摘要：

In a previous paper,1 we reported the structure elucidation of O-p-coumaryl dryocrassol, a new compound isolated along with the known compounds tectoquinone, kaempferol, kaempferol-3-β-D-glucoside, β-sitosterol, stigmasterol, and dryocrassol itself from Lygodium flex-uosurn (Polypodiaceae), a fern widely distributed in India and known to possess potent antifertility activity.2 Further investigation on the methanolic extract of this plant afforded, in 0.002% yield, yet another new compound, lygodinolide (1), the characterization of which is described herein. © 1990, American Chemical Society.
