    Abstract

    Kaempferol 3-0-(2",6" -di-O-E-p-coumaroyl)-βD-galactopyranoside (1), kaempferol3-0-β-D-galactopyranoside (2), kaemptero13-0-α-L-rhamnopyranoside (3), kaempfero13-O-β-D-g1ucopyranoside (4), kaempferol (5), and quercetin (6) were isolated along with ellagic acid (7) from the ethyl acetate soluble part of an aqueous methanoIic (90%) extract of the flowers of Melastoma malabathricum L., and their identities established by spectroscopic methods. All these compounds except (5) are being isolated for the first time from the flowers of this plant, and the identification of (1) in a plant has only been reported once before.
