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.
