米碎花茎枝的化学成分研究

Chemical Constituents from the Stems of Eurya chinensis

摘要:

为探讨山茶科(Theaceae)柃木属植物米碎花(Eurya chinensis R. Brown)茎枝的化学成分,从米碎花茎枝95% 乙醇提取物中分离得到8 个化合物。根据现代波谱技术和文献对照,鉴定其结构分别为:高根二醇(1)、白桦酸(2)、木栓酮(3)、羽扇豆醇(4)、β-谷甾醇(5)、豆甾醇(6)、邻羟基苯甲醛(7)、正二十九烷醇(8)。所有化合物均为首次从该植物中分离得到。

Abstract:

To study the chemical constituents of Eurya chinensis R. Brown, eight compounds were isolated from the 95% ethanol extract of its stems. They were identified by comparison of their spectroscopic data with those reported in the literature and elucidated as: erythrodiol (1), betulinic acid (2), friedelin (3), lupeol (4), β-sitosterol (5), stigmasterol (6), salicylic aldehyde (7), nonacosanol (8). All the compounds were obtained from Eurya chinensis for the first time.
