ISOLATION OF NEW AROMATIC ESTER FROM PLUMERIA ACUTIFOLIA BARK

It is a small deciduous tree, contains copious milky juice. It is native of Mexico and cultivated in Indian gardens. The root bark is bitter and useful in leprosy, pains, fever. The infrequent fatty acids, glycosides sugar derivatives and new aromatic ester were isolated form methanol extract of stem bark of plant Plumeria acutifolia . The structures of these three compounds were recognized on the basis of chemical reactions and spectral analysis as n-octyl stearate, heptoglucosyl rhamoside and a new aromatic ester a vanillic acid-O-tetraarabinosyl stearate. This study advocates that plant contain a large number of bioactive compounds.
