This article selected one judicial identification case of illegal acquisition of A lseodaphne hainanensis as an example, which is a plant that intensively protected in China. In the premise of feasible identifying technique, we conducted a molecular identification on the object logs using ITS sequence analysis. The DNA of the object logs are extracted under the CTAB method and purified, then a PCR expansion of the ITS rDNA is conducted. Af-terwards the PCR positive product is cloned and sequenced, on the results of which a Blast analysis is done and phylogenetic tree is construced. The results...
