  • Viqar Uddin Ahmad , Fehmida T. Baqai and Roshan Ahmad

A new monodesmosidic spirostanol glycoside extracted from the fresh leaves of Cestrum nocturnum was identified as spirost-5-ene-3-ol, [3β,25R]-3-O-[{α-L-rhamnopyranosyl-(1→4)- α-L-rhamnopyranosyl-(1→2)}-α-L-rhamnopyranosyl-(1→4)-β-D-glucopyranoside. The name proposed for this saponin is nocturnoside B. The structure elucidation was done on the basis of 1 D and 2 D spectroscopic studies [DEPT. HeteroCOSY, HMBC, COSY-45°, HOHAHA ] and chemical analysis.
