Extraction of Tea Polyphenols in Camellia Chryscath

YAN Dong-mei LI Ren-ju QIU Hua WANG Hei LI Xin (College of Light Industry and food Engineering,GuangXi University,Nanning 530004,China)  
The extraction of tea polyphenols (TPs) in dry Camellia chryscath was studied.The influence of some key factors on TPs extraction yield was investigated and the optimal ethanol concentration,solid-liquid ratio,microwave power,microwave heating time,dipping time under normal temperature before and after microwave treatment were found to be 30%,1:30,500 w,40 s,20 min and 1 h,respectively. Under the optimized extraction conditions,the extraction yield of TPs reached 9.36%.
