Objective To study the chemical constituents from the fruits of Tribulus terrester. Methods The constituents were isolated and purified by silica gel column chromatography, Sephadex LH-20 column chromatography, preparative HPLC and TLC methods. The structures were identified by HR-ESI-MS and spectral analysis methods. Results Fourteen compounds were isolated from the fruits of Tribulus terrester and the structures were identified as N-p-feruloyltyramine (1), N-trans-p-coumaroyl-3-O-methyldopamine (2), methyl ferulic acid (3), caffeic acid methyl ester (4), protocatechuic acid methyl ester (5), trifilines A (6), 5β-spirost-25(27)-en-3β-ol-12-one 3-O-{β-D-glucopyranosyl-(1→2)-O-[β-D-glucopyranosyl-(1→3)]-β-D-glucopyranoside} (7), tribulosaponin B (8), isoterrestrosin B (9), 25(R)-spirostane-3,5-diene-12-one (10), 25 (R)-spirostane-24β-ol-4-ene-3,12-dione (11), 26-O-β-D-glucopyranosyl-(25S)-5α-furostane-20 (22)-en-12-one-3β,26-diol-3-O-α-L-rhamnopyranosyl-(1→2)-[β-D-glucopyranosyl-(1→4)]-β-D-galactopyranoside (12), terrestrinone A1 (13), and terrestrinone A2 (14). Conclusion Compounds 1-7 are obtained from the Zygophllyaceae for the first time.
