ABSTRACT

Various Zingiberaceous plants show good phytocompounds in treatment of various human ailments. An experimentation on antioxidant and antimicrobial activity in tuber extracts of Globba bulbifera has been conducted. The Globba bulbifera tuber extracts shown antioxidant activity of the tested plant extracts (490 μg/ml to 680 μg/ml) is less compared to the standard (40 μg/ml). Methanol, ethanol, ethyl acetate and aqueous tuber extracts has shown good antimicrobial activity against tested microbes (9 to 32mm zone diameter). The extracts have shown good activity against fungi (10 to 23 mm) when compared with gram negative bacteria (10 to 21 mm) and gram positive bacteria (9 to 21mm). Hence Globba bulbifera tuber extracts has shown good antioxidant and antimicrobial activities.

Keywords: Globba bulbifera, solvent extraction, antimicrobial activity, antioxidant studies.
