The application of PCR analysis on the herbal medicine Moutan Cortex (Paeonia suffruticosa Andrews) was evaluated by the comparison of the genetic relationship based on the DNA sequence with Paeoniae Radix (Paeonia lactiflora Pallas) following development of specific primers. Moutan Cortex and Paeoniae Radix were distinguished through the PCR analysis based on the internal transcribed spacer (ITS-PCR) from nuclear ribosomal DNA region. The 294 bp PCR products both of Moutan Cortex and Paeoniae Radix was amplified by MIF1 and MIR1. And a Moutan Cortex specific 225 bp PCR amplification product was amplified by MIF2 and MIR1 primers. The 225 bp sequence could be successfully amplified from Mortan Cortex of dried herbal preparations. PCR analysis based on ITS (ITS-PCR) may be an efficient tool for the discrimination of Moutan Cortex.
