目的:利用正交试验法优化律复康处方中水提取工艺研究。方法:采用高效液相色谱法测定丹酚酸B的含量;苯酚-硫酸法[1]测定律复康胶囊水提取部分多糖含量;测定测定律复康组方药材水溶性浸出物含量(按《中华人民共和国药典》2000年版一部附录47测定)。最后由综合加权评分法[2]评定结果,以确定最佳提取工艺。结果:水提正交最佳工艺是加8倍量的水提取2次每次提取时间为1h。结论:该提取工艺合理,有效成分提取效率高。
Objective: To optimize the water extraction process of prescription of Lukukang by orthogonal experiment. Methods: The content of salvianolic acid B was determined by high performance liquid chromatography (HPLC); phenol-sulfuric acid method was used to determine the content of some polysaccharides extracted from water of Fructus Forsythiae Capsule; the content of water- People’s Republic of China Pharmacopoeia "2000 edition of an appendix 47 determination). Finally, the results of the comprehensive weighted scoring method [2] to determine the best extraction process. Results: The best water extraction orthogonal process is to add 8 times the amount of water extraction 2 times each extraction time of 1h. Conclusion: The extraction process is reasonable, efficient extraction of active ingredients.
