【摘要】 研究采用超声波技术从紫苏中提取迷迭香酸的工艺条件.用正交实验L18(37)优化,硫酸亚铁比色法测定迷迭香酸得率.确定的最佳工艺条件:40%乙醇为提取剂,料液比为1∶60(m/V),超声波输出功率为300W,提取时间为15min,占空比为50%,迷迭香酸提取得率为1.146%.

【Abstract】 The extraction of rosmarinic acid from Perillae by ultrasonic technology were studied.We optimized the extraction factors with L18(37) orthogonal experimental design,and the ratio of rosmarinic acid analysis with FeSO4 method.The results showed that the optimal extracting technological conditions were as follows: extraction solvent was 40% alcohol,the mass ration of material to liquor was 1∶60(m/V,)supersonic power was 300W,extracting time was 15min and duty cycle was 50%.Under this condition,the extracting rate of rosmarinic acid could reach 1.146%.
