摘　　要：使用不同乙醇体积分数、微波时间、微波功率、料液比等对咸草植物体中总黄酮提取率的影响进行探讨,并通过正交设计实验,探讨咸草植物体总黄酮提取的最佳提取条件,结果表明,最佳微波提取条件是:60%乙醇,微波时间20 s,功率540 W,料液比(g∶mL)为1∶70,咸草总黄酮质量分数为17.02%.The effects of ethanol concentration, extracting time, power of microwave oven and material：liquid ratio （g：mL） on extraction efficiency of flavones in Cyperus malaccensis Lam. var brevifolius Bocklr. were investigated. Also, the optimal extraction condition by using the orthogonal test was discussed. Results indicate, the optimum microwave-assisted extraction condition is ethanol concentration of 60%, extraction time of 20 s, the power of microwave oven of 540 W and material ： liquid ratio of 1 ： 70, the total flavones content in Cyperus malaccensis Lam. var brevifolius Bocklr. is 17.02% on this condition.
