Abstract:

The methods of molecular identification, morphology identification and microscopical identification were used to study the pharmacognosy of Bidens procera L.C.Xu ex X.W.Zheng. By determination of the ITS sequence of DNA, Bidens procera L.C.Xu ex X.W.Zheng was confirmed as Bidens L.. And the morphology and the microscopic identification of its stems and leaves were described and recorded in detail. The method established in this study will provide a reference for the identification and development control of Bidens procera L.C.Xu ex X.W.Zheng.

Key words: morphology identification, Bidens procera L.C.Xu ex X.W.Zheng, molecular identification, microscopic identification
