At the 2016 Dalian International DNA and Genomics Week Forum held recently, some scholars said that DNA molecular identification technology can be used to identify the valuable Chinese medicine Cordyceps sinensis.

Cordyceps sinensis has been used as a traditional Chinese herbal medicine for more than 500 years. In recent years, Cordyceps sinensis has been favored by more and more people as a daily health care product, and the market demand is increasing. However, due to over-excavation, wild resources have been drastically reduced. The market for sale of Cordyceps sinensis is mixed, and it is difficult to distinguish between true and false. It is urgent to strengthen market supervision.

Zhang Wenjuan, an associate researcher at the China National Institute for Food and Drug Control, said that the current Chinese Pharmacopoeia's standard regulations on Cordyceps sinensis are only "traits" and "content determination", lacking objective, accurate and specific identification criteria. At present, the common fakes that need to be identified with Cordyceps sinensis are mainly two kinds of closely related Cordyceps and artificial Cordyceps fermenting powder.

Zhang Wenjuan said, "We use DNA molecular identification technology to identify the fungi of Cordyceps sinensis and Cordyceps sinensis. According to the different components of Cordyceps sinensis and artificial Cordyceps sinensis, the DNA molecular identification technology is also used for identification. ."

Zhang Wenjuan said that the identification of Cordyceps sinensis by DNA molecular identification technology is objective, accurate and reproducible. It is suitable as a kind of authenticity identification method for quality control of Cordyceps sinensis and related products. It has good practical value and is similar. The research on DNA molecular identification methods of Chinese medicinal materials varieties provides ideas.
