Extraction Technology of Total Alkaloids in Bulbus Fritillariae Thunbergii
浙贝母总生物碱提取工艺优化研究

This study was aimed to optimize the extraction technology of total alkaloids in Bulbus Fritillariae Thunbergii. Acid dye colorimetry was adopted to determine the total alkaloid, with the content of total alkaloids as index. The extraction technology was optimized by orthogonal and the single factor tests. The results showed that the optimal extract processing was 6 times volume 70% ethanol, 2 h and extracting 2 times. It was concluded that the optimal extract processing was reasonable, stable and reliable.
