目的:优化浙贝母中总生物碱提取工艺。方法:以总生物碱含量为指标,采用酸性染料比色法测定浙贝母总生物碱含量,以乙醇用量、乙醇浓度、回流时间为主要影响因素开展正交试验,以回流次数单因素考察优化提取工艺。结果:最佳提取工艺为70%乙醇,6倍量溶媒,提取2次,每次2 h。结论:所优选出的提取工艺方法合理可行,稳定可靠。

[Abstract]
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.
