中华猕猴桃根化学成分的研究

Study on Chemical Constituents from the Root of Actinidiac chinensis Planch.

目的研究中华猕猴桃根的化学成分。方法采用硅胶柱色谱分离纯化,通过理化常数测定结合谱学分析鉴定化合物的结构。结果从中华猕猴桃根中分离并鉴定了7个化合物,分别为:β-谷甾醇(Ⅰ),硬脂酸葡萄糖苷(Ⅱ),胡萝卜苷(Ⅲ),表-儿茶素(Ⅳ),2α,3α,24-三羟基-12-烯-28-乌苏酸(Ⅴ),正丁基果糖苷(Ⅵ),蔗糖(Ⅶ)。结论化合物Ⅱ和Ⅵ为首次从该植物中分离得到。

Objective To study the chemical constituents of the root of Actinidia chinensis Planch.Methods The chemical constituents were isolated and purified by silica gel column chromatography and their structures were identified by physicochemical methods and spectroscopic analysis.Results Six compounds were isolated and identified as β-steriol(Ⅰ),stearyl-β-D-glucopyranoside(Ⅱ),daucosterol(Ⅲ),(-)-epi-catechin(Ⅳ),2α,3α,24-trihydr-oxyurs-12-en-28-oic acid(Ⅴ),n-butyl-β-D-fructopyranoside(Ⅵ) and sucrose(Ⅶ).Conclusion Compounds Ⅱ and Ⅵ were isolated from the root of Actinidia chinensis Planch.for the first time.
