目的:研究脉通胶囊中虎杖最佳提取工艺。方法:采用正交试验方法,以提取液中总蒽醌含量和虎杖苷的含量为考察指标,对影响两类成分提取工艺的因素进行了研究。结果:乙醇浓度、加液倍数对试验结果有显著影响。结论:虎杖最佳提取工艺条件为8倍量85%的乙醇,回流提取2次,每次1.5小时。
Objective: To study the best extraction process of Polygonum cuspidatum in Mailong capsule. Methods: Using orthogonal test method, taking total anthraquinone content and polydatin content in the extract as index, the factors affecting the extraction process of two kinds of components were studied. Results: Ethanol concentration and liquid times significantly affected the test results. Conclusion: The optimum extraction conditions for Polygonum cuspidatum are 8 times the amount of 85% ethanol, extracted twice, 1.5 hours each time.
