Antimicrobial activity of Crude Extract from Stemona tuberosa Lour

Abstract

In this research work, antifungal activity of the extracts from Stemona sp. were studied. The roots of this plant were macerated with hexane, acetone and ethanol sequentially. Antifungal activity of plant extracts were measured by paper disc diffusion method. Determination antifungal activity against Colletotrichum gloeosporioides of the extracts were measured at concentration of 62.5, 125, 250 and 500 mg/ml., respectively. The ethanol exteact and acetone extract of this plant gave the highest antifungal activity against Colletotrichum gloeosporioides at the concentration of 500 mg/ml, for 10 days. The percentage inhibition of the ethanol extract and acetone extract of this plant were 45.79 % and 39.90 % , respectively.
