Abstract:
Objective To study the genomic DNA extraction from Rhizoma Coptidus and optimization of RAPD reaction system. Methods Different methods, i.e. phenol method, CTAB method, low pH extraction medium with high salt, were used to genomic DNA extract from Rhizoma Coptidus. The DNA samples obtained by the above methods were tested by agarose gel electrophoresis and ultraviolet spectrometer. Results CTAB Method was considered to be an optimal technique. Based on the genomic DNA extracted by CTAB method, a reaction system suitable for Rhizoma Coptidus was established, that is, 25 ?L amplification reactions system containing 1?PCR buffer, 2 mmol/L Mg 2+, 100—150 ?mol/L dNTP, 20 ng primer, 40 ng template DNA, and 1 U Taq DNA polymerase. Conclusion CTAB Method and RAPD reaction system can be used to RAPD analysis in Rhizoma Coptidus.
