Four undescribed steroidal compounds along with twenty known compounds were isolated from n‐butanol extracted fraction of the whole plants of Solanum lyratum Thunb (SLNF). Their structures were assigned based on analyses of the extensive spectroscopic data (including MS, 1D/2D NMR, and ECD) or comparisons of the NMR data with those reported. Among the knowns, three compounds were isolated from Solanum...
Chemical investigation on the water‐soluble constituents of Stemona tuberosa Lour. resulted in the isolation of a previously undescribed furfural derivative namely (S)‐5‐((R)‐hydroxy(5‐(hydroxymethyl)furan‐2‐yl)methyl)‐5‐methylfuran‐2(5H)‐one and twenty‐five known compounds from the water decoction of the dried root tubers. Their structures were determined by analysis of the extensive spectroscopic...
