Pharmacognosy Identification of Gentiana farreri Balf.f.

Objective：To establish pharmacognostical methods of Gentiana farreri Balf.f..Methods：The original plant,macroscopical,microscopic and physicochemical identification were used to authenticate this crude drug,and the identification characteristics were studied.Results：The results showed that there were moniliform incrassated epidermal cells,tentacle,petal mastoid cell and style fragment in the power;the fluorescent spot with the same color at the corresponding position of samples and controls has a good reproducibility.Conclusion：This study will provide theoretical basis for the pharmacognosy identification and further application of the plant.
