[Differential textual research and analysis on the evolution of fritillaria species in successive dynasties].

Rhizoma bolbostemmae was the earliest applied fritillaria species during the period of pre-Qin to Han Dynasties in China. In the period of Wei-Jin, the fritillaria species presented diversities, with Zhejiang-fritillary also appeared for the first time. During the period of the Tang Dynasty to late Ming Dynasty, the fritillaria species kept expanding, Fritillaria hupehensis and Zhejiang-fritillary were deemed authentic species all the time. To the end of the Ming Dynasty, Fritillaria hupehensis withdrew from the stage of history gradually, Fritillaria cirrhosa came into being and then Fritillaria cirrhosa and Zhejiang-fritillary both appeared and became two important species of medicinal fritillarias after late Ming dynasty until today. In the period of the Qing Dynasty, the cognition of Fritillaria cirrhosa, Zhejiang-fritillary and rhizoma bolbostemmae became more and more clear. The fritillaria species continued to expand, and counterfeit and local species began to appear in large numbers.
