摘要 从新山毛榉的茎中分离得到一种新的三萜醇,其结构为24-亚甲基-25-甲基环木霉醇。此外,除了常见的三萜醇和甾醇外,还从植物材料中分离并鉴定了以下不常见的化合物:(24 E )- 和 (24 Z )-24-亚乙基环木霉醇、(24 E )- 和 (24 Z )-24-亚乙基-5α-lanost-8-en-3β-ol, 24-methylene-24(25)-dihydroparkeol, 24-methylene-5α-lanosta-7,9(11)-dien-3β-ol, 24-亚甲基达马烯酚,14α,24-二甲基-5α-cholest-9(11)-en-3β-ol,14α-methyl-24α-ethyl-5α-cholest-9(11)-en-的C-24差向异构体3β-ol 和 24α-ethyl-5α-cholestan-3α-ol。
Abstract A new triterpene alcohol isolated from the stems of Neolitsea sericea was shown to have the structure 24-methylene-25-methylcycloartanol. Moreover, in addition to the common triterpene alcohols and sterols, the following uncommon compounds were isolated from the plant material and were identified: (24 E )- and (24 Z )-24-ethylidenecycloartanol, (24 E )- and (24 Z )-24-ethylidene-5α-lanost-8-en-3β-ol
