Objective: To compare the effects of different kits and different methods on the extraction of genomic DNA from Tibetan patent medicine Shiliu Jianwei powder. Methods: The genomic DNA of the Tibetan patent medicine Shiliu Jianwei powder was extracted using four different commercially available kits and magnetic bead method and the adsorption column method. The effect of genomic DNA extraction was comprehensively compared with Nano Drop one, Qubit, and gel electrophoresis. Results: Four commercially available kits and two methods were used to extract the genomic DNA of the Shiliu Jianwei powder. The results showed that the adsorption column method, namely kit 3 and kit 4, was superior than the bead method using kit 1 and kit 2 in terms of the concentration of genomic DNA, the integrity of DNA fragments, and the PCR amplification effect, and economy. Conclusion: Preliminary research on the extraction effect of main stream nucleic acid extraction methods on genomic DNA of Tibetan patent medicine Shiliu Jianwei powder is performed. It is proved that under the standard method of the kit, the adsorption column method has a better extraction effect of genomic DNA, which lays a preliminary foundation for the further optimization of the extraction method.
