ANTIFUNGAL POTENTIAL OF ARAUCARIA CUNNINGHAMII SWEET (ARAUCARIACEAE) PLANT EXTRACTS.

International Journal of Pharmacology & Toxicology Science 2013;3(1): 15-21.

Abstract

The antifungal activity of methanol, ethanol, chloroform, hexane and water extracts of Araucaria cunninghamii, a Kumaun Himalayan gymnosperm, were tested against seven fungal strains (Alternaria alternata, Colletotrichum falcatum, Fusarium oxysporum, Pyricularia oryzae, Sclerotinia rolfsii, Sclerotinia sclerotiorum and Tilletia indica) using agar-well diffusion method. The hexane extract was found very active towards all the pathogens tested (Percent inhibition, 47-57%) followed by ethanol extract (Percent inhibition, 37-52%), methanol extract (30-52%) and chloroform (32-51%). The inhibitory activity of these extracts was found very effective as compared to Clotrimazol, standard antifungal agent that was used as positive control against tested fungal strains.

Keywords: Antifungal activity, Araucaria cunninghamii, clotrimazol, Kumaun Himalaya, Plant extracts.
