目的:研究复方田基黄胶囊中总蒽醌的最佳提取工艺。方法:采用回流提取法,以紫外分光光度法测定提取液中总蒽醌含量为指标,以氯仿用量、回流时间、硫酸用量、萃取次数为考察因素,采用L9(34)正交实验法优选复方田基黄胶囊的最佳测定方法。结果:最佳条件为:氯仿用量为30mL,回流时间为120min,硫酸用量为20mL,萃取次数为3次。结论:该测定方法稳定,安全,简便易行。
Objective: To study the best extraction technology of total anthraquinone in compound Tianjihuang capsule. Methods: The content of total anthraquinone in the extract was determined by UV-Vis spectrophotometry. The factors such as the amount of chloroform, the reflux time, the amount of sulfuric acid and the number of extraction were used as the investigation factors. The orthogonal test was used to optimize the compound Tian Ji Huang capsule the best determination. Results: The optimal conditions were as follows: the amount of chloroform was 30mL, the reflux time was 120min, the amount of sulfuric acid was 20mL and the number of extraction was 3 times. Conclusion: The method is stable, safe and easy to operate.
