Objective: To optimize ethanol extraction process of Notoginseng Radix et Rhizoma in compound Naoqing capsules. Method: Orthogonal test was adopted to investigate effects of the concentration and amount of ethanol
extraction time and times on ethanol extraction technology of Notoginseng Radix et Rhizoma with yield of panax notogingseng saponins and notoginsenoside R1 as comprehensive evaluation index. Result: Optimum extraction conditions were as follows:extracted 3 times with 8-fold 75% ethanol
1 h each time. Conclusion: This optimized process was stable and feasible
it could provide a reference for further development of compound Naoqing capsules.
