目的:探讨驱铅颗粒水提工艺的条件。方法:以盐酸小檗碱含量为指标,采用高效液相色谱方法测定含量,用正交试验方法对水提进行工艺优化。结果:确定最佳工艺为A1B2C2,即药材加8倍水量,提取2次,每次1.5h。结论:选择盐酸小檗碱含量为考察指标,能客观反映出各工艺条件下的效果,高效液相色谱法具有分析准确、快速、干扰小等优点。
Objective: To investigate the conditions of water extraction process of lead removing particles. Methods: The content of berberine hydrochloride was taken as the index, and the content of berberine hydrochloride was determined by high performance liquid chromatography (HPLC). The technology of orthogonal test was optimized for the extraction of water. Results: To determine the best process for the A1B2C2, that is, herbs plus 8 times the amount of water, extracted twice, each 1.5h. Conclusion: The selection of berberine hydrochloride content as an index can objectively reflect the effect of each process conditions, high performance liquid chromatography has the advantages of accurate, fast, less interference.
