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 the pharmacognosy of Fritillaria parenterali cultivars and provide basis for the further research, development and utilization of this medicine. Methods: The methods of crude drug identification, traits identification, microscopic identification and content of total saponins and total alkaloids were determined by the routine methods of crude pharmacy. Results: The results showed that there were significant differences in the traits of Taibai Fritillaria cultivars due to their different growth years. Except pine needles, Flat conical or cylindrical, body surface slightly rough, narrowed base, bitter taste. The content of its extract, total alkaloids content difference, the total saponin content no significant difference. Conclusion: The experimental results show that the contents of extract, total saponin and total alkaloids are not positively or irrelevant to the current grading of Fritillaria cirrhosa. Proposed classification In considering the appearance of medicine diameter, length, should be based on different application requirements, combined with the determination of the content of active ingredients for evaluation.
