人工栽培的南方红豆杉化学成分研究(III)

Studies on chemical constituents of planted Taxus mairei (III)

    摘要
  • 摘要: 从人工栽培的南方红豆杉全株乙醇提取物的氯仿萃取部位通过反复硅胶和凝胶柱层析分离得到4个化合物，采用波谱解析(IR，ESI-MS，1H NMR和13C NMR)等方法确定了其结构，4个化合物分别鉴定为taxamairin K (1), 2α,4α-dideacetoxy-7β-benzoyloxy-5β,20-epoxy-9α,10β,13α,15-tetrahydroxy-11(15→1)abeotaxa-11-ene (2), 7β-xylosyl-taxol (3), 10-deacetoxy-7-xylosyl-taxol (4)，其中化合物1为新化合物。

     

    Abstract: From the chloroform-soluble fraction of the ethanol extracts of the whole plant of Taxus chinensis<.i> var. mairei (Lemee et Levl), four compounds were isolated by using repeated column chromatography on silica gel and Sephadex LH-20. Based on spectroscopic data (UV, IR, ESI-MS, 1H NMR and 13C NMR), the compounds were identified as taxamairin K (1), 2α, 4α-dideacetoxy-7β-benzoyloxy-5β,20-epoxy-9α,10β,13α,15-tetrahydroxy-11(15→1)abeotaxa-11-ene (2), 7β-xylosyl-taxol (3), 10-deacetoxy-7-xylosyl-taxol (4). Among them, taxamairin K is a new compound.
