摘要: 为更好地开发利用巴戟天寡糖,对巴戟天药材的寡糖进行分离纯化,并鉴定其结构。巴戟天药材粉末先采用水浴回流得到巴戟天水提浸膏,再经过活性炭柱色谱分离得到巴戟天寡糖部位粗提物,最后经过凝胶纯化系统两次以及制备液相分离得到八种寡糖,包括蔗果三糖、蔗果四糖、蔗果五糖、蔗果六糖、果果三糖、果果四糖、果果五糖和果果六糖。对得到的八种寡糖单体分别进行纯度检验,并通过高分辨质谱、红外光谱和核磁共振波谱对单体结构进行了鉴定。

Abstract:

In order to better exploit and utilize oligosaccharides from Morinda officinalis How.,oligosaccharides from M. officinalis were isolated and purified from the herb powder of M. officinalis.The herb powder of  M. officinalis was first extracted by water bath reflux extraction to obtain the water extract part,and then separated by activated carbon column chromatography to obtain crude extract of oligosaccharide.Finally,eight oligosaccharides including kestose,kestostetraose,kestopentaose,kestohexaos,inulotriose,inulotetraose,inulopentaose and inulohexaose were obtained by twice preparation by gel purification system and once preparation by preparative liquid chromatography.The purity of the eight oligosaccharide monomers was tested by liquid chromatography,and their structures were identified by high resolution mass spectrometry,infrared spectroscopy and nuclear magnetic resonance spectroscopy.

Key words: Morinda officinalis How., oligosaccharides, separation and purification, structural identification
