| Abstract: | - The method of microwave extraction combined with orthogonal experiment is adopted and the optimizing extraction conditions of catechin is studied. in this paper. - It is mensurated by orthogonal experiments. - The best extraction conditions of catechin are:microwave power 400W,alcohol concentration 60%,extraction time 70 second,the ratio of material to liquid is 1∶20;the yield of catechin is 8.9%,and the content is 26.6%,which are higher than that by tea polyphenols methods. |
