Total Polyphenol content and antioxidant activities of Zizyphus Mauritiana Lam

Evaluate total Polyphenol content and antioxidant activities of the methanol extract Zizyphus Mauritiana Lam. The total Polyphenol content in Z. Mauritiana leaves and twigs are 97.75 mg/g and 26.92 mg/g catechin respectively. The antioxidant activities were measured by 2,2-diphenyl-1-picrylhydrazyl...
