ANTIOXIDANT AND ANTIMICROBIAL ACTIVITIES OF RHIZOME EXTRACTS OF Kaempferia galanga
Narasinga Rao V, DSVGK Kaladhar*
ABSTRACT Several Zingiberaceae family members show active principles in treatment of various human ailments. An experiment on antioxidant and antimicrobial activity in rhizome extracts of Kaempferia galanga has been conducted. The Kaempferia galanga rhizome extracts shown antioxidant activity of the tested plant extracts (IC50: 490μg/ml to 720μg/ml) is less compared to the ascorbic acid (IC50: 230μg/ml). Methanol, ethylacetate, ethanol and aqueous rhizome extracts has shown good antimicrobial activity against tested microbes (9.5 to 22mm zone diameter). The extracts was shown good antimicrobial activity against fungi (11 to 22mm) when compared with the gram negative bacteria (9.5 to 15mm) and gram positive bacteria (9.5 to 13). Hence Kaempferia galanga rhizome extracts was shown good antioxidant and antimicrobial activities.
