Antioxidant Activities and Functional Composition Content of Phyllanthus emblica L.Fruits

The contents of total polyphenol,flavonoids,and polysaccharide in the fruits of Phyllanthus emblica from three provinces,the scavenging activities of 1,1-diphenyl-2-picrylhydr -azyl radical,hydroxyl radical,superoxide anion radical and reducing power of the extracts from the fruits of P.emblica were evaluated.The results showed that the extracts from the Guangdong wild Emblica fruits had the highest contents of total polyphenol,flavonoids,and polysaccharide,reaching up to(204.15±6.85) mg of gallic acid equivalents,(81.11±8.67) mg of rutin equivalents,and (19.78±1.22) mg of glucose equivalents in 1 g of dry material,respectively.This extract possessed the highest antioxidative activity,and the values of scavenging activities of hydroxyl radical,superoxide anion radical and reducing power were 91.50%±3.53%,92.31%±1.30%,and 1.344±0.14,respectively.Guangdong cultivated fruit has the highest scavenging activities of DPPH radical with a value of 92.09%±1.52%.
