Title:
ANALYSIS METHOD
Document Type and Number:
WIPO Patent Application WO/2019/138817
Kind Code:
A1
Abstract:
An analysis method including: a sample preparation step of preparing a measurement sample by mixing a material of interest that contains pyrroloquinoline quinone or a salt thereof with glycine in such a manner that the pyrroloquinoline quinone or the salt thereof can react with the glycine to produce imidazopyrroloquinoline or a salt thereof; and a quantification analysis step of quantifying the quantities of the pyrroloquinoline quinone and the salt thereof contained in the material of interest on the basis of chromatograms of the imidazopyrroloquinoline and the salt thereof contained in the measurement sample which are determined by a chromatography method.
