[Pharmacognostical study on cultivated Fritillaria taipaiensis]

To study on the pharmacognostical characteristics of cultivated Fritillaria taipaiensis for providing basis for further development and research.

Botanical, macroscopic and microscopic identifications, and determination of the content of extract, total saponins and total alkaloids were carried out.

Because of various growing years, cultivated Fritillaria taipaiensis had diffferent properties,in addition to tip slightly resembling songbei's tip "embracing the moon", there were greatly different characteristics in the rest of specifications comparing with the traditional Fritillaria cirrhosa. Some were shallow conical or cylindrical, some had slightly rough surface,and some bases were constricted, bitter in taste. There were great differences in its extract and total alkaloids con-tent,and no obvious differences in the content of total saponins.

The experimental results show that the extract,total saponins and total alkaloids content are not positively correlated or relevant with the current classification of Fritillariae Cirrhosae Bulbus. To consider the medicinal appearance diameter and length, the grade classification should be based on different application requirements, and combined with the evaluation of active ingredients.
