Phytochemical Screening and Evaluation of Syzygium jambolanum seeds for In- vitro Antimicrobial Potential against Herbal Drugs Contaminants

Abstract

The disc diffusion method, MIC and MBC were used to test the antibacterial activity of methanol, aqueous, ethyl acetate extract and essential oils of Cymbopogon citratus leaves, and Syzygium jambolanum seeds against Escherichia coli and Bacillus cereus, which were isolated from herbal medicines. Methanolic extract of Syzygium jambolanum was highly active against Bacillus cereus and E. coli. Chemical analysis was done by GC- MS. All the plant extracts showed different kinds of phytochemicals like terpenoids, flavonoids and steroids etc.
