Evaluation of Anti-Bacterial Activity with Tannin Fraction fromPsidium guajava leaves and barks

Abstract

Objective: The Ethnobotanical studies and folklore claiming reviewed that the leaves and bark of the plant Psidium guajava Linn. are used for anti-bacterial activity. From the literatures we found that poly-phenolic compounds like tannin have significant free radical scavenging activity in bacterial associated diseases. Based on the above information of Psidium guajava is selected for this Research work. • To separate the tannin fraction from the Psidium guajava Linn., leaves and bark. • To study the anti-bacterial activity of tannin fraction of Psidium guajava separated from leaf and bark.
