Evaluation of In vitro Antifungal Activity of Some Plant Extractives

Abstract

Eugene Sebastian J Nidiry*

Thirty-two extractives of seven plants obtained using hexane, ethyl acetate and methanol were tested for their in vitro antifungal activity against the mycelial growth of Colletotrichum gloeosporioides. Among these extractives, ethyl acetate extractives of onion seeds, chilli seeds and chilli pericarps and methanol extractives of chilli seeds and chilli pericarps exhibited more than 20% mycelial growth inhibition at a concentration of 0.5% level. Methanol extractives of Solanum viarum berries and ethyl acetate extractive of soybean leaves exhibited more than 20% mycelial growth inhibition at a concentration of 1.0% level. Thin layer chromatographic bioautography showed that hexane and ethyl acetate extractives of onion seeds, chilli seeds and chilli pericarps exhibited spore germination inhibition of Cladosporium cucumerinum at a dose of 1.0 mg.
