Objective: To study the chemical constituents from the aerial parts 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 in the methanol extract from the aerial parts of F. dibotrys and their structures were identified as benzoic acid (1), p-hydroxybenzoic acid (2), p-hydroxy benzaldehyde (3), 3,4-dihydroxy benzoic acid (4), succinic acid (5), caffeic acid (6), methyl caffeate acid (7), luteolin (8), tricin (9), quercetin (10), afzelin A (11), 2α,3β,29-trihydroxyolean-12-en-28-oic acid (12), yarumic acid (13), and 3α-hydroxy-urs-12,15-dien (14). Conclusion: Compounds 2-3 and 6-9 are firstly obtained from the aerial parts of F. dibotrys. Compounds 11-14 are isolated from the genus of Fagopyrum Mill. for the first time. © 2016, Editorial Office of Chinese Traditional and Herbal Drugs. All right reserved.

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. © 2016, Editorial Office of Chinese Traditional and Herbal Drugs. All right reserved.
