| Abstract: | The content of the total flavonoids was computed with rutin as standard substance, and the influence of different factors and levels on the ultrasonic extraction technology were investigated by means of simple factor experiment and orthogonal experiment. As the results showed that the best extraction condition were as follows： adding 70 times volume of 40 % alcohol, ultrasonic extraction for 45 min with 28 kHz to extract the flavonoids ultrasonic working frequency. The extraction method was appropriate, simple and feasible. It was an ideal way of cortex llicis rotundae. |
