摘　　要：研究了微波萃取胭脂虫红色素的影响因素,利用正交试验对微波萃取条件进行优化。确定了最佳提取工艺为微波功率为560W,微波作用时间为40s,料液比为1∶4,合适的提取次数为10次。经过10次浸提色素的得率可达42.11%。Orthogonal tests were adapted to optimize the microwave extraction process. The results showed that the optimal conditions for the extraction were obtained as follows： the ratio of material to solvent 1：4 at 560W for 40s. The extracting time was 10 under this condition. The extract was evaporated to dryness and the crude extract was obtained with the yield of 42.11%.
