Abstract:
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.
