| Abstract: | From the aerial parts of Solenostemma argel, four new acylated phenolic glycosides sinapyl alcohol 9-O-feruloyl-4-O-alpha-rhamnopyranosyl-(1-->2)-beta-glucopyranoside, solargin I (1), sinapyl alcohol 9-O-caffeoyl-4-O-alpha-rhamnopyranosyl-(1-->2)-beta-glucopyranoside, solargin II (2), sinapyl alcohol 9-O-feruloyl-4-O-alpha-rhamnopyranosyl-(1-->2)-alpha-rhamnopyranosyl-(1-->2)-beta-glucopyranoside, solargin III (3) and sinapyl alcohol 9-O-caffeoyl-4-O-alpha-rhamnopyranosyl-(1-->2)-alpha-rhamnopyranosyl-(1-->2)-beta-glucopyranoside, solargin IV (4) have been isolated. The structures of the isolated compounds were verified by means of MS and NMR spectral analyses. |
