Resumo: | ABSTRACT The carapace of the tortoise Chinemys reevesii is an ingredient of “Guijia”, a traditional Chinese medicine. However, C. reevesii is difficult to raise in aquaculture and is rare in the wild. Counterfeit tablets are made from carapaces of other species. In addition to C. reevesii, other species including Mauremys sinensis, Indotestudo elongate and Trachemys scripta have been used in Plastrum Testudinis as well. After processing, these carapaces are difficult to identify on the basis of morphological characteristics, which impedes law enforcement. Our study used DNA barcoding technology to identify C. reevesii and its substitutes. We extracted concentrated genomic DNA for PCR amplification. Based on the analysis of 61 full-length COI sequences, we designed four pairs of mini-barcode primers: Tu-A, Tu-B, Tu-C and Tu-D. The Tu-B primers sequenced genomic DNA with a success rate of 76.47%, and the Tu-D primers sequenced genomic DNA with a success rate of 88.24%. The identification efficiency of these two mini-barcodes was 70.59% and 64.71%, and the overall identification efficiency was approximately 76.47%. Similarly, a set of mini barcode systems was generated, which may provide an effective and low-cost method for the identification of authentic tortoise shells. |
