ABSTRACT
The ITS2 barcode was used to accurately identify Albiziae Cortex, Albiziae Flos and their adulterants in this study. A total of46 samples from Albiziae Cortex, Albiziae Flos and their adulterants were collected. The ITS2 regions were amplified and sequenced. Sequences were assembled using the CodonCode Aligner. The genetic distances of ITS2 region were calculated using MEGA 5.0. BLAST1, nearest distance and phylogenetic tree (NJ-tree) methods were used to assess the identification efficiency of the ITS2 barcode. The results revealed that the intraspecific genetic distances of Albizia julibrissin were lower than the interspecific genetic distances between A. julibrissin and its adulterants. The identification efficiency of ITS2 barcode using BLAST1 was 100%. The NJ-tree showed that A. julibrissin and their adulterants can be easily differentiated according to their monophyly. The ITS2 barcode is suitable to be as a barcode to identify Albiziae Cortex, Albiziae Flos and their adulterants.
