| Abstract: | Objective To optimize the conditions of ultrasonic extraction of Pteris semipinnata L.Methods The four factors-alcohol content(A),ultrasonic time(B),ultrasonic times(C) and solvent volume(D) were investigated by L9(34) orthogonal design,and the content of 5F were defined as the standard index.5F was determined by TLC-Scanning.Results A2B2C3D3 was the optimum condition of the ultrasonic extraction,which was adding 10 times amount of 70% alcohol and extracting for 30 min(totally extracting for 3 times).Conclusion The optimized process is stable and available. |
