Abstract:
Objective: To study the chemical constituents of the stems and leaves of semi-mangrove plant, Barringtonia racemosa. Methods: The chemical constituents of B. racemosa were separated and purified by silica gel, ODS, Sephadex LH-20 gel column chromatographies and preparative HPLC. Their structures were identified by physicochemical properties, spectroscopic analysis, as well as comparisons with the data reported in literature. Results: A total of 17 compounds were isolated from the 90% ethanol extract of the stems and leaves of B. racemosa, which were identified as chrysin (1), ayanin (2), genkwanin (3), rhamnocitrin (4), tricin (5), dillenetin (6), 5,3'-dihydroxy-7,4'-dimethoxyflavone (7), 5,7,3',4'-tetramethoxyflavone (8), 5-hydroxy-6,7,8,3',4'- pentamethoxy flavone (9), petasitolone (10), sarmentol F (11), dehydrovomifoliol (12), blumenol A (13), 10-hydroxyaristolan-9-one (14), alphitolic acid (15), oleanolic lactone (16), and 11,12-dehydroursolic acid lactone (17). Conclusion: All compounds are isolated from the genus Barringtonia for the first time.
