摘要: Dioscorea opposita Thunb. has been used as health food and herbal medicinal ingredients in traditional Chinese medicine. In this study, the total DNA of D. opposita Thunb. was extracted using an improved cetyltrimethylammonium bromide (CTAB) method, and the extracted DNA was further used for random amplified polymorphic DNA (RAPD) reaction system by design of the L-16 (4(4)) orthogonal diagram. The results showed that the improved CTAB method can be used to isolate high-quality and high-concentration DNA, and the optimized protocol can overcome the instability of RAPD reaction system. The knowledge stated here can be used to study the genetic diversity of D. opposita Thunb.
