Most of the synthetic drugs used at present as analgesic and anti-inflammatory agents cause many side effects and toxic effects. Many medicines of plant origin with analgesic and anti-inflammatory activity have been used since long time without adverse effects. The purpose of the study was to explore the anti-pyretic and anti-oxidant activity of fruits of Garcinia pedunculata. The fruit of G. pedunculata was collected from Shillong, Meghalaya and extraction is done by using methanol as a solvent. The methanol extract shows the presence of carbohydrate, glycoside, alkaloids, phenol and flavonoids. Acute anti-pyretic activity for the extract was investigated in pyrexia rat. Temperature level was determined after 1hours, 4 hours, 8 hours and 12 hours after giving the extract dose of 100mg/kg and 200mg/kg body weight, and it was found to produce a significant reduce in fever. DPPH radical scavenging activity (In-vitro anti-oxidant activity of G. pedunculata) of methanolic extract shows 38.31 as IC50 (µg/ml) whereas Ascorbic acid as standard in the same concentration shows 34.81 IC50 (µg/ml). The obtained result justified the traditional use of G. pedunculata as anti-pyretic and antioxidant purpose.

Objective: The objective of this study was to determine the anti-inflammatory activity of methanol extract of Niebuhria apetala and its possible mechanism of action. Methods: Methanol extract of Niebuhria apetala leaf (NAL) was assessed for its anti-inflammatory activity by in vitro methods. Using albumin denaturation assay, proteinase inhibitory activity, membrane stabilization, and antilipoxygenase activity at different concentrations, in vitro anti-inflammatory activity was estimated. The standard drug used for this purpose was aspirin. Results: Methanol extract NAL at a concentration range of 100–500 μg/ml significant (p<0.01) protects the heat-induced protein denaturation. At the concentration of 500 mg/ml, NAL showed significant (p<0.01) inhibition of protease inhibitory action. Heat-induced hemolysis of erythrocyte, hypotonicity-induced hemolysis, and lipooxygenase activity were significant (p<0.01) inhibited at the concentration of 500 μg/ml. Conclusion: Finally, the present study indicates that methanol extract of Niebuhria apetala can be a potential source of anti-inflammatory agent.

Background: Our previous findings demonstrated that in vitro supplementation of polyphenols, extracted from seeds of red grape (Nero di Troia cultivar), to peripheral lymphomonocytes from patients affected by allergic contact dermatitis (ACD) to nickel (Ni) could reduce release of pro-inflammatory cytokines and nitric oxide (NO), while increasing levels of interleukin (IL)-10, an anti-inflammatory cytokine. Objective: To assess whether an intervention with oral administration of polyphenols leads to a reduction of peripheral biomarkers in ACD patients. Method: At T0, 25 patients affected by ACD to Ni were orally administered with 300 mg polyphenols prodie extracted from seeds of red grape (Nero di Troia cultivar) (NATUR-OX®) for 3 months (T1). Other 25 patients affected by ACD to Ni received placebo only for the same period of time. Serum biomarkers were analyzed at T0 and T1. In both groups seven drop outs were recorded. Result: At T1 in comparison to T0, in treated patients, values of IFN-γ, IL-4, IL-17, PTX3 and NO decreased, while IL-10 levels increased when compared with T0 values. Conversely, in placebo-treated patients no modifications of biomarkers were evaluated at T1. Conclusion: Present laboratory data rely on the anti-oxidant, anti-inflammatory and anti-allergic properties of polyphenols.
