Abstract:
The chemical investigation of Cucubalus baccifer L. afforded three new norsesquiterpenoids, cucubalol, cucubalactone and drummondol-11-O-beta-D-glucopyranoside together with two known related compounds, drummondol and 5,7[E]-megastigmadiene-3 beta,4 alpha,9 xi-triol. Their structures were established based on spectral and chemical evidence. No activity was observed in anti-cancer (CDC25), antibacterial (PEPT) and antifungal (YNG) assays.
