Abstract:
Two new picrotoxane-type sesquiterpenoid lactones, dendrowillins A (1) and B (2), together with five known sesquiterpenoids, (−)-picrotin (3), α-dihydropicrotoxinin (4), dendronobilin B (5), amoenin (6), and (−)-10β,13,14-trihydroxyalloaromadendrane (7), were isolated from the whole plants of Dendrobium williamsonii. Their structures were elucidated by means of extensive spectroscopic analysis.
