Research Progress on Extraction Methods of Tea Functional Components and Their Effects Against Exercise Fatigue
Functional components of tea are mainly tea polyphenols,theanine,tea alkaloids and tea poly-saccharides,which are food-derived substances against sports fatigue.This paper expounded the extraction methods of tea functional components and the mechanism against exercise fatigue,and reviewed research results of tea functional components extracted by water extraction,organic solvent extraction,microwave extraction,ultrasonic extraction,ion exchange,supercritical fluid extraction.The research progress on tea functional components in mediating body metabolism,clearing free radicals,enhancing antioxidant effects,and enhancing effects of skeletal muscles against exercise fatigue were summarized.It provided a basis for the development of foodborne derivatives based on tea as raw materials to resist exercise-induced fatigue.
