绞股蓝多糖及其生物活性研究进展

绞股蓝是我国天然的特色资源,近年来研究发现绞股蓝多糖是绞股蓝中的主要活性成分之一。绞股蓝多糖有免疫调节、抗肿瘤、抗氧化、抗病毒、降血糖、降血脂、抗辐射等作用,对机体的毒性很小,现已开发了许多绞股蓝制品,如绞股蓝茶、皂甙片、冲剂、胶囊、口服液、糖丸等,另外还有作为绞股蓝饮料、运动饮料及可乐和啤酒等食品的添加剂。主要对绞股蓝多糖的组成、提取工艺、生理作用和应用前景进行综述。

Progress in Researches on Gynostemma Pentaphyllum Polysaccharides and Their Bioactivities

Gynostemma pentophyllum is one of Chinese natural characteristic resources. The results of researches in recent years have shown that Gynostemma pentaphyUum polysaccharides, as the major active components in Gynostemma pentaphyllum, have immunoregulatoty, anti-tumor, anti-oxidation, anti-virus, blood sugar lowering, blood fat reducing and radiation-resistant effects but little toxicity. At president, a lot of Gynostemma pentaphyllum products have been launched, including Gynostemma pentaphyllum tea, tablet, instant powder, capsule, oral liquid, pill, etc. In addition, there are additives made from Gynostemma pentaphyllum for use in beverage, sports drink, cola and beer. A summary was carried out on Gynostemma pentaphyUum polysaccharides mainly in composition, extraction process, physiological action and t~se prospects.
