摘要
Abstract
The change of theabrowmins in pu'er tea before and after solid fermentation was studied. The results showed that the theabrowmins content is about 13% after 8-day fermentation and the highest yield of 24% can be obtained through optimizing the fermentation conditions, which is 8.23 times raised compared with unfermented pu'er tea. The theabrowmins were prepared by organic solvent extraction from fermented pu er tea. With the yield of theabrowmins as index, the extraction conditions were optimized. The yield is about 10% of the sample and the theabrowmins content is 826. 4 mg/g in the sample. Antioxidant activity of the sample indicated that the sample has strong antioxidant activity.关键词
