Objective To study the chemical constituents of Solanum torvum.Methods Column chromatography was used to isolate and purify the constituents, whose structures were identified on the basis of spectral data analyses.Results Eleven compounds were isolated and identified as N-trans-feruloyl tyrsmine (1), N-trans-P-coumaroyl tyramine (2), 3-(4-hydroxyphenyl)-N-[2-(4-hydroxyphenyl)-2-methoxyethyl]-acrylamide (3), N-trans-P-coumaroyl octopamine (4), kaempferol (5), quercetin (6), trans-caffeic acid (7), solagenin 6-O-(β-D-quinovopyranoside) (8), (25S)-6a-hydroxy-5α-spirostan-3-one-6-O-[α-L-rhamnopyranosyl-(1→3)-β- D-quinovopyranoside](9), torvosides M (10), and 6α-O-[β-D-xylopyranosyl-(l→3)-β-D-quinovopyranosyl]-(25S)-5α-spirostan- 3β-ol(11).Conclusion Compound 3 is firstly reported as a new natural product Compounds 1-7 are isolated from S.torvum for the first time.
