【 摘 要 】

A new acylated kaurene diterpene, characterized as 15a-decanoyloxy-kaur-16-en-19-oic acid, along with nine known compounds: pentacosanoic acid, 24a-ethyl-5a-cholesta-7,22E-dien-3b-ol, 15a-hydroxy-kaur-16-en-19-oic acid, 8b-angeloyloxy-9b,10b-dihydroxy-1-oxo-germacra-4E,11(13)dien-12,6a-olide, 3b-hydroxyeicosan-1,5b-olide, taraxasteryl acetate, 7-O-methylkaempferol, kaempferol, and nepetin were isolated from the flowers of Eupatorium betonicaeforme (Asteraceae). In addition, from the aerial parts were isolated taraxasteryl acetate and a- and b-amyrin, while the mixture of b-sitosterol and stigmasterol, and 6-acetyl-2,2-dimethylchroman-4-one were isolated from the roots. The structure elucidation of all compounds was performed by spectroscopic analysis and comparison with published data from literature.
