Suitable DNA Barcoding for Identification and Supervision of Piper kadsura in Chinese Medicine Markets.

ABSTRACT: Piper kadsura is a vine-like medicinal plant which is widely used in clinical treatment. However, P. kadsura is often substituted by other materials in the markets, thereby causing health risks. In this study, 38 P. kadsura samples and eight sequences from GenBank, including a closely-related species and common adulterants were collected. This study aimed to identify an effective DNA barcode from four popular DNA loci for P. kadsura authentication. The success rates of PCR amplification, sequencing, and sequence acquisition of matK were 10.5%, 75%, and 7.9%, respectively; for rbcL they were 89.5%, 8.8%, and 7.9%, respectively; ITS2 rates were 86.8%, 3.0%, and 2.6%, respectively, while for psbA-trnH they were all 100%, which is much higher than for the other three loci. The sequences were a
