Traditionally, the authentication of the traditional Chinese medicines (TCM), Angelica sinensis, is based on slightly different morphological characters and complex compounds. Usually, those methods are simultaneously affected by several factors, leading to subtle and ambiguous results. In this study, the internal transcribed spacer (ITS) regions of A. sinensis and seven other Angelica species used as adulterants were sequenced. A pair of specific primers was designed from the polymorphic ITS regions to distinguish A. sinensis from the adulterants and regional substitutes. These ITS-derived primers amplified approximately 520 bp specific fragments from the adulterants, whereas no products was amplified with the DNA of A. sinensis. We tested eight... |
