Investigation of Decoction Process of Digda-4 Decoction
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:
2
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:
2
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:
2
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.
