The main composition of Gypenosides

Of Gypenosides, a total of about 140 kinds, respectively named Gypenosides, some of Rb1 ginsenosides, Rb3 respectively, Rd, and ginseng diol, 2 alpha hydroxy ginseng diol, alpha 2, 19 - dihydroxy - 12 - deoxidization ginseng diol (see article "13001, ginseng") for structural formula. Therefore, its composition content determination and finished product standard, are also in Rb1 ginsenosides how much as standard. The other containing rutin flavonoids (determination of rutin as the standard), alpha bo's sterol, pokeweed flavin, etc. Gypenosides (GPS) is the basic chemical structure of darma alkanes tetracyclic triterpene, c3 and C20.

The process has a short production cycle, low cost, high product purity and yield higher advantages. Chinese medicinal quality goods gynostemma Pentaphyllum () on the whole, the active ingredients of medicinal gynostemma total glycosides content is higher.
