目的：优选苦石莲胶囊提取工艺。方法采用L9(34)正交试验法，以化合物Neocaesalpin L提取率为指标，考察提取方法、乙醇体积分数、提取时间、提取次数、乙醇用量对Neocaesalpin L提取率的影响。结果最佳提取工艺为用25倍量的95%乙醇，提取2次，每次提取时间1.5 h。结论优选的工艺稳定，可为工业化生产提供依据。%Objective To optimize the extraction process of Caesalpinia Minax Capsules. Methods The extraction of Caesalpinia Minax Capsules was determined by L9 (34) orthogonal test with Neocaesalpin L extraction rate as index, and the effects of extraction method, concentration of alcohol, extraction times and frequency and the amount of ethanol added on Neocaesalpin L extraction rate were investigated. Results The optimal extraction condition was 25 folds amount of 95% ethanol, 2 times, 1.5 h each time. Conclusion The optimized process is stable, which can offer evi-dence for industrial production.
