ABSTRACT

Aim of the research work is to study the antimicrobial activity of immature fruits of Syzygium cumini, and to identify the phytochemical group of the compounds showing antimicrobial activity. Syzygium cumini crude methanol fruit extract was screened for its antimicrobial activity against Gram negative and Gram positive bacterial cultures agar well diffusion method. Phytochemical group of the compounds showing antimicrobial activity was identified by TLC bioautography method. Crude methanol fruit extract showed significant antimicrobial activity only against Gram positive organisms but not against Gram negative organisms. TLC bioautography method identifies the antimicrobial compounds as phenolic compounds. The results revealed that the phenolic compounds present in immature fruits of Syzygium cumini, possess significant antimicrobial activity against Gram positive organisms and can be used as a source of herbal antimicrobial agent.
