In this paper, chemical component and antioxidative activities aga-inst lipid tea yellow pigment (TYP) are studied. The results show that theTYP contains vitamin C, vitamin E, tea polyphenols, amino acid, and otherbiologically active substances. TYP is a highly valuable product due toits chemical composition and physiological effect on human body. Anti-oxidativ activity in TYP is higher than in those vitamin E. tea polyp-henols, and butylhydroxy--toluol(BHT) .Technological scheme of TYP man-ufacturing consists of the following processes: water extract obtaining.extract filtration and drying. By using these technological methods, the.econ-omic benefits can be gained significantly.
