Abstract

As a widely used medicinal plant, Alisma orientale is always a possible target for fraudulent labeling. The internal transcribed spacer (ITS) regions of nuclear ribosomal DNA (nrDNA) of the six species of genus Alisma were sequenced, and two variant sites were found to be specific for A. orientale. Polymerase chain reaction restriction fragment length polymorphism (PCR-RFLP) analysis and amplification refractory mutation system (ARMS) analysis were applied to the ITS region for the identification of A. orientale. A restriction site for PstI useful for PCR-RFLP analysis was detected and a pair of diagnostic primers DFZX-JB02S and DFZX-JB02X were designed for ARMS.
