瓜蒌化学成分的分离与鉴定

目的研究葫芦科栝楼属植物栝楼果实体积分数为90%乙醇提取物的正丁醇部分,对其中的化学成分进行分离鉴定。方法利用硅胶柱色谱,凝胶柱色谱(Sephadex LH-20),反相中低压柱色谱,制备高效液相色谱(PRE-HPLC)等手段进行分离纯化,根据理化性质和光谱数据对化合物进行了结构鉴定。结果从瓜蒌的正丁醇萃取部分分离得到10个化合物,分别鉴定为:甲基-β-D-吡喃果糖苷(methyl-β-D-frucopyranoside,1)、乙基-β-D-吡喃果糖苷(ethyl-β-D-frucopyranoside,2)、正丁基-β-D-吡喃果糖苷(n-butyl-β-D-fructopyranoside,3)、乙基-β-D-呋喃葡萄糖苷(ethyl-β-D-glu-cofuranoside4,)、正丁基-α-D-呋喃果糖苷(n-butyl-α-D-fructofuranoside5,)、正丁基-β-D-呋喃果糖苷(n-butyl-β-D-fructofuranoside,6)、bluemenol A(7)、cucumegastigmanesⅠ(8)、5-羟甲基糠醛(5-hydroxymethylfurfural9,)5、5,'-双氧甲基呋喃醛(5,5'-oxybis(methylene)difurfural1,0)。结论化合物1-8均为首次从该植物中分离得到。

Isolation and identification of chemical constituents from Trichosanthes kirilowii Maxim.

Objective To isolate and identify the chemical constituents of the butanol extract part of the Trichosanthes kirilowii Maxim.ethanol extract. Methods The chemical constituents of T kirilowii Maxim.were studied by multiple chromatographic techniques(such as silica gel chromatography,Sephadex LH-20,and HPLC etc.).These compounds were identified by analysis of the spectral data and chemical properties. Results On the basis of physico-chemical evidence and spectral analysis,the structures of the 10 compounds we...
