ABSTRACT
Objective:To optimize the decoction process of Digda-4 decoction(DGD-4D), and provide reference for the standardization study of decoction of Mongolian medicine decoction. Method:Taking DGD-4D as model drug, different decoction methods of Mongolian medicine were compared, HPLC was used to determine contents of aesculetin, geniposide, picroside Ⅰ and picroside Ⅱ.On the basis of single factor tests, central composite design-response surface methodology was adopted to optimize the decoction process of DGD-4D with transfer rates of 4 components and dry extract rate as indexes, regression model fitting was carried out by Design-Expert 8.0.6 software, prediction model of process parameters was established, and the optimal process was verified. Result:The optimal decoction condition of DGD-4D was determined to be adding 40 times the amount of water and decocting for 17 min, decocting once.Transfer rates of aesculetin, geniposide, picroside Ⅰ, picroside Ⅱ and dry extract rate were 70.01%, 94.11%, 61.23%, 92.32%, 32.89%, respectively. Conclusion:The optimum decoction process of DGD-4D is established, it has important reference significance for excavating, sorting, improving the level of Mongolian medicine preparations and ensuring the consistency of their clinical efficacy.
