| Abstract: | The microwave-assisted extraction technologies of shikimic acid from pine needle are studied, the influences of microwave temperature, ratio of liquor, microwave power, ethanol concentration and microwave time on shikimic acid extraction rate are investigated, and the technological conditions are optimized through orthogonal test. The results show that the optimum conditions are as follows： microwave temperature 35 ℃, ratio of material to liquor 1 ： 20（g/mL）, microwave power 550 W, ethanol concentration 350/00, and microwave time 90 s. The extraction rate of shikimic acids can reach 11. 312 mg/g in the optimum conditions. |
