ABSTRACT
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 tyramine (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)-6α-hydroxy-5α-spirostan-3-one-6-O- [α-Z,-rhamnopyranosyl-(1→3)- β-D-quinovopyraposide] (9), torvosides M (10), and 6α-O-[β-D-xylopyranosyl-(1→3)-beta;-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.
