Pari Mala Manonmani, Palanichamy Mehalingam

The present investigation was aimed to evaluate the phytochemical screening and antimicrobial activity of rhizome extract of Zingiber is which belongs to the family Zingiberaceae. The rhizome is mainly used to cure digestive problems. The plant samples were shade- dried and were subjected to different solvent extracts such as ethanol, ethyl acetate and acetone. The preliminary phytochemical screening revealed the presence of alkaloids, anthraquinones, glycosides, flavonoids, phenols, tannins, saponins, quionones, coumarins and triterpenoids. Subsequently, these solvent extracts were tested against gram positive bacteria such as Bacillus subtilis, Streptococcus faecalis, Staphyllococcus aureus and gram negative bacteria such as Escherichia coli, Pseudomonas aeruginosa, Klebsiella pneumoniae and a fungal strain Candida albicans. It is evident from the results that maximum zone of inhibition was noticed with ethanol extract of Z. zerumbet against Staphylococcus aureus. These results confirmed that the tested plants may be effective and potential sources of natural antimicrobials.
