目的:优选双子肠溶胶囊中决明子的最佳提取工艺。方法:采用L9(34)正交试验,以出膏率和大黄酚、橙黄决明素的提取率为指标,以乙醇浓度、料液比、提取时间和提取次数为考察因素筛选双子肠溶胶囊中蒽醌最佳乙醇提取工艺条件。结果:双子肠溶胶囊中蒽醌最佳提取工艺为以70%乙醇,加醇量6倍,提取1次,1.5 h。结论:经过验证试验该双子肠溶胶囊中决明子的提取工艺稳定、简便、合理、可行。
Objective: To optimize the extraction process of cassia seed in Gemini enteric capsule. Methods: L9 (34) orthogonal test was used to determine the rate of ointment and the extraction rate of chrysophanol and orange cassia to take the ethanol concentration, the ratio of solid to liquid, the extraction time and the extraction times as the screening factors Optimum ethanol extraction conditions of anthraquinone. Results: The optimal extraction process of anthraquinone in Gemini enteric-coated capsules was as follows: 70% ethanol, 6 times alcohol, 1 time, 1.5 h. CONCLUSION: The extraction process of cassia seed in this Gemini enteric-coated capsule has been proved to be stable, simple, reasonable and feasible.
