???displayArticle.abstract???
OBJECTIVE: To study the chemical constituents from the seeds of Euryale ferox. METHODS: The chemical constituents were isolated by silica gel column, Sephadex LH-20 and their structures were identified by physico-chemical and spectral analysis. RESULTS: Seven compounds were purified from the 95% ethanol extract. These constituents were elucidated as protocatechuic acid (1), gallic acid (2), gallic acid ethyl ester(3),5 ,7-dihydroxychromone(4), β-sitosterol(5), daucosterol(6), and 5,7-dihydroxy-6,4''-dimethoxyflavone(7), respectively. CONCLUSION: All compounds are isolated from this plant for the first time.
