Methods: The content of imperialine in the extracts was determined by thin layer chromatography scanning. 方法:应用薄层扫描法比较测定了伊贝母的不同溶剂提取物中西贝素的含量。
Objective: To compare the extraction efficiency of imperialine extracted with different solvents. 目的:比较不同溶剂对西贝素的提取效率的影响。
According to the results of determination of the three batches of test samples, the limit contents of Peimisine, Peimine, Peiminine, Imperialine and the total Alkaloid were developed. 根据测定三批中试样品结果,拟订了川贝母流浸膏中贝母辛的含量限度,三碱含量之和(贝母素甲、贝母素乙和西贝母碱)的限度及总生物碱含量的限度。
