Since thousands of years natural products have played a very important role in health care and in prevention of disease. To evaluate the anti-microbial & antidiabetic activities of leaf extracts (chloroform and methanol) of ixora chinensis. A complete literature survey of ixora chinensis revealed that most of the activities reported on leaves and flowers were anti-oxidants, anticancer, anti-microbial activities. For preliminary phytochemical screening of the extracts, we performed tests for alkaloids, carbohydrates, flavanoids, tannins, glycosides, saponins, proteins and steroids. From this study, we can conclusively state that methanol, chloroform leaf extracts of Ixora chinensis has anti-hyperglycemic activity, anti-microbial activity. These results support the use of the plant in folk medicine to manage microbial infections, diabetics and other related diseases.

The present study was aimed to evaluate the nephroprotective activity of ethanolic extract of Carissa carandas Linn. Leaves (EECC) in Gentamicin-induced nephrotoxicity in Wistar albino rats. The renal damage was induced by Gentamicin (80mg/kg body weight, i.p.). Nephroprotective activity was investigated by the administration of EECC at two different doses (100 and 200mg/kg body weight, p.o) for 28 days and by assessing serum parameters, renal oxidative stress markers and histopathological studies. Gentamicin-treated animals showed an increase in serum creatinine, uric acid, urea, and malondialdehyde (MDA) levels and decrease in total protein, reduced glutathione (GSH), and catalase(CAT) compared to normal control animals, which indicates severe nephrotoxicity. Histopathological studies of kidney Gentamicin-treated animals showed extensive acute tubular necrosis and peri-tubular inflammation. Administration of EECC showed a significant improvement (p<0.05) in biochemical and oxidative stress markers compared to the disease group. EECC treated groups showed better histological appearance when compared to the disease group. Ethanolic extract of Carissa carandas Linn. Leaves showed significant nephroprotective activity against gentamicin-induced acute kidney injury.
