  1. Extraction process:

         Adopt new technology of extracting tea saponin, water extract-alcohol precipitation is the law. Water extraction process of the optimum technological conditions for leaching temperature 60 °C, liquid-solid ratio 10:1, 2 h, leaching time, leaching times 3 times. Alcohol sink back in water extraction and the optimal conditions is obtained by experiment is 90% ethanol concentration, ethanol and concentrate volume 4:1, alcohol sink temperature 75 °C, alcohol sink time 2. 5 h, and under the condition of the water of water extract-alcohol precipitation and the method, the method of water extract-alcohol precipitation that extraction yield of 95. 2%, the purity was 69. 9%, improves the purity, is advantageous to the subsequent refining processing.

2.Our Advantage:

a. Small order is acceptable;

b. Free sample for you;
