Total phenolic contents, antioxidant and antimicrobial activities of Bruguiera gymnorrhiza

In the present work, the antioxidant and antibacterial activities of methanolic, ethanolic and chloroform crude extract of leaves and barks of Bruguiera gymnorrhiza were investigated. The antioxidant activity of the crude extracts were evaluated using the enzymatic and non enzymatic methods namely s...
