目的:通过正交实验来优选杏桔合剂的最佳提取工艺,并完善质量标准体系。方法:采用正交试验设计法,以苦杏仁苷的含量为指标,综合考察了乙醇浓度、溶剂用量、提取次数3个因素对提取效果的影响,对合剂提取工艺进行筛选,结果确定了杏桔合剂的提取工艺:加水10倍量,提取2次,每次1 h。结论:优选得到的工艺稳定、可行。
OBJECTIVE: To optimize the extraction process of apricot orange by orthogonal experiment and improve the quality standard system. Methods: Using orthogonal test design method, taking the content of amygdalin as an index, the effects of three factors including ethanol concentration, solvent dosage and extraction times on the extraction were comprehensively investigated, and the extraction process of mixture was screened. The results showed that apricot Mixture extraction process: 10 times the amount of water, extracted 2 times, each 1 h. Conclusion: The optimal process is stable and feasible.
