Optimization of Ethanol Extraction Process for Sisheng Granules with Orthogonal Test
Objective: To optimize ethanol extraction process of Sisheng granules. Method: L9(34)orthogonal test was adopted to investigate effects of extraction time
the amount of ethanol and ethanol concentration on ethanol extraction process with composite score of yield of verbascoside
nuciferine and dry extract as index. Result: Optimal extraction conditions were as follows:reflux extracted 2 times with 12 folds the amount of 60% ethanol
1 h per time. Conclusion: Optimized ethanol extraction process was stable and feasible
it could be extended for application in industrial production.
