale based preparaons, parcularly for the treatment of oxidave stress-related diseases.
