An analysis method having: a sample preparation step of preparing a measurement sample by mixing a measurement object containing pyrroloquinoline quinone or a salt thereof with glycine so that the pyrroloquinoline quinone or the salt thereof reacts with the glycine to produce imidazopyrroloquinoline or a salt thereof; and a quantitative analysis step of determining quantitatively the amount of the pyrroloquinoline quinone and the salt thereof contained in the measurement object, based on a chromatogram of the imidazopyrroloquinoline or the salt thereof contained in the measurement sample obtained by chromatography.

Analysis method

Disclosed are a phenoxyalkylamine represented by the following general formula I and a salt of said phenoxyalkylamine represented by the following general formula II: ##STR1## wherein R represents a linear saturated hydrocarbon having 7 to 12 carbon atoms, n is an integer of from 1 to 5, m is an integer of from 2 to 4, and HX represents a mineral acid. These compounds have strong bacteriostatic and bactericidal actions for plants with no phytotoxicity. Therefore, these compounds are effectively used as the active ingredient of an agricultural and horticultural bactericide.
