小花异裂菊中的微量新成分

Minor new constituents from Heteroplexis micocephala

  • 摘要:

    通过硅胶和Pharmadex LH-20凝胶柱色谱以及反相HPLC等多种分离技术的组合应用, 从小花异裂菊全草乙醇提取物中分离得到了2个微量新化合物: 半日花烷-12, 14-二烯-6β, 7α, 8β, 17-四醇 (1) 2, 3-顺式-6-乙酰基-5-羟基-2-(羟甲基乙烯基)-2, 3-二氢苯并呋喃-3-醇当归酸酯 (2), 以及1个微量新天然产物: 6-甲氧基-4-甲基-3, 4-二氢-2H-1-萘酮 (3)。运用包括二维核磁共振实验的波谱学数据解析确定了它们的结构。

     

    Abstract:

    By using a combination of various chromatographic techniques including column chromatography over silica gel and Pharmadex LH-20 and reversed-phase HPLC, two minor new compounds, labda-12, 14-dien- 6β, 7α, 8β, 17-tetraol (1), 2, 3-cis-6-acetyl-5-hydroxy-2-(hydroxymethylvinyl)-2, 3-dihydrobenzofuran-3-ol angelate (2), and a minor new natural product 6-methoxy-4-methyl-3, 4-dihydro-2H-naphthalen-1-one (3) have been isolated from an ethanolic extract of Heteroplexis micocephala.  Their structures were elucidated with spectroscopic data analysis including 2D NMR experiments.
