| Popis: | A new acylated kaurene diterpene, characterized as 15alpha-decanoyloxy-kaur-16-en-19-oic acid, along with nine known compounds: pentacosanoic acid, 24alpha-ethyl-5alpha-cholesta-7,22E-dien-3beta-ol, 15alpha-hydroxy-kaur-16-en-19-oic acid, 8beta-angeloyloxy-9beta,10beta-dihydroxy-1-oxo-germacra-4E,11(13)dien-12,6alpha-olide, 3beta-hydroxyeicosan-1,5beta-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 alpha- and beta-amyrin, while the mixture of beta-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. |
