Abstract: The PCR technology was used in the detection of plant ingredient in milk drink. Combined with pre-operation and phenol-chloroform extraction, a rapid and simple method of DNA extraction from milk drinks was found, and DNA extraction took only two hours. The quality of DNA is sufficient for PCR analysis. Moreover, 0.1% plant ingredient in milk drink can be detected by this method.
