Abstract:The experiment was conducted to establish a rapid and reliable molecular identification method for Blumea balsamifera DC. By genomic DNA extraction method, we screened B.balsamifera and its adulterants, designed primers with the specific loci of B.balsamifera, and optimized the amplification conditions of PCR. We detected the PCR products by fluorescence reaction. The alkaline lysis method of extracting genomic DNA was more appropriate for B.balsamifera. It could specifically amplified by primers of tDNA, and its products were green fluorescent by fluorescence detection. While, its adulterants were non-reaction occurring. This method simplified operation steps and saved time with accurate result, and it could be served as identification method for B.balsamifera.
