A New Taraxastane-Type Triterpene from the Flowers of Inula cappa

摘要

A new taraxastane-type triterpene, named 3 beta-hydroxy-20-taraxasten-22-one palmitate (1), along with a known compound, taraxasterol palmitate (2), was isolated from the flowers of Inula cappa, and the structure was elucidated on the basis of one- and two-dimensional NMR (including H-1, C-13 NMR, DEPT, H-1-H-1 COSY, HSQC, HMBC, and NOESY).
