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.
