In conclusion, our findings suggest that flavonoid fraction (MAF) and luteolin (0.5% w/w) may have potential benefit in enhancing wound healing in diabetic condition, possibly due to free-radical scavenging activity of plant.

The results of present study suggests that the aqueous extract of P. acidus leaves has significant hepatoprotective activity on APAP and TAA induced hepatotoxicity, which might be associate with its high phenolic and flavonoid content and antioxidant properties.

The ethanolic extract of the fruits of Momordica dioica was studied for its protective and curative effect against gentamicin-induced acute renal injury in albino rats of both sexes. Gentamicin intoxicated group showed significant increase in blood urea (69.48 +/- 4.34) and serum creatinine (3.017 +/- 0.208) from normal levels 33.72 +/- 1.92 and 0.818 +/- 0.073, respectively, in control group. In the preventive regimen, the extract at dose levels of 200 mg kg(-1) showed significant reduction in the elevated blood urea (47.93 +/- 2.46) and serum creatinine (2.067 +/- 0.1745), respectively. This treatment normalised the histopathological changes compared to the intoxicated group. In the curative regimen at 200 mg kg(-1) blood urea was found to be 48.21 +/- 2.36 and serum creatinine level was 2.050 +/- 0.183, which revealed significant curative effect. In vivo antioxidant and free radial scavenging activities were also determined. The maximum free radical scavenging activity with ethanolic extract was the basis of selection of this extract for in vivo study. Reduced glutathione (GSH) level was significantly (p < 0.05) increased in the extract treated groups whereas malondialdehyde (MDA) was reduced significantly (p < 0.05). High content of flavonoids and phenolic compounds was found in ethanolic extract, which may be responsible for free radical activity. The findings suggest that the ethanol extract of Momordica dioica seeds possesses marked nephroprotective and curative activities without any toxicity due to its antioxidant activity and could offer a promising role in the treatment of acute renal injury caused by nephrotoxin-like gentamicin.

The present study was undertaken to investigate the effect of ethanolic extract (ext.), ethyl acetate (EA) fractions and precipitate fraction (ppt.) of total ethanolic extract of Zizyphus xylopyrus on depression in rats. In the present study, the antidepressant effect of Zizyphus xylopyrus was examined using two behavioral models, the forced swimming test (FST) in rats and tail suspension test (TST) in rats.Ethanolic extract when administered at an acute dose of 50 mg/kg of body weight (P<0.01) reduced the immobility time by 10 and 15 seconds as compared to the immobility time of control in both the screening models. Similarly EA reduced latter by 30 and 35 secs. The ppt. fraction showed the best activity, reducing the immobility time by 50 and 60 secs. in both the tests. These results showed that after standard i.e. Imipramine HCl (30 mg/kg), the ppt. fraction is potent amongst all the studied drugs The present study clearly demonstrated that Zizyphus xylopyrus exerts an antidepressant effect in these two behavioral models. It may be due to present of flavonoids.
