Abstract

Owing to the high pharmacological and economic value, the Chinese medicinal herbs: Paris polyphylla var. yunnanensis, Polygonatum kingianum and Bletilla striata, whose quality has been damaged by their adulterants. In this study, the allele-specific diagnostic PCR method was used to identify three herbal medicines and their adulterants. And the nuclear gene ITS2 sequence and chloroplast gene psbA-trnH sequence, as international common barcode sequences, are widely used in the molecular identification of medicinal plants. Therefore, three pair of specific PCR primers were respectively designed according to the sequence of Paris polyphylla var. yunnanensis on the ITS2, Polygonatum kingianum and Bletilla striata on the psbA-trnH, using Primer 5.0. And these specific identification primers could amplify special bands respectively at 130bp, 331bp and 508bp, while adulterants could not amplify the bands. The results showed that this method could respectively distinguish three herbal medicines and their adulterants. And after many experiments, the method had good repeatability. The allele-specific PCR identification method established in this study is easy to operate and fast in identification. This method can distinguish three kinds of traditional Chinese medicines and their adulterants, which provides a reference for the identification of other traditional Chinese medicines, so as to further protect the Chinese herbal medicine industry from economically motivated adulteration.
