Abstract:
One new neolignan identified as 2, 3-( trans) -dihydro-2-(4-hydroxy-3-methoxyphenyl) -3-[(beta-D-glucopyranosyloxy) methyl]-7-methoxybenzofuran-5-propenoic acid (1) and five known steroidal glycosides namely torvoside A(2), torvoside C(3), torvoside H(4), solanolactoside A (5), (25S)-6alpha-hydroxy-5alpha-spirostan-3-one-6-0-[alpha-L-rhamnopyranosyl-(1-->3-beta3)-beta-D-D-quinovopyr-anoside] (6) were isolated from the fruits of Solanum torvum. Their structures were elucidated on the basis of 1D, 2D NMR and MS spectroscopic analysis.
