Objective: To compare the method of estimation of Gymnemic acids by HPLC and Gravimetry. Material and methods: Gymnema sylvestres leaves, Glass ware for Gravimetry analysis, Vacuum Tray driers (VTD), an Isocratic, Reversed phase (RP) HPLC procedure has been adopted using a mixture of Acetonitrile (23%) and 0.1% Orthophosphoric acid as mobile phase, C18 column as stationary phase and UV detector. Results: The comparative method shows high resolution, accuracy and reproducibility. Conclusion: The Comparative method shows that HPLC method of analysis is better than Gravimetry estimation of Gymnemic acids in Gymnema sylvestres.Keywords

Objective: To study the effect of Terminalia chebula on serum lipids in hyperlipidemic rats. Methods: The hypolipidemic action of T. chebula has been studied in normal rats and in atherogenic (cholesterol containing) diet induced hyperlipidemic albino rats. Results: In atherogenic diet induced hyperlipidemic model, the rats receiving alcoholic extract of immature (IMF), mature (MF) fruits and ethyl acetate soluble fraction (immature fruits) of T. chebula treatment showed marked reduction in total cholesterol (TC) (p<0.05), total triglyceride (TG) (p<0.001), total protein (TP) (p<0.001) and elevation in high density lipoprotein cholesterol (HDL-C) (p<0.001). In normocholesterolemic model, the feeding of ethanolic extract (immature fruits) lowered the levels of TC, TG, TP and increased level of HDL-C. Conclusions: The ethanolic extract and ethyl acetate fraction were found to possess significant hypolipidemic activity. The most active extract of T. chebula is ethyl acetate fraction of immature fruits, which was able to bring high serum lipid to normal level. The present study brings forth the efficacy of < as a hypolipidemic agent.Keywords

This research was taken up to investigate the antioxidant activity of leaves of Tephrosia purpurea. The in vitro antioxidant activity of ethanolic extract of leaves of Tephrosia purpurea was investigated by DPPH free radical scavenging, and nitric oxide scavenging methods. The ethanol extract showed good antioxidant activity in these above methods. This activity may be due to the presence of flavanoids.Keywords
