Objective To investigate the chemical constituents of Campylotropis trigonoclada. Methods The chemical constituents were isolated by the combination of HPD-100, silica gel, RP-18, Sephadex LH-20 and high performance liquid chromatography. Their structures were elucidated on the basis of spectroscopic analysis (MS, NMR, etc.). Results Twenty-four compounds were isolated from the extract of C. trigonoclada and identified as (+)-catechin (1), rutin (2), quercetin-3-O- α-L-arabinopyranoside (3), avicularin (4), quercetin-3-O-glucoside (5), quercetin-3-O-β-D-xylpyranoside (6), luteolin-7-O- β-gentiobioside (7), orientin (8), isovitexin-2″-O-β-D-glucopyranoside (9), voilanthin (10), genistein (11), bolusanthin III (12), orobol-7-O-glucoside (13), piceatannol 4'-O-β-D-glucopyranoside (14), (Z)-polydatin (15), dihydrophaseic acid (16), millettiaspecoside B (17), esculetin (18), alternariol (19), dibutylphthalate (20), di(2-ethylhexyl)phthalate (21), methyl 2,4-dihydrox-3,6-dimethylbenzoate (22), 3,4-dihydroxybenzaldehyde (23) and ethyl gallate (24). There were 13 flavonoids, two stilbene glycosides, one sesquiterpenoid, one phenol glycoside, one coumarin and six other aromatic compounds. Conclusion Except for compound 11, the other 23 compounds were isolated from the genus Campylotropis for the first time.
