目的:优选复方红景天颗粒的提取工艺。方法:采用比较试验法和正交试验法,对复方红景天颗粒主要成分的水提取工艺进行优选,以HPLC测定红景天苷提取量及浸膏得率为考察指标,对提取次数、浸泡时间、加水量、提取时间等因素进行优选。结果:最佳提取工艺为浸泡0.5 h后,提取2次,第1次加10倍量水提取2 h,第2次8倍量水提取1 h。结论:复方红景天颗粒的水提取工艺合理、简单易行。

Objective： To optimize extraction technology of compound Hongjingtian grain. Method： Water extraction technology for main component of compound Hongjingtian grain was optimized by contrast test method and orthogonal test method. Took yield of extract and extraction yield of salidroside as indexes to optimize extraction times, soaking time, water volume, extraction time and other factors. Result： Optimum extraction technology was soaked 0.5 h, extracted 2 times, first time extracted 2 hours with 10 times the amount of water, second time extra...
