Abstract
Vicolide A to D, sesquiterpenoid lactones, were isolated from “Vicoa indica” and crystal structure of A and D were established by X-ray analysis. The structures were solved by direct methods and refined to an R index of 0.09. Vicolide B and D are reported to have anti-fertility activity while A and C are devoid of this activity. Conformational features of B and C are similar but differ from those of A and C.
