摘　　要：采用单因素分析结合正交试验的方法,研究了以表面活性剂CTMAB水溶液为提取剂,微波辅助提取山楂黄酮的工艺条件。试验结果表明,表面活性剂CTMAB-微波协同提取山楂黄酮的最佳工艺条件为:以浓度0.4%的CTMAB水溶液为提取剂,微波功率360W,料液比(g∶mL)1∶30,提取时间5m in。此工艺条件下,山楂黄酮的提取率为4.56%。表面活性剂CTMAB-微波协同提取山楂黄酮工艺条件简单,可降低提取成本,是一种有效的山楂黄酮提取方法。In this paper,single factor analysis method with Orthogonal Test was used to study the best extracting conditions of the flavonoids from Crataegus pinnatifida Bunge with assisted of the microwave and the surfactant CTMAB.The results showed：the best condition was：0.4% CTMAB as a better solvent,microwave power 360W,the solid-liquid ratio of 1 ∶30,and 5 min for extraction.Under these condition,the extraction ratio is 4.56%.The process of using surfactant CTMAB assisted microwave extraction is simple and cost effective method of extractiong flavonoids from Crataegus pinnatifida Bunge.
