Chemical constituents from Euscaphis fukienensis / 中草药

ABSTRACT

Objective: To investigate the chemical constituents from the fruit of Euscaphis fukienensis. Methods: The chemical constituents were isolated and purified by silica gel, Sephadex LH-20 column chromatography and liquid phase preparation, and the structure were elucidated on the basis of nuclear magnetic technique. Results: Eighteen compounds were obtained from the fruit of E. fukienensis, which were named as betulinic acid (1), tetraketide (2), β-sitosterol (3), oleanolic acid (4), pomolic acid (5). β-amyrin (6), gallic acid (7), 3,3’-dimethoxy ellagic acid (8), quercetin (9), kaempferol (10), isorhamnetin (11), 2-epitormentic acid (12), 3,3’,4’-trimethoxy ellagic acid (13), 1-oxosiaresinolic acid (14), 2-oxopomolic acid (15), momordic acid (16), ursolic acid (17), isorhamnetin-3-O-rutinoside (18). Conclusion: Compounds 6, 11-15 and 18 are isolated from E. fukienensis for the first time, and compounds 13-15 are isolated from the genus Euscaphis for the first time.
