Abstract
Cervi Parvum Cornu has been widely used as an agent in commercially available tonic medicines. The establishment of the method for the identification of each agent, especially crude drugs in formulations, is very important from the viewpoint of the quality control of drugs. In this paper, we reported the examination on the extraction method of DNA from the formulations, and also on the PCR method using four sets of primers, amplifying the DNA fragments of the regions of 12S rRNA and/or cytochrome b genes. The same size of DNA fragments as in the Cervi Parvum Cornu reference sample were found in all PCR products obtained from four commercial tonic medicines investigated. Therefore, it was confirmed that Cervi Parvum Cornu was contained in all the tonic medicines used. The PCR method was found to be a useful method for the identification of Cervi Parvum Cornu in tonic medicines and the DNA fragments amplified by the PCR method was clarified to be also helpful materials as index constituents for Cervi Parvum Cornu.
