Abstract

In the course of isolating bioactive constituents from the seeds of the locally grown Ipomoea muricata (Jacq.) Convolvulaceae, phenylpropanoids, phenylpropanoid glucosides and a phenylethanol diglucoside were isolated. A combination of (1)H and (13)C (1D and 2D) n.m.r. spectroscopy identified the compounds. The phenyl propanoids isolated were ethyl caffeate, caffeic acid and methyl p-coumarate. The phenylpropanoid glucosides identified were 6-0 (p-coumaroyl)-B-D-methylglucopyranoside and 6-0 (p-caoumaroyl)-alpha-D-methylglucopyranoside and the phenyletahanol diglucoside was identified as 2-{4-[0-B-D-glucopyranosyl(1-6)-B-D-glucopyranosyloxyl] phenyl}ethanol.
