<p><em>Onopordum acanthium</em> (Scotch thistle) belong to Asteraceae (Compositae). <em>O. acanthium</em> is a flowering biennial plant native to Europe and Western Asia with coarse spiny leaves 20-50 cm in width with conspicuous and spiny-winged stems. We have previously reported pro-apoptotic and cytotoxic effect of <em>Onopordum acanthium</em> crude extract against glioblastoma U-373 cells. The present study was designed to evaluate the cytotoxicity, antioxidant, xanthine oxidase inhibition, anti-inflammatory, analgesic, antipyretic activity of butanolic extract of <em>Onopordum acanthium</em>. Cytotoxicity of different solvent (methanolic, butanol, chloroform and petroleum ether) extract studied by brine shrimp lethality bioassay, total flavonoid and phenolic, antioxidant, xanthine oxidase inhibition activity was studied by <em>in-vitro</em> whereas anti- inflammation studied by carrageenan-induced paw edema model, antipyretic with 20 % brew yeast injection induced pyretic model, analgesic with 1 % acetic acid induced analgesic model investigated in <em>in-vivo </em><em>in</em> wistar rats. Good antioxidant activity was found with IC50 = 134.4 µg/ml with considerable amount of total phenolic and flavonoid content. Xanthine oxidase inhibition effect was weak with IC50 = 572.9 µg/ml. Oral administration of <em>O. Acanthium</em> butanolic extract (OA) showed minimum lethality of brine shrimp nauplii henceforth OA butanolic phases was selected for further <em>in-vivo</em> studies. OA 200 and 400 mg/kg body weight decreased the oedema by 37.78 % and 40.52 %, respectively; standard aspirin 100 mg/kg decreased 42.62 % at 5th hour of Carrageenan injection.  OA 200 and 400 mg/kg significantly decreased acetic acid-induced abdominal writhes when compared to standard aspirin. OA have shown dose and time dependent decrease in body temperature in yeast induced pyrexia, comparable to standard, aspirin. The present results demonstrate that OA has notable anti-inflammatory, antipyretic, analgesic activity related to presence of phenolic compounds as from literature it has been demonstrated that isolated compounds from aerial parts of <em>Onopordum acanthium </em>had strong activity in <em>in-vitro</em> assay.  </p>

Purpurogallin is a plant phenol that is sometimes added as an oxidation retardant to fats–oils or to certain fuels or lubricants. However, it was unknown if purpurogallin is cytoprotective. Here we examined this issue, both in isolated hepatocytes and in vivo. From 0.5 to 2.0 mM, purpurogallin prolongs survival of rat hepatocytes substantially against oxyradicals generated with xanthine oxidase and hypoxanthine. The protection was dose dependent and surpassed that given by such antioxidants as ascorbate, mannitol, superoxide dismutase, catalase, and Trolox, when each was examined at or near its optimal concentration in the same system. When 1.5,3, and 6 μmol of purpurogallin in saline were infused into rats with postischemic livers shortly before reperfusion, the mean hepatic salvages were 42, 76, and 86%, respectively. Such salvage effects would rank purpurogallin highly among the hepatoprotectors known. Over the range of 31 to 500 μM, purpurogallin inhibited the rate of O2 consumption in the xanthine oxidase reaction by ~90%, which was 2- to several-fold higher than the inhibition elicited by allopurinol over the same concentrations. Thus, purpurogallin is an effective natural hepatoprotector that may operate partly or principally as an inhibitor of xanthine oxidase.Key words: purpurogallin, hepato-protection, xanthine oxidase inhibition.

Hyperuricemia is a metabolic disorder with characteristic elevated serum uric acid. Recently, several plant-based medicines are being used for the treatment of hyperuricemia. The study aimed to find the hypouricemic potential of Berberis vulgaris in in-vitro and in-vivo study models. In i n-vitro studies, xanthine oxidase inhibition assay was performed to evaluate IC50 value and capsule absorbance of the drug, respectively. For in-vivo experiment, the study comprised 15 groups of rats. In-vitro results revealed that significant xanthine oxidase inhibition was shown by Berberis vulgaris with an IC50 value of 272.73±.3 μg/mL. Similarly, oral administration of Berberis vulgaris with dosages of 250 and 500 mg/kg decreased serum and liver uric acid levels significantly in a dose- and time-dependent manner in oxonate-induced hyperuricemic rats. Furthermore, 3-day and 7-day administration of Berberis vulgaris showed more potential compared to 1-day administrations. The present study indicated marked hypouricemic effects of Berberis vulgaris in rats. Due to caveat of the small sample size, a firm assumption of the hypouricemic effect of Berberis vulgaris cannot be made. However, extensive study is needed to find out the exact molecular mechanism involved and to translate its effects into clinical trials for the further validation of the results.

Objective: Dietary curcumin and capsaicin are well known for their health beneficial potencies. The current study was done to assess the anti-inflammatory activity of curcumin, capsaicin and their combination by employing in vitro and in vivo models.Methods: We investigated the protective effect of curcumin, capsaicin and their combination using in vitro heat induced human red blood cell (HRBC) membrane stabilisation, in vivo 3% agar induced leukocyte mobilisation and acetic acid induced vascular permeability assay.Results: Curcumin, capsaicin and their combination exhibited concentration dependent protective effect against heat-induced HRBC membrane destabilisation, while combined curcumin and capsaicin restored 87.0±0.64 % membrane stability and it is found to be better than curcumin, capsaicin and diclofenac sodium (75.0±0.25. 72±0.9 and 80.0±0.31 %) protective effect. In agar suspension induced leukocyte mobilization assay, the combined curcumin and capsaicin had shown 39.5±1.58 % of inhibition compared to individual curcumin and capsaicin, which showed moderate inhibition of 16.0±3.14 and 21.6±2.17 % respectively. Besides, the combined curcumin and capsaicin had shown highly significant inhibition of acetic acid-induced vascular permeability in rats (62.0±3.14 %), whereas individual curcumin and capsaicin showed moderate inhibition of vascular permeability with 36.0±2.41 and 43.0±1.92 % respectively.Conclusion: This study demonstrates the significant anti-inflammatory property of combined curcumin and capsaicin at half of the individual concentration of curcumin and capsaicin.

Dendropanax morbifera H. Levis a medicinal plant native to South Korea, East Asia, and South America. Among some 75 species, one species grows in Korea. In previous studies, D. morbifera extracts with anti-oxidant, anti-inflammatory, anti-complementary and anti-cancer activities were reported. The present study aims to investigate optimization of extraction and evaluation of anti-hyperuricemic effects of D. morbifera leaf and the phytochemicals contained therein. Ethanol and hexane extract were found to display the best xanthine oxidase inhibition among six types of solvent and water extract. The antioxidant effect of the ethanol extract was superior to that of the hexane extract. The DPPH radical scavenging effect of the ethanol and hexane extracts were 81.52 ± 1.57% and 2.69 ± 0.16. The reducing power of the ethanol and hexane extracts were 9.71 ± 0.15 and 0.89 ± 0.01 mg/g equivalent of gallic acid. Total phenols of the ethanol and hexane extracts were 6.53 ± 0.16 and 0.63 ± 0.001 mg/g equivalent of gallic acid. In addition, we compared the two marker compounds from D. morbifera, chlorogenic acid and rutin, which were determined in the ethanol extract at 0.80 ± 0.03% and 0.52 ± 0.01%, respectively. We found that the ethanol extracts showed better xanthine oxidase inhibition than hexane extracts. Especially, ethanol extracts showed higher antioxidant activity than hexane extracts. Based on these results, we selected the ethanol extract as an effective xanthine oxidase inhibitor and confirmed whether ethanol extracts showed xanthine oxidase inhibition in animal experiments. The in vivo mouse study demonstrated that ethanol extract of D. morbifera leaf at the dose of 300 mg/kg could inhibit blood/hepatic xanthine oxidase activity and this result shows that the xanthine oxidase inhibitory activity in vitro is reproduced in vivo. The present study showed that ethanol extract was optimal xanthine oxidase inhibitor which can be applied to prevent diseases related to hyperuricemia.

Objective: The current study was carried out to investigate the xanthine oxidase inhibitory, antihyperuricemic, anti-inflammatory, and antinociception activity of α-lipoic acid (LA) in gouty model of rats.Methods: Enzyme assay was done using bovine milk xanthine oxidase (XO). The XO inhibitory activity in vitro was performed using different doses of α-LA, and the degree of XO inhibition was expressed as IC50. The antihyperuricemic activity of α-LA was tested in the potassium oxonate-induced hyperuricemic rats for 7 consecutive days of oral treatment of 10, 25, and 50 mg/kg doses. The anti-inflammatory activity was achieved through monosodium urate crystal-induced inflammation hind paw model in mice. The antinociception effects of α-LA were explored using both of writhings induced by acetic acid test and hot plate test.Results: The study results revealed that the α-LA has a potent activity of XO inhibition with IC50 = 2.93 μg/mL. Furthermore, these results showed that all doses of α-LA were able to significant reduce of each the following: Serum uric acid levels in the hyperuricemic rats, hind paw thickness of mice at all periods of time assessment, and writhings number in the acetic acid-induced writhing test, while, the same doses significantly increased the reaction latency in mice at hot plate test.Conclusion: The α-LA showed a significant effect on the evaluated models, and therefore it may be a promising agent for the treatment of gout since it possesses XO inhibitory, antihyperuricemic, anti-inflammatory, and antinociception activity.

Background.Libidibia ferrea(L. ferrea)is found throughout the northeastern region of Brazil, where it has been used in folk medicine with beneficial effects on many inflammatory disorders.Purpose. This study investigated the phytochemical composition of the crude extract and fractions ofL. ferreafruit and evaluated its anti-inflammatory and antinociceptive activitiesin vivoand effect on cell viabilityin vitro.Methods. Characterization of polyphenols present in crude extract (CE), hydroalcoholic fractions of 20-80% ethanol (CE20, CE40, CE60, and CE80), aqueous fraction (AqF), and ethyl acetate (EAF) fractions ofL. ferreafruit was performed by chromatographic analysis.Anti-inflammatory activity was evaluated by using a carrageenan-induced peritonitis model submitted to a leukocyte migration assay and myeloperoxidase activity (MPO) analysis. Total glutathione and malondialdehyde (MDA) levels were assessed to evaluate the oxidative stress level. Antinociceptive activity was evaluated by acetic acid-induced abdominal writhing and hot plate test.In vitrocell viability was determined by using MTT assay in a mouse embryonic fibroblast cell line (3T3 cells).Results. Chromatography revealed the presence of ellagic acid content in EAF (3.06), CE (2.96), and CE40 (2.89). Gallic acid was found in EAF (12.03), CE 20 (4.43), and CE (3.99).L. ferreacrude extract and all fractions significantly reduced leukocyte migration and MPO activity (p<0.001).L. ferreaantioxidant effect was observed through high levels of total glutathione and reduction of MDA levels (p<0.001). Acetic acid-induced nociception was significantly inhibited after administration ofL. ferreacrude extract and all fractions (p<0.001). Crude extract and all fractions significantly increased the viability of the 3T3 cell line (p<0.05).Conclusions. The appropriate extraction procedure preserves the chemical components ofL. ferreafruit, such as gallic acid and ellargic acid. Crude extract and fractions ofL. ferreafruit exhibited anti-inflammatory, antioxidant, antinociceptive activitiesin vivoand enhanced cell viabilityin vitro.
