| Abstract: | Objective:to search for the best condition of combined extraction for flavonoids and glycyrrhizic acid in glycyrrhiza by using ultrasonic-assisted method and determine their contents. Methods: using orthogonal design, the effects of ultrasonic power, ultrasonic time, extraction temperature and solide/liquid ratios(each for 3 levels) were considered, the comprehensive evaluation was guided by the content of total flavonids and glycyrrhizic acid determined by spectrophotometer. Results: Optical condition was as follow, ultrasonic power is 1 000 W,ultrasonic time is 75(25,25,25)min,extraction temperature is 40 ℃,solide/liquid ratios is 1∶8. The flavonoids content is 3.612%, the glycyrrhiza acid content is 9.820%. |
