EPIGALLOCATECHIN DIMER AND TRIMER HAVING LIPASE INHIBITORY ACTIVITY AND/OR ANTIOXIDATIVE ACTIVITY

摘要

Lipase activity inhibitors that exhibit high inhibitory activity against pancreatic lipases and / or contribute to regulating fat absorption from food and / or contributing to the control or prevention of obesity, foods and beverages containing the same, and are highly desirable and not adversely affect taste It is intended to provide a tea-derived lipase inhibitor. Also provided are methods of making lipase inhibitors. It is also intended to provide antioxidants. To overcome this challenge, epigallocatechin dimers (oolong homo bis flavans) or trimers are added to foods or beverages. Thus it is possible to regulate the absorption of fat from food and to obtain an antioxidant effect. The compound may be prepared by reacting epigallocatechin gallate with formaldehyde in the presence of an acid.
