title: [The extraction, purification and assaying of Gynostemma pentaphyllum polysaccharides].
abstract: By orthogonal design, and considering extracting efficiency and cost, optimizing the extract method of Gynostemma pentaphyllum polysaccharides. We purified the crude Gynostemma pentaphyllum polysaccharides initially, and assayed the polysaccharides content of Gynostemma pentaphyllum polysccharides. The content of Gynostemma pentaphyllum polysaccharides was sigificantly higher than the predecessor. It would provide conditions for the deep exploitation of Gynostemma pentaphyllum.
