[Fingerprints identification of Gynostemma pentaphyllum by RAPD and cloning and analysis of its specific DNA fragment].

RAPD technique can be used for the accurate identification of Gynostemma pentaphyllum and its counterfeit goods Cayratia japonica. Besides, these specific DNA sequences for Gynostemmna pentaphyllum in this study are useful for the further research on identification of species and assisted selection breeding in Gynostemma pentaphyllum.
