Objective To investigate the chemical constituents of the whole plants of Viola yedoensis.Methods The chemical constituents were isolated and purified by column chromatography over silica gel and Sephadex LH-20, as well as on the semi-preparative HPLC.The structures of the isolates were identified by the NMR spectroscopic method.Results Twenty-three compounds were isolated and their structures were identified as pubinernoid A (1), (2R, 6R, 9R)-2, 9-dihydroxy-4-megastigmen-3-one (2), 3S, 5R-dihydroxy-6R, 7-megastigmadien-9-one (3), dehydrovomifoliol (4), blumenol A (5), blumenol B (6), oleanolic acid (7), 2α, 3α-dihydroxyurs-12-ene-28-oic acid (8), 1α, 2α, 3β-trihydroxyolean-12-ene-28-oic acid (9), 2α, 19α-dihydroxyursolic acid (10), 3α-hydroxyfriedel-2-one (11), 7-oxopetrosterol (12), 7-oxositosterol (13), syringaresinol (14), lariciresinol (15), daphneticin (16), umbelliferone (17), trans-p-hydroxycinnamic acid methyl ester (18), p-hydroxyphenylpropionic acid (19), p-hydrobenzaldehyde (20), p-methoxybenzaldehyde (21), p-methoxybenzoic acid (22), and 5-hydroxymethyl-2-furfural (23).Conclusion Compounds 1-16 and 18-23 are isolated from the genus Viol for the first time, and compound 17 is isolated from the plant for the first time.
