Progress in Researches on Gynostemma Pentaphyllum Polysaccharides and Their Bioactivities

Gynostemma pentaphyllum is one of Chinese natural characteristic resources. The results of researches in recent years have shown that Gynostemma pentaphyllum 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 pentaphyllum polysaccharides mainly in composition,extraction process,physiological action and use prospects.
