目的优选红杞胶囊的最佳提取方法。方法以红景天苷的含量为指标,考察加水量、提取次数和煎煮时间3个因素对有效成分提取的影响。通过正交设计试验筛选提取红杞胶囊的最佳提取工艺。结果影响红景天苷提取的主次因素为提取次数>煎煮时间>加水量。最佳回流工艺为:用10倍量水,提取3次,每次3 h。结论通过正交设计试验优选得到的红杞胶囊提取方法可行,该方法简单,容易操作,工艺过程简单稳定可靠。
Objective To optimize the extraction method of Hongqi capsule. Methods The content of salidroside was taken as an index to investigate the effects of three factors on the extraction of active ingredients, such as water addition, extraction times and boiling time. Orthogonal design test to screen and extract the best extraction process of red capsule. The main factors affecting the extraction of salidroside extraction times> boiling time> water. The best reflux process: with 10 times the amount of water, extracted three times, each 3 h. Conclusion Orthogonal design test obtained by the red bayberry capsule extraction method is feasible, the method is simple and easy to operate, the process is simple and stable and reliable.
