The present invention provides a novel method for assaying OPC contained in natural substances, foods and beverages, pharmaceuticals and/or cosmetics. The present invention is a novel method for assay of OPC which assays anthocyanidin, obtained by hydrolysis of OPC, to determine the total amount of OPC, and elucidates the proportions of the polymerization degrees of OPC by high performance liquid chromatography (HPLC) to determine the contents of the respective polymers in OPC.

La présente invention concerne un procédé inédit de dosage de l~OPC contenue dans des substances naturelles, des aliments et des boissons, des produits pharmaceutiques et/ou des cosmétiques. La présente invention est un procédé inédit de dosage de l~OPC qui effectue le dosage de l~anthocyanidine, obtenue par hydrolyse de l~OPC, dans le but de déterminer la quantité totale d~OPC, et qui détermine les proportions des degrés de polymérisation de l~OPC par chromatographie en phase liquide à haute performance (HPLC) dans le but de déterminer la teneur des polymères respectifs dans l~OPC.
