Two triterpenoids, taraxerone and tricadenic acid A were isolated from the methanol extract of the outer bark of Schleichera oleosa available in Darjeeling foothills. A preliminary study on their antimicrobial activities was also performed against some fungal and bacterial species. The structure of these compounds was determined by means of chemical characterisation and IR, NMR spectral data.
