Phenolic constituents from fruit of Gardenia jasminosides var. radicans / 中草药

ABSTRACT

Objective To investigate the phenolic constituents in the fruit of Gardenia jasminosides var. radicans. Methods The phenolic constituents were isolated and identified by chromatography on silica gel, Toyopearl HW-40, Sephadex LH-20, MCI gel CHP-20, ODS, and RP-HPLC. Their structures were elucidated on the basis of physicochemical properties and spectral analyses. Results Seventeen compounds were isolated from 50% aqueous acetone extract from the fruit of Gardenia jasminosides var. radicans and identified as 3,3',5-trimethoxy-9,9'-epoxylignane-4,4'-diol (1), 3,4-divanillyltetrahydrofuran (2), marphenol C (3), sinapaldehyde (4), hydroxycinnamic acid (5), isoferulic acid (6), caffeic acid (7), isofraxidin (8), isoscopoletin (9), 6-methoxy-7-hydroxycoumarin (10), 6,7-dihydroxycoumarin (11), syringic acid (12), 3-hydroxy-4-methoxybenzoic acid (13), 3,4-dihydroxybenzoic acid (14), p-hydroxybenzoate (15), 4,5-dihydroxy-3-methoxy-benzoic acid (16), and gallic acid (17). Conclusion All 17 compounds are isolated from this plant for the first time.
