New sesquiterpene lactones from Liriodendron tulipifera
TL;DR: In this article, four sesquiterpene lactones were obtained from L. tulipifera; two germacranolides, lipiferolide (4 ) and epitulipinolide diepoxide (5 ) from the leaves, an elemanolide, epitulo-denoide (7 ), and an eudesmanolate, γ-liriodenolide from the root bark.
