Amides and lignans from Solanum lyratum

Sixteen non-steroidal compounds including four amides, six lignans, two sesquiterpenoids and three flavonoids, were isolated from the 80 % ethanol extract of whole plants of Solanum lyratum Thunb. Their structures were assigned based on analyses of extensive spectroscopic data (including MS, 1D/2D NMR and ORD) or comparisons of the NMR data with those reported. Among them, there were a new lignan namely isolariciresinol-9-acetate (5), a new...
