Phenolic acids from fruits of Euscaphis fukienensis

Objective To investigate the compouds from methylene dichloride and n-butyl alcohol parts of 70% ethanol extract of the fruits of Euscaphis fukienensis. Methods The compounds were isolated and purified by Sephadex LH-20, silica gel column chromatographies, and recrystallization. Their structures were identified by physicochemical properties and spectroscopic methods. Results Ten compounds were isolated and identified as 1, 2-benzenedicarboxylic acid(1), butanedioic acid(2), gallic acid(3), isorhamnetin-3-O-glucoside(4), 4-hydroxy-benzoic acid(5), 2-methyl-5, 7-dihydroxychrom one(6), muconic acid(7), quercetin-3-Oglycosidase(8), β-sitosterol(9), and daucostrol(10). Conclusion Compounds 1—7 are isolated from the fruits of E. fukienensis for the first time.
