Chinese dendrobe plant and its medicinal materials DNA molecular diagnosis method

On the basis of established complete sequence data base of r DNA ITS area of the Chinese dendrobium plant the plant or medicinal materials sample to be detected can be undergone the processes of total DNA extraction, PCR amplification, PCR product purification, DNA sequence determination and analysis, whe the DNA sequence of the plant or medicinal material to be detected is identical to that of some dendrobium plant in the data base, it is said dendrobium. According to the data base it can implement high-specificity PCR discrimination of dendrobium candidum plant and its medicinal materials.
