摘要(Abstract):

[Objectives] To identify ITS2 barcode of Lablab Semen Album and its adulterants,and provide a new method for the identification of Lablab Semen Album. [Methods] The ITS2 sequence was amplified by PCR and sequenced bi-directionally. After splicing by Codon Code Aligner,the data were processed with the aid MEGA software to construct the cluster dendrogram( neighbor-joining,NJ tree). [Results]The ITS2 sequence of Lablab Semen Album had length of 218 bp; the constructed cluster dendrogram indicated that all species were monophyletic and could be distinguished from other species. [Conclusions] The ITS2 barcode can be used for rapid identification of Lablab Semen Album and its adulterants and this experiment further verified that DNA barcode technology is effective in identification of traditional Chinese medicines.
