| Abstract: | Taking the stems of Tieguanyin tea as raw material, and using ultrasonic extraction, choosing the best extraction conditions through the comparison on extraction rate of tea saponin of tea stems in the concentration, liquid feed ratio, ultrasonic intermittent cycle, working time and other factors. The results showed that： In the extraction condition of ultrasonic power in 700 W, with 80% ethanol as extraction solvent, liquid feed ratio 4 ： 1, pH 10. 0, ultrasonic intermittent cycle was turn on one second and turn off 3 seconds, in work time 20 minutes, the highest rate of tea saponin in tea stems is 10. 75%. |
