The study was undertaken to evaluate the antioxidant potential of Plumbago zeylanica L. in streptozotocin (STZ) diabetic rats. The ethanolic extract of ischolar_main of P. zeylanica L. at doses of 100 mg, 200 mg/kg p.o. for 21 days resulted in significant reduction in plasma TBARS and a significant elevation in plasma reduced glutathione (GSH), ascorbic acid. It is concluded that these results suggest that the ethanolic extract of ischolar_main of P. zeylanica L. possess a strong antioxidant effect in diabetic rats.Keywords

A simple and inexpensive method was developed with high performance liquid chromatography with PDA detection for determination of entacapone and its related impurities are (N, N diethyl cyano acetamide), (3,4 Dihydroxy 5-Nitro benzaldehyde) and (2-Z)-2-Cyano-3-(3,4-Dihydroxy-5-nitrophenyl)N,N-diethyl-2- propenamide. The chromatographic separations were achieved on (250×4.6 mm), 5.0 μm make: Phenomenex Luna column employing Acetonitrile: HPLC Water in the ratio of 50:50 (v/v) as mobile phase with isocratic at flow rate 0.9 mL/min was chosen. Three impurities were eluted within 15 minutes. The column temperature was maintained at 30°C and a detector wavelength of 210 nm was employed. The method was successfully validated by establishing System Suitability, Specificity, Linearity, Accuracy, limit of detection and Limit of quantification.Keywords

The increasing demand for water has brought immense pressure on groundwater resources in the regions where groundwater is prime source. In the present study an attempt has been made to evaluate groundwater potential index (GWPI) for understanding the hydro geological condition of Kallar Watershed, South India. Vertical Electrical Sounding (VES) was carried out at 17 locations within and around the study area. The interpretation of the data obtained from the VES revealed that three non-aquifer geo-electrical layers overlie the un-fractured basement. The first layer has an average thickness of about 0.5 m and resistivity of 83 Ohm-m. The thickness of the second layer is about 0.7 m and resistivity of 438 Ohm-m. The third layer is about 3.4 m thick and has resistivity of about 63 Ohm-m. Aquifer resistivity and thickness interpreted from VES data is used to generate the corresponding thematic maps. Weights are assigned to different ranges of resistivity and thickness values based on their position on geological map. Finally the weighted maps are integrated using a GIS based aggregation method to evaluate the groundwater potential index of the area.Keywords
