Green solvent-based extraction of three Fabaceae species: A potential antioxidant, anti-diabetic, and anti-leishmanial agents. Heliyon 2024; 10:e33668. [PMID: 39044967 PMCID: PMC11263666 DOI: 10.1016/j.heliyon.2024.e33668] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/17/2024] [Revised: 06/21/2024] [Accepted: 06/25/2024] [Indexed: 07/25/2024] Open
Abstract
The Fabaceae is renowned for its diverse range of chemical compounds with significant biological activities, making it a valuable subject for pharmacological studies. The chemical composition and biological activities of three Fabaceae species were investigated using methanol separately and in combination with dimethyl sulfoxide (DMSO) and glycerol for extraction. The results revealed the highest phenolic (49.59 ± 0.38 mg gallic acid equivalent/g), flavonoid (29.16 ± 0.39 mg rutin equivalent/g), and alkaloid (14.23 ± 0.54 mg atropine equivalent/g) contents in the Caesalpinia decapetala methanol extracts. The 2,2-diphenyl-1-picrylhydrazyl (DPPH) scavenging activity and DNA protection activity were the highest (0.88 ± 0.43 μg/mL IC50 and 2149.26 band intensity) in Albizia julibrissin methanol extracts. The α-amylase activity was highest in all methanol extracts (<15 μg/mL IC50 values), while the α-glucosidase inhibition potential was highest (<1 μg/mL IC50 value) in the methanol-glycerol and methanol-DMSO extracts. Pearson coefficient analysis showed a strong positive correlation between the DPPH and α-amylase assays and phytochemicals. Anti-leishmanial activity was observed in decreasing order: A. julibrissin (74.75 %) > C. decapetala (70.86 %) > Indigofera atropurpurea (65.34 %). Gas chromatography-mass spectrometry revealed 33 volatile compounds and, aamong these (Z)-9-octadecenamide was detected in the highest concentration ranging from 21.85 to 38.61 %. Only the methanol extracts of the examined species could be assessed for in vivo studies for immediate applications.

Exploring the excellence of commercial Brahmi products from Thai online markets: Unraveling phytochemical contents, antioxidant properties and DNA damage protection. Heliyon 2024; 10:e24509. [PMID: 38304802 PMCID: PMC10831600 DOI: 10.1016/j.heliyon.2024.e24509] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/17/2023] [Revised: 01/03/2024] [Accepted: 01/10/2024] [Indexed: 02/03/2024] Open
Abstract
Brahmi (Bacopa monnieri (L.) Wettst.) is extensively used as a nutritional supplement in various commercial products as the plant contains abundant phytochemicals and has antioxidant properties. This study assessed the phytochemical contents, antioxidant properties, and DNA damage protection among seven Brahmi products sold through Thai online markets. Results showed that the P6 sample exhibited 3.5-7.5 fold higher bacoside contents than values observed in the other six product samples. The P6 sample also demonstrated the highest TTC, TFC, and TPC compared to the other brands. For antioxidant activity, the samples (P1-P7) displayed high capacity to scavenge DPPH free radicals with slightly significant differences ranging from 78.37 ± 0.25 to 87.21 ± 0.05 at p-value ≤0.01. The P6 sample showed strong protection against H2O2-induced oxidation of DNA strand breakage, indicating highly potent phytochemical compounds with effective free radical scavenging activity, and the ability to prevent DNA damage. The P6 sample showed promise as a valuable ingredient for the development of functional food products. However, further in vivo animal and clinical studies are required to explore the neuroprotective enhancement effects of Brahmi extracts.

Abstract
Myricetin (MC), 3,5,7,3',4',5'-hexahydroxyflavone, chemically belongs to a flavonoid category known to confer antioxidant, antimicrobial, antidiabetic, and neuroprotective effects. MC is known to suppress the generation of Reactive Oxygen Species (ROS), lipid peroxidation (MDA), and inflammatory markers. It has been reported to improve insulin function in the human brain and periphery. Besides this, it modulates several neurochemicals including glutamate, GABA, serotonin, etc. MC has been shown to reduce the expression of the enzyme Mono Amine Oxidase (MAO), which is responsible for the metabolism of monoamines. MC treatment reduces levels of plasma corticosterone and restores hippocampal BDNF (full form) protein in stressed animals. Further, MC has shown its protective effect against amyloid-beta, MPTP, rotenone, 6-OHDA, etc. suggesting its potential role against neurodegenerative disorders. The aim of the present review is to highlight the therapeutic potential of MC in the treatment of several neurological, neuropsychiatric, and neurodegenerative disorders.

Nutraceutical prospects of Houttuynia cordata against the infectious viruses. FOOD BIOSCI 2022; 50:101977. [PMID: 36059903 PMCID: PMC9423882 DOI: 10.1016/j.fbio.2022.101977] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/11/2021] [Revised: 08/04/2022] [Accepted: 08/11/2022] [Indexed: 11/17/2022]
Abstract
The novel enveloped β-coronavirus SARS-CoV-2 (COVID-19) has offered a surprising health challenge all over the world. It develops severe pneumonia leading to acute respiratory distress syndrome (ARDS). Like SARS-COV-2, other encapsulated viruses like HIV, HSV, and influenza have also offered a similar challenge in the past. In this regard, many antiviral drugs are being explored with varying degrees of success to combat the associated pathological conditions. Therefore, upon scientific validation & development, these antiviral phytochemicals can attain a futuristic nutraceutical prospect in managing different encapsulated viruses. Houttuynia cordata (HC) is widely reported for activities such as antioxidant, anti-inflammatory, and antiviral properties. The major antiviral bioactive components of HC include essential oils (methyl n-nonyl ketone, lauryl aldehyde, capryl aldehyde), flavonoids (quercetin, rutin, hyperin, quercitrin, isoquercitrin), and alkaloids (norcepharadione B) & polysaccharides. HC can further be explored as a potential nutraceutical agent in the therapy of encapsulated viruses like HIV, HSV, and influenza. The review listed various conventional and green technologies that are being employed to extract potent phytochemicals with diverse activities from the HC. It was indicated that HC also inhibited molecular targets like 3C-like protease (3CLPRO) and RNA-dependent RNA polymerase (RdRp) of COVID-19 by blocking viral RNA synthesis and replication. Antioxidant and hepatoprotective effects of HC have been evident in impeding complications from marketed drugs during antiviral therapies. The use of HC as a nutraceutical is localized within some parts of Southeast Asia. Further technological advances can establish it as a nutraceutical-based functional food against pathogenic enveloped viruses like COVID 19.

Abstract
BACKGROUND OF THE STUDY: Antioxidants are able to fight against free radicals which then prevent degenerative diseases. Antioxidants can be found in many plants such as water apples.
AIM OF THE STUDY: This research is aimed to determine the antioxidant activity of green honey deli water apple (Syzygium aqueum) leaves, branches, fruits extracts through 2,2-diphenyl-1-picrylhydrazyl (DPPH) and Cupric Reducing Antioxidant Capacity (CUPRAC) methods, total phenolic content (TPC), total flavonoid content (TFC), correlation of TPC and TFC on antioxidant activity, correlation between DPPH and CUPRAC methods, and content of flavonoid compounds found in ethanol fruit extract of green honey deli water apple.
METHODOLOGY: Antioxidant activities were examined by determining ascorbic acid equivalent (AAE) through DPPH and CUPRAC methods. TPC and TFC were determined using UV-vis spectrophotometry. Correlation of TPC and TFC on antioxidant activity and correlation between DPPH and CUPRAC results were analyzed by Pearson’s method. Contents of flavonoid compounds were determined using HPLC.
RESULTS: Antioxidant activities of green honey deli water apple leaves, branches, and fruits extracts according to DPPH and CUPRAC methods were 3.97–354.96 mg AAE/g; 10.46–222.51 mg AAE/g respectively. Ethanol leaves extract had the highest TPC (68.14 ± 1.69 g GAE/100 g) and ethyl acetate leaves extract showed the highest TFC (18.65 ± g QE/100 g). TPC and TFC were found to correlate with the antioxidant activities. DPPH and CUPRAC results also correlated significantly positive.
CONCLUSION: Phenolic and flavonoid compounds had great contribution on antioxidant activities by DPPH and CUPRAC. The two methods exposed linear results. Ethanol fruits extract of green honey deli water apple contained quercetin (0.16%) and kaempferol (0.39%).

Abstract
The African pumpkin (Momordica balsamina) contains bioactive phenolic compounds that may assist in reducing oxidative stress in the human body. The leaves are mainly consumed after boiling in water for a specific time; this hydrothermal process and conditions of the gastrointestinal tract may affect the presence and bioactivity of phenolics either positively or negatively. In this study, the effects of hydrothermal processing (boiling) and in vitro simulated human digestion on the phenolic composition, bioaccessibility and bioactivity in African pumpkin were investigated in comparison with those of spinach (Spinacia oleracea). A high-resolution ultra-performance liquid chromatography, coupled with diode array detection, quadrupole time-of-flight and mass spectrometer (UPLC-DAD-QTOF-MS) was used to profile phenolic metabolites. Metabolites such as 3-caffeoylquinic acid, 5-caffeoylquinic acid, 3,4-dicaffeoylquinic acid, 3,5-dicaffeoylquinic acid and 4,5-dicaffeoylquinic acid were highly concentrated in the boiled vegetable extracts compared to the raw undigested and all digested samples. The majority of African pumpkin and spinach extracts (non-digested and digested) protected Deoxyribonucleic acid (DNA), (mouse fibroblast) L929 and human epithelial colorectal adenocarcinoma (Caco-2) cells from 2,2'-Azobis(2-methylpropionamidine) dihydrochloride (AAPH)-induced oxidative damage. From these results, the consumption of boiled African pumpkin leaves, as well as spinach, could be encouraged, as bioactive metabolites present may reduce oxidative stress in the body.

THE SCIENCE OF THE TOTAL ENVIRONMENT 2021; 779:146431.

Abstract
Radiation can be lethal at high doses, whereas controlled doses are useful in medical applications. Other applications include power generation, agriculture sterilization, nuclear weapons, and archeology. Radiation damages genetic material, which is reflected in genotoxicity and can cause hereditary damage. In the medical field, it is essential to avoid the harmful effects of radiation. Radiation countermeasures and the need for radioprotective agents have been explored in recent years. Considering plants that evolve in radiative conditions, their ability to protect organisms against radiation has been studied and demonstrated. Crude extracts, fractioned extracts, isolated phytocompounds, and plant polysaccharides from various plants have been used in radioprotection studies, and their efficiency has been proven in various in vitro and in vivo experimental models. It is important to identify the mechanism of action to develop a potent plant-based radioprotective agent. To identify this protective mechanism, it is necessary to understand the damage caused by radiation in biological systems. This review intends to discuss the effects of ionizing radiation on biological systems and evaluate plant-based radioprotectants that have tested thus far as well as their mechanism of action in protecting against the toxic effects of radiation. From the review, the mechanism of radioprotection exhibited by the plant-based products could be understood. Meanwhile, we strongly suggest that the potential products identified so far should undergo clinical trials for critically evaluating their effects and for developing an ideal and compatible radioprotectant with no side-effects.

Abstract
Background In Nepal, traditional treatment using medicinal plants is popular. Whereas
medication-overuse headache is, by definition, caused by excessive use of
acute headache medication, we hypothesized that medicinal plants, being
pharmacologically active, were as likely a cause. Methods We used data from a cross-sectional, nationwide population-based study, which
enquired into headache and use of medicinal plants and allopathic
medications. We searched the literature for pharmacodynamic actions of the
medicinal plants. Results Of 2100 participants, 1794 (85.4%) reported headache in the preceding year;
161 (7.7%) reported headache on ≥15 days/month, of whom 28 (17.4%) had used
medicinal plants and 117 (72.7%) allopathic medication(s). Of 46 with
probable medication-overuse headache, 87.0% (40/46) were using allopathic
medication(s) and 13.0% (6/46) medicinal plants, a ratio of 6.7:1, higher
than the overall ratio among those with headache of 4.9:1 (912/185). Of 60
plant species identified, 49 were pharmacodynamically active on the central
nervous system, with various effects of likely relevance in
medication-overuse headache causation. Conclusions MPs are potentially a cause of medication-overuse headache, and not to be
seen as innocent in this regard. Numbers presumptively affected in Nepal are
low but not negligible. This pioneering project provides a starting point
for further research to provide needed guidance on use of medicinal plants
for headache.

Abstract
AIMS To investigate the biological activity of Thai medicinal plant extracts and their active substances on the inhibition of growth and the transcription of colibactin genes of colibactin-producing Escherichia coli, and effect on the pathogenesis from colibactin toxin including transient infections and colibactin-induced DNA damage. METHODS AND RESULTS Among 16 medicinal plants examined, aqueous extracts of Terminalia catappa, Psidium guajava and Sandoricum koetjape demonstrated the growth inhibition against E. coli ATCC 25922, which is known to produce colibactin toxin. These plant extracts contain the active phytochemical compounds, tannin and quercetin, which are able to inhibit the growth of E. coli ATCC 25922. Interestingly, the extracts of T. catappa, P. guajava and S. koetjape, and their compounds tannin and quercetin, protected the eukaryotic epithelial cells of Vero cells and Caco-2 cells from infection and DNA damage by E. coli ATCC 25922. Moreover, these plant extracts and compounds exhibited efficacy to downregulate the expression of five genes (clbA, clbB, clbM, clbN and clbP) that are required for colibactin biosynthesis. CONCLUSIONS The extracts of T. catappa, P. guajava and S. koetjape, and their compounds of tannin and quercetin had ability to inhibit the growth and transcription of colibactin genes of colibactin-producing Escherichia coli. Hence, these plant extracts and compounds could protect the transient infection and DNA damage of the eukaryotic epithelial cells. SIGNIFICANCE AND IMPACT OF THE STUDY This study is the first of its kind to report on the enhancement of the biological properties of T. catappa, P. guajava and S. koetjape, and to support the exogenous compound usage of tannin and quercetin, which may be able to protect against the transient infection and DNA damage of eukaryotic cells from E. coli carrying colibactin toxin.

Abstract
The study was designed to evaluate antigenotoxic effect of methanol Teucrium arduini and Teucrium flavum extracts against mitomycin C (MMC)-induced chromosome and DNA damage in vitro. Cytokinesis-block micronucleus (CBMN) and comet assays were used to investigate effect of plant extracts in different concentrations (125, 250, 500 and 1000 µg/mL) on human peripheral blood lymphocytes (PBLs). The obtained results showed that the all tested concentrations of T. arduini and the highest concentration of T. flavum significantly reduced the MMC-induced micronucleus (MN) frequency in comparison to positive control (only MMC). There were significantly negative correlations between the extracts concentrations and MN frequencies (Pearson, r = -0.905, p = 0.0001 for T. arduini; r = -0.861, p = 0.0001 for T. flavum). The extracts of both plants further lowered the MMC-decreased nuclear division index (NDI) in a dose dependent-manner (Pearson, r = -0.837, p = 0.001 for T. arduini; r = -0.598, p = 0.040 for T. flavum), but significantly only in the highest concentration (1000 µg/mL). Comet assay showed that extracts reduced MMC-increased genetic damage index (GDI), significantly in the concentrations of 500 and 1000 μg/mL, in comparison with positive control. Based on our results, it can be concluded that methanol T. arduini and T. flavum extracts possess protective proapoptotic and antigenotoxic effect which is indication of their medicinal relevance and use in treatment.

Abstract
The aim of present study was to access the antioxidant and ameliorative efficacy of Wendlandia heynei stem bark's crude methanol extract (WHBM) against bisphenol A (BPA)-induced hepatotoxicity in the rat moel. WHBM and its derived fractions exhibited promising activity for the scavenging of DPPH, hydroxyl and nitrite radicals, iron chelation, and for the inhibition of β-carotene oxidation. The administration of BPA to Sprague Dawley rats (25 mg kg-1) for 28 days resulted in an elevated (p < 0.01) level of aspartate transaminase, alanine transaminase, alkaline phosphatase, and globulin, and at the same time a decrease (p < 0.01) in the level of total protein and albumin in the serum of the rats. In hepatic samples, the levels of catalase, peroxidase, superoxide dismutase, glutathione-S-transferase, and reduced glutathione were decreased (p < 0.05), whereas thiobarbituric acid reactive substances, hydrogen peroxide, and the nitrite content were increased (p < 0.05) with BPA treatment to the rats. The administration of WHBM to BPA-intoxicated rats restored the altered levels of these parameters toward the control animals. Histopathological alterations of the hepatic tissues induced with BPA were restored with WHBM co-treatment to the rats. HPLC-DAD analysis ensured the occurrence of rutin, catechin, and caffeic acid in WHBM and WHBE. The results of this study suggested that the presence of phenolics and flavonoids in W. heynei bark might be responsible for it exhibiting antioxidant potential during the in vitro and in vivo studies and hence it has potential to be used as a therapeutic agent against oxidative stress associated diseases.

Abstract
Fagonia indica is a traditionally used phytomedicine to cure hepatic ailments. However, efficient validation of its hepatoprotective effect and molecular mechanisms involved are not yet well established. Therefore, the present study was designed to evaluate the hepatoprotective activity of Fagonia indica and to understand the molecular mechanisms involved in the reversal of hepatic injury. The liver injury mouse model was established by thioacetamide followed by oral administration of plant extract. Serum biochemical and histological analyses were performed to assess the level of hepatic injury. Expression analysis of proinflammatory, hepatic, and immune regulatory genes was performed with RT-PCR. Results of serological and histological analyses described the restoration of normal liver function and architecture in mice treated with plant extract. In addition, altered expression of proinflammatory (IL-1β, IL-6, TNF-α, and TGF-β) and hepatic (krt-18 and albumin) markers further strengthens the liver injury reversal effects of Fagonia indica. Furthermore, a significant expression regulation of innate immunity components such as toll-like receptors 4 and 9 and MyD-88 was observed suggesting an immune regulatory role of the plant in curing liver injury. In conclusion, the current study not only proposes Fagonia indica, a strong hepatoprotective candidate, but also recommends an immune regulatory toll-like receptor pathway as an important therapeutic target in liver diseases.

Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Houttuynia cordata Thunb. (Family: Saururaceae) is an herbaceous perennial plant that grows in moist and shady places. The plant is well known among the people of diverse cultures across Japan, Korea, China and North-East India for its medicinal properties. Traditionally the plant is used for its various beneficial properties against inflammation, pneumonia, severe acute respiratory syndrome, muscular sprain, stomach ulcer etc. Oxidative stress and inflammation were found to be linked with most of the diseases in recent times. Many ancient texts from Chinese Traditional Medicine, Ayurveda and Siddha, and Japanese Traditional medicine have documented the efficacy of H. cordata against oxidative stress and inflammation. AIM OF THE STUDY This review aims to provide up-to-date and comprehensive information on the efficacy of H. cordata extracts as well as its bioactive compounds both in vitro and in vivo, against oxidative stress and inflammation MATERIALS AND METHODS: Relevant information on H. cordata against oxidative stress and inflammation were collected from the established scientific databases such as NCBI, Web of Science, ScienceDirect, Elsevier, and Springer. Additionally, a few books and magazines were also consulted to get the important information. RESULTS Herbal medicines or plant products were traditionally being used for treating the oxidative stress and inflammation related diseases in diverse communities across the world. Scientifically, H. cordata has shown to target several signaling pathways and found to effectively reduce the oxidative stress and inflammation. Phyto-constituents such as afzelin, hyperoside and quercitrin have shown to reduce inflammation both in vitro and in vivo models. These molecules were also shown to have strong antioxidant properties both in vivo and in vitro models. CONCLUSIONS H. cordata extracts and its bioactive molecules were shown to have both anti-inflammatory and anti-oxidative properties. As both in vitro and in vivo studies were shown that H. cordata did not have any toxicity on the various model systems used, future clinical studies will hopefully make an impact on the future direction of treating inflammation-related diseases.

Abstract
Objective Natural antioxidant products are gaining popularity as treatments for various pathological liver injuries. Musanga cecropioides (Urticaceae) leaf extract is used in ethnomedicine for the management of jaundice and other hepatic ailments in Ibibio, Nigeria. This study evaluated the hepatoprotective and antioxidant effects of M. cecropioides hydromethanolic leaf (MCHL) extract against carbon tetrachloride (CCl4)-induced hepatotoxicity in rats. Methods Liver damage was induced by administering CCl4 dissolved in liquid paraffin (2 mL/kg bw 1:1 intraperitoneally) after pretreatment with MCHL extract for 7 days. Thereafter, acute hepatotoxicity was evaluated in 36 Wistar rats divided into six groups (A–F) of six animals each. Group A served as the negative control; B received CCl4 1 mL/kg only; C–E received 70.7, 141.4, and 282.8 mg/kg MCHL extract, respectively; and F received silymarin 100 mg/kg daily for 7 days by oral gavage. After 48 h, the rats were sacrificed, and samples obtained from them were assayed for histological and biochemical biomarkers of hepatotoxicity. Results The MCHL extracts significantly (p < 0.001–0.05) reduced the increase in aspartate aminotransferase (AST), alanine aminotransferase (ALT), alkaline phosphatase (ALP), conjugated bilirubin (CBIL), and total bilirubin (TBIL) levels induced by CCl4 intoxication. There was no significant alteration in haematological indices or weight following administration of the MCHL extracts. Histopathological examinations revealed mitotic bodies in the 141.4 mg/kg MCHL extract-treated rats, an indication of tissue repair processes. Conclusion The MCHL extract has a dose-specific hepatoprotective effect; hence, the utilisation of this extract for the management of hepatitis requires caution.

Abstract
The aim of this study was to understand the antioxidant metabolic changes of peach (cvs. 'Royal Glory', 'Red Haven' and 'Sun Cloud') and nectarine fruits (cv. 'Big Top') exposed to different combinations of low-temperature storage (0, 2, 4 weeks storage at 0 °C, 90% R.H.) and additional ripening at room temperature (1, 3 and 5 d, shelf life, 20 °C) with an array of analytical, biochemical and molecular approaches. Initially, harvested fruit of the examined cultivars were segregated non-destructively at advanced and less pronounced maturity stages and qualitative traits, physiological parameters, phytochemical composition and antioxidant capacity were determined. 'Big Top' and 'Royal Glory' fruits were characterized by slower softening rate and less pronounced ripening-related alterations. The coupling of HPLC fingerprints, consisted of 7 phenolic compounds (chlorogenic, neochlorogenic acid, catechin, epicatechin, rutin, quecetin-3-O-glucoside, procyanidin B1) and spectrophotometric methods disclosed a great impact of genotype on peach bioactive composition, with 'Sun Cloud' generally displaying the highest contents. Maturity stage at harvest did not seem to affect fruit phenolic composition and no general guidelines for the impact of cold storage and shelf-life on individual phenolic compounds can be extrapolated. Subsequently, fruit of less pronounced maturity at harvest were used for further molecular analysis. 'Sun Cloud' was proven efficient in protecting plasmid pBR322 DNA against ROO attack throughout the experimental period and against HO attack after 2 and 4 weeks of cold storage. Interestingly, a general down-regulation of key genes implicated in the antioxidant apparatus with the prolongation of storage period was recorded; this was more evident for CAT, cAPX, Cu/ZnSOD2, perAPX3 and GPX8 genes. Higher antioxidant capacity of 'Sun Cloud' fruit could potentially be linked with compounds other than enzymatic antioxidants that further regulate peach fruit ripening.

Abstract
BACKGROUND Evaluation of Euphorbia dracunculoides of family Euphorbiaceae during previous studies had established the in vitro antioxidant and in vivo anti-inflammatory activities. The plant is used by the local communities of Pakistan for various disorders including rheumatism and edema. In this investigation we have evaluated the hepatoprotective effects against CCl4 induced toxicity in rat. METHODS Dry powder of the aerial parts of E. dracunculoides was extracted with 95% methanol to get the extract (EDME). To investigate the hepatoprotective effects of EDME the Sprague-Dawley male rats were divided in to 8 groups with 6 rats in each. Group I and II were the normal and vehicle treated while the Groups III-VI were injected intraperitoneally with 1 ml of CCl4 (30% in olive oil). Rats of Group IV were orally administered with silymarin (50 mg/kg) while the Group V and VI with 200 mg/kg and 400 mg/kg of EDME, respectively. Animals of Group VII (200 mg/kg) and VIII (400 mg/kg) were treated with EDME alone. The treatments were given thrice a week for 4 weeks. Effects of EDME were evaluated for the protective effects against oxidative stress and genotoxicity induced with CCl4 in liver of rat. RESULTS Analysis of serum indicated significant (p < 0.05) rise in the level of aspartate transaminase (AST), alanine transaminase (ALT), alkaline phosphatase (ALP) and globulin whereas decrease was recorded for the total protein and albumin in CCl4 treated rats. In liver tissues the activity level of catalase (CAT), peroxidase (POD), superoxide dismutase (SOD), glutathione-S-transferase (GST), glutathione (GSH) was decreased while the level of lipid peroxides; thiobarbituric acid reactant substances (TBARS), nitrite and hydrogen peroxide increased in CCl4 treated rats as compared to the control group. Histopathological injuries and DNA damages were recorded in liver of rat with CCl4 treatment. However, co-administration of EDME, dose dependently, ameliorated the CCl4-induced hepatic toxicity in these parameters. CONCLUSIONS These results suggested that the phyto-constituents of EDME were able to ameliorate the oxidative stress induced with CCl4 and can be a useful therapeutic agent for oxidative stress related disorders.

Abstract
OBJECTIVE Achillea is a traditional medicinal herb which contains different phenol and flavonoid compounds that are responsible for Achillea pharmacological effects. We aimed to determine phenol and flavonoid contents, besides antioxidant activities of different extracts from Achillea eriophoraa (A. eriophora) DC. and Achillea biebersteinii (A. biebersteinii) Afan. (endemic species in Iran) and to investigate their effects on human cells. MATERIALS AND METHODS Achillea extracts, were prepared by maceration and shaking methods, from different parts (aerial parts, stem, leaves and inflorescence) of two species using methanol and ethanol as solvents. Total phenol and flavonoid contents were measured by spectrophotometry, and antioxidant activities of the extracts were determined by DPPH radical scavenging, BCB and TBARS assays. Cytotoxicity and antioxidant activities of the extracts were investigated in Human Foreskin Fibroblast (HFF3) cells using MTT, comet and H2O2 assays. RESULTS Methanol extracts of A. biebersteinii prepared from leaves and inflorescence by maceration method exhibited maximum phenol (1657.58 ± 36.45 mg GAE/100 g DW) and flavonoid (264.00 ± 62.16 mg QUE/100 g DW) contents. Leaf methanol extract showed significantly higher antioxidant activity (0.0276 ± 0.003, 0.16 ± 0.016 and 13.96 ± 0.26 mg/ml for DPPH, BCB and TBARS IC50s, respectively) than those of the other extracts. Leaf extract of A. biebersteinii was not cytotoxic even at the highest examined dose (512 µg/ml) and inhibited cell toxicity induced by H2O2 (98% viability for the cells pretreated with plant extract in the presence of H2O2). Comet assay also confirmed high DNA protective activity of leaf extracts. CONCLUSION Achillea extracts possess remarkable antioxidant activity, and could be good natural alternatives to synthetic antioxidants in pharmaceutical and food industries.

Abstract
For thousands of years, the plant-based natural products have been a source of curative agents for various ailments. Butea monosperma (Fabaceae) has an important place in Indian traditional system of medicine for curing number of disorders. The present study deals with evaluation of hepatoprotective properties of ethyl acetate fraction (Beac) from B. monosperma bark in rat model. In preliminary antioxidant studies, Beac demonstrated pronounced superoxide scavenging (IC50 88.85μg/ml) and anti-lipid peroxidation (IC50 131.66μg/ml) potential. In animal studies, Beac showed protective effect against thioacetamide-induced pathophysiology in liver of male Wistar rats. The levels of different parameters related to hepatic functions were altered by thioacetamide treatment (300mg/g bw) in rats. The pre-treatment of rats with Beac (50, 100 and 200mg/kg bw) was able to normalize the biochemical markers viz. serum bilirubin, SGOT, SGPT, albumin and ALP along with liver antioxidative molecules viz. SOD, CAT, GSH and GR. Results of histopathological and colorimetric studies revealed that Beac treatment also restored the markers of fibrosis i.e. collagen and hydroxyproline towards normal level. Beac considerably inhibited thioacetamide-induced expression of p-PI3K, p-Akt and p-mTOR in hepatocytes as revealed from immunohistochemical studies. This finding is the first evidence of inhibitory action of B. monosperma bark on these pro-carcinogenic proteins. HRMS analysis revealed the presence of quercetin, buteaspermin B and ononin in Beac fraction of Butea monosperma. From the results, it can be concluded that B. monosperma bark is a rich source of phytochemicals with in vitro and in vivo protective activities which deserves further mechanistic studies for its use as a hepatoprotective agent in the prevention of hepatic inflammation and its related malignancies.

Abstract
BACKGROUND Hydrogen peroxide is continuously generated in living cells through metabolic pathways and serves as a source of reactive oxygen species. Beyond the threshold level, it damages cells and causes several human disorders, including cancer. METHODS Effect of isolated 3-O-methyl quercetin and kaempferol on H2O2 induced cytotoxicity, ROS formation, plasma membrane damage, loss of mitochondrial membrane potential, DNA damage was evaluated in normal liver and lung cells. The RT-PCR analysis used to determine Nrf 2 gene expression. Calorimetric ELISA was used to determine Nrf2 and p-38 levels. Expression of SOD and catalase was analyzed by Western blot analysis. RESULTS The present study isolated 3-O-methyl quercetin and kaempferol from the stem bark. They protected normal lung and liver cells from H2O2 induced cytotoxicity, ROS formation, membrane damage and DNA damage. Pre-treatment with 3-O-methyl quercetin and kaempferol caused translocation of Nrf2 from cytosol to nucleus. It also increased expression of p-p38, Nrf2, SOD and catalase in H2O2 treated lung and liver cells. CONCLUSION The flavonoids isolated from S. anacardium significantly reduced H2O2 induced stress and increased expression of Nrf2, catalase and superoxide dismutase-2 indicating cytoprotective nature of 3-O-methylquercetin and kaempferol.

Abstract
Myricetin (Myc) is one of the most important flavonoids in diet due to its abundance in foods with the highest antioxidant activity. The antioxidant activity of Myc was studied in cell-free and cell-based systems to evaluate the ROS protection efficiency of Myc. The studies were based on the assessment of reducing power of Myc according to ferric ion reduction and intracellular ROS level measurement by assaying the cellular fluorescence intensity using dichlorodihydrofluorescein (DCF) probe as an indicator for ROS in cells. Moreover, the antitoxic capability of Myc was assessed using MTT method. Data indicated that intracellular ROS are highly toxic and applying low concentration of Myc not only inhibited cellular ROS production but also was accompanying with the protection of cells against the highly toxic and the lethal effects of peroxide compounds. Because of strong correlation between cellular ROS and their cell toxic properties, the higher antioxidant potency of Myc in cell medium resulted in effectively blocking intracellular ROS and protecting cell death. This property is achieved by the help of high polar solubility and cell membrane permeability of Myc.

Abstract
Dietary total antioxidant capacity (DTAC) seems to be associated with reducing risk of diseases. However, data about the influence of the DTAC on oxidative stress parameters are scarce. The aim of this study was to estimate the DTAC and its influence on plasma total antioxidant capacity (PTAC), and damage to lipids, proteins and DNA in healthy women. It was found a positive correlation between DTAC and PTAC in young and healthy subjects, where presumably the endogenous defenses are fully functional. DTAC and PTAC were positively correlated with the intake of known antioxidants, including vitamin C and polyphenols. The DTAC exhibited a negative correlation with lipid oxidative damage, while PTAC showed a negative correlation with DNA damage. This data contributes to better understanding of the recommended dietary antioxidant intake for promoting health.

Abstract
The aim of this study was to investigate the antioxidant activity of orange (Citrus auranthium) flesh (OF) and peel (OP) extracted with acetone, ethanol, and methanol. Antioxidant potential was examined by measuring total phenolic content (TPC), 2,2-diphenyl-1-picrylhydrazyl (DPPH) radical scavenging activity (RSA), total radical-trapping anti-oxidant potential (TRAP), oxygen radical absorbance capacity (ORAC), and cellular antioxidant activity (CAA). The comet assay was used to determine the protective effects of OF and OP against H2O2-induced DNA damage. TPC was highest in the acetone extracts of OF and OP. DPPH RSA was also higher in the acetone extracts than in the ethanol extracts. The DPPH RSA was highest in the acetone extracts of OF. The TRAP and ORAC values of the all extracts increased in a dose-dependent manner. In the TRAP assay, the acetone extracts of OF and OP had the lowest IC50 values. In the CAA assay, the methanol and acetone extracts of OP had the lowest IC50 values. All of the samples protected against H2O2-induced DNA damage in human leukocytes, as measured by the comet assay, but the acetone extracts of OP had the strongest effect. These results suggest that acetone is the best solvent for the extraction of antioxidant compounds from OF and OP. Furthermore, the high antioxidant activity of OP, which is a by-product of orange processing, suggests that it can be used in nutraceutical and functional foods.

Abstract
The objectives of this study were to identify the antioxidants and antioxidant axtivity in 27 of Taiwan's indigenous vegetables. Lycium chinense (Lc), Lactuca indica (Li), and Perilla ocymoides (Po) contained abundant quercetin (Que), while Artemisia lactiflora (Al) and Gynura bicolor (Gb) were rich in morin and kaempferol, respectively. Additionally, Nymphoides cristata (Nc) and Sechium edule (Se)-yellow had significantly higher levels of myricetin (Myr) than other tested samples. Cyanidin (Cyan) and malvidin (Mal) were abundant in Gb, Abelmoschus esculentus Moench (Abe), Po, Anisogonium esculentum (Retz.) Presl (Ane), Ipomoea batatas (Ib)-purple, and Hemerocallis fulva (Hf)-bright orange. Relatively high levels of Trolox equivalent antioxidant capacity (TEAC), oxygen radical absorption capacity (ORAC), and 1,1-diphenyl-2-picryl-hydrazyl (DPPH) radical scavenger were generated from extracts of Toona sinensis (Ts) and Po. Significant and positive correlations between antioxidant activity and polyphenols, anthocyanidins, Que, Myr, and morin were observed, indicating that these phytochemicals were some of the main components responsible for the antioxidant activity of tested plants. The much higher antioxidant activity of Po, Ts, and Ib (purple leaf) may be related to their higher Cyan, Que, and polyphenol content.

Abstract
Hyperlipidemia and many other metabolic diseases are related to oxidative stress. Centella asiatica is a traditional Chinese medicine whose antioxidant effect in vitro has been reported. We are interested in whether it possesses this effect in vivo and hence modulates lipid metabolism. Therefore, experiments were carried out on mice and golden hamsters regarding its antioxidant and hypolipidemic effect. We observed that a fraction (CAF3) of the ethanol extract (CAE) of Centella asiatica had a cholesterol decrease of 79% and a triglyceride decrease of 95% in acute mice model, so CAF3 was further investigated in high-fat-fed hamster model. It was shown that CAF3 increased SOD and GSH-Px activities and decreased MDA level, and it also improved TC, TG, LDL-C, HDL-C, AST, and ALT levels. L-CAT and SR-BI gene expression in hamsters were increased. Taken together, our data suggest that the CAF3 fraction of Centella asiatica has antioxidant and hypolipidemic properties.

Abstract
OBJECTIVE Ferula szowitsiana has been widely used for medicinal purposes around the world. The anti-oxidant effect of F. szowitsiana had been proved. The current study aims to determine the protective effects of galbanic acid, a sesquiterpene coumarin from F. szowitsiana, against hydrogen peroxide (H2O2) - induced oxidative DNA damage in human lymphocytes. MATERIALS AND METHODS Human lymphocytes were incubated with H2O2 (0, 25, 50, 100, and 200 µM), galbanic acid (200 and 400 µM) and a combination of galbanic acid (200 and 400 µM) and H2O2 (25 µM) at 4 C for 30 minutes. Solvents of galbanic acid without H2O2 were used as negative controls. RESULTS The findings of this study demonstrated that H2O2 exposure leads to a significant concentration-dependent increase in DNA damage. Galbanic acid did not cause DNA damage compared with the control cells. Data showed that galbanic acid does not have a protective effect against H2O2-induced oxidative DNA damage in human lymphocytes. CONCLUSION According to the results, it is concluded that the capability of F. szowitsiana in reducing reactive oxygen species and the anti-inflammatory property of its methanolic extract may be due to its other ingredients.

Abstract
Effects of mulberry leaf-related extracts (MLREs) on hydrogen peroxide-induced DNA damage in human lymphocytes and on inflammatory signaling pathways in human aortic endothelial cells (HAECs) were studied. The tested MLREs were rich in flavonols, especially bombyx faces tea (BT) in quercetin and kaempferol. Polyphenols, flavonoids, and anthocyanidin also abounded in BT. The best trolox equivalent antioxidant capacity (TEAC) was generated from the acidic methanolic extracts of BT. Acidic methanolic and water extracts of mulberry leaf tea (MT), mulberry leaf (M), and BT significantly inhibited DNA oxidative damage to lymphocytes based on the comet assay as compared to the H2O2-treated group. TNF- α -induced monocyte-endothelial cell adhesion was significantly suppressed by MLREs. Additionally, nuclear factor kappa B (NF- κ B) expression was significantly reduced by BT and MT. Significant reductions were also observed in both NF- κ B and activator protein (AP)-1 DNA binding by MLREs. Significant increases in peroxisome proliferator-activated receptor (PPAR) α and γ DNA binding by MLREs were also detected in M and MT extracts, but no evidence for PPAR α DNA binding in 50 μ g/mL MT extract was found. Apparently, MLREs can provide distinct cytoprotective mechanisms that may contribute to its putative beneficial effects on suppressing endothelial responses to cytokines during inflammation.
