Abstract:
Objective:To study the optimum extraction conditions for Yaotong granules. Methods:An orthogonal test was adopted to optimize the percolation extraction process of total alkaloids by orthogonal experiment with the yield of dry extract and total extraction rate of tetrandrine and fangchinoline as the indices. Results:The optimal extraction conditions were as follows:the medicinal materials were soaked with crude powder in 60% ethanol for 48h,then percolated at the rate of 2 ml·min-1 ·kg-1 . Conclusion:The extraction technology for Yaotong granules is simple and rapid with stable results,which can provide theoretical basis for the production of Yaotong granules.
