The chemical constituents were separated and purified from the roots and rhizomes of Smilax scobinicaulis by various chromatographic methods including silica gel, Sephadex LH-20. Their structures were obtained and identified as resveratrol-3-O-beta-D-glucopyranosyl-(1-->3)-beta-D-glucopyranoside (1), resveratrol (2), 8-viniferin (3), ethyl caffeate (4), 1-0-caffeoylglycerol (5), 1-O-p-coumaroylglycerol (6), 1-0-feruloylglycerol (7), grossamide (8), moracin M (9) on the analysis of spectroscopic data. Compound 1 was a new compound and compounds 3-5, 8,9 were separated from this plant for the first time.
