Abstract:
Objective To ascertain the optimum condition for extracting Rhizoma polygoni cuspidati and Radix angelicae sinensis with alcohol. Method With extract yield and the amount of polydatin as index,the primary factors of affecting the extraction were optimized. Result The optimum extraction condition was as follows:taking 60% alcohol as solvent,the meterials were refluxed and extracted two times with 10 and 8 times volume of alcohol for 1.5 h and 1.0 h,respectively. Conclusion The optimum extraction process provides an experimental basis for industrial production.
