Phytochemistry and Biological Activities

A new type of sesquiterpenes, illicinolides A (1) and B (2) has been isolated from Illicium tashiroi. The structure of illicinolide A was established by X-ray analysis of the p-bromobenzoyl derivative. Illicinolide B was assigned the structure as 9α-hydroxyillicinolide A by spectral data compared with those of illicinolide A. They are biogenetically closely related to anisatin (3) and its derivative.
