ABSTRACT
Objective To study the ultrasonic extraction technology of tyrosol in Rhodiolae Crenulatae Radix et Rhizoma;To mathematically simulate the extraction process.Methods The content of tyrosol was set as index;HPLC was used;the ultrasonic extraction process of tyrosol in Rhodiolae Crenulatae Radix et Rhizoma was optimized by an orhogonal experiment and mathematic simulation.Results The optimum ultrasonic extraction conditions were as follows80%ethanol was used as extraction solvent, the ratio of material to liquid was 135 (gmL), with the extraction time of 30 min and ultrasonic power of 240 W. In these conditions, the extracting rate of tyrosol was 0.150 1%. Compared with the heating reflux method, the extraction time should be shortened by 66.7% and the extracting rate should be increased by 12%.Conclusion The extraction method is simple and the extraction rate of effective components is high. Mathematical simulation values based on ultrasonic extraction are consistent with experiment values.
