[Studies on non-alkaloid constituents from Ochrosia elliptica].
The chemical consituents from Ochrosia elliptica were separated and purified by column chromatographies on silica gel, Sephadex LH-20, ODS and RP-HPLC. The structures of the isolated compounds were identified on the basis of physicochemical properties and spectroscopic analysis, as well as comparisons with the data in the literature. 18 compounds were isolated and elucidated as (+) -pinoresinol(1), (+) -medioresinol (2), (+) -lariciresinol (3), (+) -5'-methoxy lariciresinol(4), (+) -isolariciresinol (5), syringaresinol(6), episyringaresinol (7), ciwujiatone (8), zhebeiresinol (9), 7-hydroxycoumarin (10), 7-methoxycoumarin (11), scopoletin(12), isofraxidin(13), caffeic acid ethyl ester (14), ferulic acid (15), p-hydroxybenzaldehyde (16), vanillin (17), and vanillic acid(18). All compounds were isolated from the genus Ochrosia for the first time.
