摘要
目的:对太白贝母栽培品进行生药学研究,为该药的进一步研究与开发利用提供依据。方法:采用生药学常规方法进行原植物鉴定、性状鉴定、显微鉴定及浸出物、总皂苷与总生物碱的含量测定。结果:太白贝母栽培品因生长年限不同性状差异较大,除松尖略似松贝"怀中抱月"外,其余各规格在性状特征上均与传统川贝母差异大,多扁圆锥形或圆柱形,体表稍粗糙,基部隘缩,味苦。其浸出物含量、总生物碱含量相差较大,总皂苷含量无明显差异。结论:实验结果显示浸出物、总皂苷、总生物碱的含量与川贝母现行的等级划分不成正向相关关系或不相关。建议等级划分在考虑药材外观性状直径、长短时,应根据不同的应用要求,结合有效成分的含量测定进行评价。
Objective：To study on the pharmacognostical characteristics of cultivated Fritillaria taipaiensis for providing basis for further development and research.Methods：Botanical,macroscopic and microscopic identifications,and determination of the content of extract,total saponins and total alkaloids were carried out.Results：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 content,and no obvious differences in the content of total saponins.Conclusion：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.
