目的:
2
研究三叶木通藤茎正丁醇萃取物的化学成分。
方法:
2
取三叶木通的藤茎100 kg,采用75%乙醇加热回流提取3次,减压回收溶剂成浸膏。浸膏加适量的水混匀后,依次用二氯甲烷、乙酸乙酯、正丁醇进行萃取。正丁醇层萃取物经大孔树脂柱色谱,硅胶柱色谱,LH-20型羟丙基葡聚糖凝胶(Sephadex LH-20)柱色谱,ODS柱色谱和半制备高效液相色谱法进行分离纯化,并通过理化性质、质谱、核磁共振技术(
1
H和

结果:
2
从三叶木通正丁醇部位分离并鉴定出14个化合物,分别鉴定为木通皂苷B(

Objective:
2
To study the chemical constituents from
n
-butanol extract of
Akebia trifoliata
caulis.
Method:
2
The 100 kg caulis of
A
.
trifoliata
was extracted with 75% ethanol (EtOH) for three times by heating reflux. These 3 extracts were decompressed and concentrated
and then dissolved in water. The solvent was successively extracted with dichloromethane
ethyl acetate and
n
-butanol. The chemical constituents from the
n
-butanol fraction were isolated by macroporous
silica gel
sephadex LH-20 and ODS columns
and semi-preparative high performance liquid chromatography
and their chemical structures were determined through MS
NMR analysis (
1
H and
13
C-NMR) and spectroscopic data from literatures.
Result:
2
Totally 14 compounds were isolated and identified as mutongsaponin B(
