In modern life, Chinese medicinal preparations are more commonly used than raw materials. It is more difficult to accurately authenticate herb ingredients in the preparations. The DNA sequence is often used to identify flora and fauna species. Nested PCR has the specificity and the sensitivity. Nested PCR and DNA sequencing methods were applied to detect herb components and to identify the botanical origin in Chinese medicinal preparations. In this paper, the identification of over twenty herbs in Chinese medicinal preparations was described.
