Abstract
L9(34)orthogonal test was designed using ursolic acid as a control and the content of total saponin as a index to determine the rational extraction process.The best extraction condition was material-liquid rate 25 mL/g,irradiation time 60 s,55%microwave and 45% light-wave ratio,70% alcohol concentration.Compared with marination and ultrasonic-assisted extraction,microwave-assisted extraction was simple and accurate with good reproducibility.
