Flos Lonicerae Japonicae is a traditional Chinese materia medica which has an important function in the treatment of H1N1 influenza, hand-foot-and-mouth disease (HFMD), and severe acute respiratory syndromes (SARS). However, Flos Lonicerae Japonicae and its closely related species have been misused. Therefore, it is imperative to identify them accurately. DNA barcoding is a novel molecular identification method that provides a turning point in solving the difficulty in identifying traditional Chinese materia medica using traditional identification techniques. However, the stability and accuracy of DNA barcoding need further study. The present study aims to examine the stability and accuracy of the ITS2 and psbA-trnH regions in the identification of Flos Lonicerae Japonicae and its closely related species. The results showed that both regions can stably and accurately distinguish Flos Lonicerae Japonicae and its closely related species.
