Abstract

The invention belongs to the technical field of traditional Chinese medicine species identification, and provides a polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP) method for identifying dinodon rufozonatum. The sequence of the premier is DK1-CO1:5'-CAA CTA ACC ACA AAG ACA TCG G-3', DK1-CO2:5'-CTT CTG GCT GGC CGA AAA ATC A-3'; and the characteristic DNA base sequence of dinodon rufozonatum is 5'-GTGCAC-3', which can be recognized and cut by restriction endonuclease APaL I. The identification comprises the following steps: extracting the DNA of a sample; using premiers DK1-CO1 and DK1-CO2 to carry out PCR amplification; using restriction endonuclease APaL I to digest the PCR products; carrying out agarose gel electrophoresis to obtain the analysis result; and comparing the analysis result with the PCR-RFLP characteristic result of dinodon rufozonatum to judge whether the provided sample is dinodon rufozonatum or not. The invention also provides a kit for the identification method. The identification is accurate, rapid, and reliable, and is capable of effectively identifying dinodon rufozonatum from other snakes.

Description

technical field [0001] The invention belongs to the technical field of identification of varieties of traditional Chinese medicines, and in particular relates to a primer, a PCR-RFLP method and a kit for identifying red chain snakes. Background technique [0002] Red chain snake (Dinodon rufozonatum) is a reptile of the genus Dinodonidae. It has anti-inflammatory, sedative hypnotic, and anti-convulsant effects. It is used for rheumatoid arthritis, detoxification and sores, general pain, chronic fistula, ulcers, and Ringworm etc. The red chain snake is a common counterfeit of the money white snake. With the increase in the price of medicinal materials and the gradual reduction of resources in recent years, more and more red chain snakes are being used as money snakes. At present, 50% of the money snake products on the market are counterfeit products from the red chain snake, and it is difficult to identify the two from the morphological characteristics. Finding a fast and ...
