Abstract: The present invention relates to a method for manufacturing a composition comprising catechin-acetaldehyde condensates and antioxidant or anticancer use thereof. More specifically, the present invention relates to a method for manufacturing a condensate composition of the chemical formula 1 which manufactures the condensate composition of the chemical formula 1 by adding catechin and acetaldehyde with a molar ratio of 1:1 to 1:5 into a solvent. According to the present invention, the catechin-acetaldehyde condensates can be manufactured for each molecular weight through a simple process and anticancer and antioxidant effects of the manufactured composition have significantly improved effects than catechin monomer.

Abstract: PURPOSE: A composition containing a catechin-acetaldehyde condensation product and a method for preparing the same are provided to improve antioxidation and anti-cancer effects. CONSTITUTION: A method for preparing a condensation composition of chemical formula 1 comprises a step of adding catechin and acetaldehyde to a solvent in a molar ratio of 1:1-1:5. The method additionally comprises dialysis of a resultant using a dialyzer having 1.0kDa of molecular weight cut-off to remove unreacted products. A composition for anti-cancer and antioxidation contains the condensation composition.
