Abstract:
Objective: To study the chemical constituents from the root tubers of Fagopyrum dibotrys. Methods: The compounds were isolated and purified by means of chromatographic techniques and their structures were identified on the basis of spectral features. Results: Fourteen known compounds were isolated from methanol extract in the dry roots of F. dibotrys and thier structures were identified as luteolin (1), tricin (2), luteolin-7,4'-dimethyl ether (3), quercetin (4), genkwanin (5), chrysoeriol (6), protocatechuic acid (7), protocatechuic acid methyl ester (8), p-hydroxybenzaldehyde (9), glutinone (10), glutinol (11), olean-12-ene-3β, 7β, 15α, 28-tetraol (12), juglangenin A (13), and 21β-dihydroxy-olean-12-ene (14). Conclusion: Compounds 5 and 6 are firstly obtained from F. dibotrys. Compounds 12-14 are isolated from the plants of Fagopyrum Mill. for the first time.
