Objective: To optimize extraction technology of Penthorum chinense. Method: With extraction amount of quercitrin as index
influence of ethanol amount
extraction time
extraction times and ethanol concentration on extraction technology was investigated by orthogonal test.The content of quercitrin was determined by HPLC. Result: Extration times had significant effect on extraction technology of P. chinense
optimum extraction technology was as following:extracted 2 times with 10 times the amount of 80% ethanol
0.5 h per time. Conclusion: This optimized extraction process was stable and feasible.
