Optimization of Water Decocting Extraction Procedures for Ganyankang Capsules with Orthogonal Design / 中国药师

ABSTRACT

Objective: To optimize the water decocting extraction procedures for Ganyangkang capsules by orthogonal design. Methods:Using the extraction yield and emodin content as the indices, the optimal extraction conditions for Ganyankang capsules were studied by L9(34) orthogonal test. Results:The influencing order of the factors was B>A>C (Aextracting time, Bextracting du-ration, Cadded water volume) . The optimal preparation conditions were A3 B3 C2 , i. e. adding 10-fold water, decocting extracting 3 times with 2 hours each time. Conclusion:The optimum water decocting extraction procedures is rational and feasible. It can be used in the real preparation.
