Heterodon specimens as successfully extracted by the steps of removing the formaldehyde through improved gradual dehydration first and extracting the genomic DNA by the traditional phenol-chloroform method then. After primers designed, the PCR amplification was carried out, and a 205bp of the control region of mtDNA from all of the ten specimens was successfully amplified.
