Two new compounds from Cleidion brevipetiolatum

摘要

Two new compounds, 4-ethoxycarbonyloxy-3,3',4'-trimethoxy-ellagic acid (1) and 4-E-propenyl-phenol-1-O-beta-d-rutinoside (2), together with four known compounds, 3,3',4'-trimethoxy-ellagic acid (3), 3,3'-dimethoxy-ellagic acid (4), 3,3',4'-trimethoxy-ellagic acid-4-O-beta-d-glucopyranoside (5) and 3'-methoxy-ellagic acid-4-O-alpha-l-rhamnopyranoside (6), were isolated from the whole plant of Cleidion brevipetiolatum. Their structures were elucidated from spectral evidences.
