Objective: To evaluate the preliminary phytochemical analysis and in vitro antioxidant activity, anti-diabetic effect of ethanolic seed extract of Acacia catechu against the alpha amylase and alpha glucosidase digestive enzymes in the pancreas and small intestine. Methods: Preliminary phytochemical analysis was done by adopting the method of Evans. Antioxidant assay is performed by DPPH, ABTS and FRAP assay, Anti diabetic activity was determined by modified method of miller, the extract at different concentrations was tested for mammalian alpha amylase and alpha glucosidase enzyme inhibitory assay under the controlled experimental conditions and subjected to determination of absorbance. Results: The present study reveals the presence of few secondary metabolites and the extract exhibits potent Antioxidant activity and a concentration dependent inhibition of Alpha amylase and Alpha glucosidase. Conclusion: From the present study it can be concluded that ethanolic seed extract of Acacia catechu possessed marked in vitro antioxidant and anti-diabetic effect. The effect was plausibly due to the presence of phenolic contents of Acacia catechu.

The effect of the ethanolic extract of the leaves of capparis sepiaria Linn was studied against carbon tetrachloride induced hepatotoxicity in Wister rats. Significant hepatoprotective effects were obtained in liver damage induced by carbon tetrachloride as evident from decreased serum levels of glutamate pyruvate transaminase (SGPT),glutamate oxaloacetate transaminase (SGOT), alkaline phosphatase (ALP) and bilirubin (SB) in the capparis sepiaria (CS) treated groups (100,200 mg/kg), compared to the intoxicated controls. The hepatoprotective effect was further confirmed by histopathalogical studies of the liver, which showed improved architecture, absence of nuclear pycnosis, hepatocyte congestion and necrosis, when compared with the liver of the toxin group of animals. capparis sepiaria (CS) extract also showed significant free radical scavenging activity In Vitro. Thus the present study provides a scientific rationale for the traditional use of this plant in the management of liver disorders.
