摘要
An effective, easy and rapid method of distinguishing Panax species is urgently needed, for traditional methods are time-consuming and inaccurate. Here, universal primer for multiplex PCR, and probes containing the 2 SNPs and an additional mismatch were designed in ITS2 region to distinguish P. ginseng and P. quinquefolius. In this system, multiplex amplification was integrated with hybridization, making the single test costing only 2-4 h. The detection sensitivity of this system reached 2 pg per reaction. Results showed the system can be applied to effectively identification of P. ginseng and P. quinquefolius.
