Abstract

The anti-fungal compound isolated from the petroleum and ethyl acetate extracts of the stem bark from Butea from Butea monosperma identified as (-)-3 hydroxy-9-methoxypterocarpan    [(-)-medicarpin]. Both (-)-medicarpin and its acetate were active against Cladosporium cladosporioides. The petroleum extract also yielded lupenone, lupeol and sitosterol. Two isoflavones isolated from the ethyl acetate ext  ract were found to be 5-methoxygenistein and prunetin.
