小根蒜多糖的分离纯化及其抗氧化活性研究

The Study On Extraction,Purification and Antioxidative Activity of Polysaccharides From Allium Macrosttemon Bge

小根蒜是一味传统的中药,为百合科植物小根蒜Allium macrosttemon Bge.或薤Alliumchinensis G.Don的干燥鳞茎。性味辛、苦、温,有温中通阳,理气宽胸,通阳散结之功效。其原植物除入药外还可食用。现代研究证明,小根蒜具有抗氧化、防治动脉粥样硬化等作用。小根蒜在我国分布广泛,是一种具有很大开发潜力的植物。小根蒜中已分离得到挥发油、含氮化合物、前列腺素等化学成分,但小根蒜多糖的研究还不深入。本文主要介绍小根蒜及其多糖的提取工艺、分离纯化及对纯化组分的体外抗氧化测定。

Allium macrosttemon Bge. is a traditional Chinese native medicine, it is dry bulb of lilybranch plant Allium macrosttemon Bge. or Allium chinensis G.Don. It has the characteristic of spicy, bitter, warm and the effect of warm center passes pasitive, regulates the flow of vital energy the wide chest, passes positive relieves congestion. Its original plant not only is the medicine, but also can be edible. Research proves,Allium macrosttemon Bge. has the effect of anti-oxidation,preventing and controlling atherosclerosis. Allium macrosttemon Bge.is distributed extensively in our country, and its resource is abundant.It has great potentiality to be exploited. Chemical compositions such as the volatile oil,soap glucoside,compound containing nitrogen, the prostaglandin and so on have been separated from Allium macrosttemon Bge, but there are few reports on polysaccharide from Allium macrosttemon Bge. In this paper, we introduce the way of extraction, separation,purification, components, propertieing of polysaccharides from Allium macrosttemon Bge. And prospect future appropriate of Allium macrosttemon Bge.
