Chemical Constituents from Solanum torvum

To investigate the chemical constituents of Solanum torvum Swartz. The compounds were isolated by silica gel, Sephadex LH-20, and Rp-C18 column chromatography. Their structures were elucidated on the basis of spectral analysis of ESI-MS and NMR. Nine known compounds including neochlorogenin 6-O-β-D-quinovopyranoside (1), neochlorogenin 6-O-β-D-xylopyranosyl-(1→3)β-D-quinovopyranoside (2), neochlorogenin 6-O-α-L-rhamnopyranosyl-(1→3)-β-D-quinovopyranoside (3), solagenin 6-O-β-D-quinovopyranoside (4), solagenin 6-O-α-L-rhamnopyranosyl-(1→3)-β-D-quinovopyranoside (5), isoquercetin (6), rutin (7), kaempferol (8) and quercetin (9) were isolated from S. torvum. All compounds were isolated from S. torvum for the first time.
