Salacca wallichiana Mart or paratungon in Filipino, belong to the family of Arecaceae. The fleshes, seeds, female flowers and roots of paratungon were extracted by dichloromethane (DCM) and chromatographic separation yielded (1) triacylglycerol, (2) B-sitosterol with stigmasterol, (3) B-sitostery1-3B-glucopyranoside-6 -O-fatty acid ester, (4)Monogalactosyl diacylglycerol were isolated from the fleshes of paratungon. Compound (3) and linoleic acid (5) were isolated from the seeds while mixture (2) was also isolated from the roots. B-sitosterone (6) was isolated from the crude extract of female flowers. The structures were identified by I-D NMR spectroscopy with comparison to published literatures while monogalactosyl diacylglycerol (4) was elucidated by 2-D NMR data. To determine the chain length of fatty acids attached in compounds (1), (3) and (4). The biological activities of the isolates may be identified by subjecting the compounds into bioassay.
