贝母系止咳化痰药,生物碱是其主要成分。伊贝母类的总生物碱以西贝索含量为最高。本文对原产于新疆而栽培于太白县的不同品种的贝母及野生太白贝母,用两相滴定法测定了总生物碱的含量,用薄层扫描法测定了西贝素的含量,对考察贝母的内在质量建立了分析方法。实验部分仪器及材料岛津 CS—930型双波长薄层扫描仪;微量定量毛细管(Drummond 科学公司,USA);西贝素(Sipeimine)对照品,新疆药物研究所李芳桂同志赠送。栽培贝母样品:伊贝母(Fritillaria pallidiflora
Fritillaria is an antitussive and expectorant drug, and alkaloids are its main components. The total alkaloids in the Iberotype motherfish are the highest in the Sibesol content. In this paper, the content of total alkaloids was determined by two-phase titration for the different varieties of Fritillaria sibiricus and wild Taibai Fritillaria that were grown in Xinjiang and cultivated in Taibai County. The content of Sibelin was determined by thin-layer scanning. Examine the intrinsic quality of fritillaria to establish analytical methods. Experimental instruments and materials Shimadzu CS-930 dual-wavelength thin-layer scanner; microquantity capillary (Drummond Scientific, USA); Sipeimine reference substance, presented by Comrade Li Fanggui of Xinjiang Institute of Materia Medica. Cultivation Fritillaria sample: Fritillaria pallidiflora
