By using 2,4,6-trihydroxyacetophenone adsorbed to cation-substituted zeolite, laser desorption/ionization mass spectrometry for six kinds of bioactive substances was carried out. The compounds, which were usually difficult to observe by conventional matrix-assisted laser desorption/ionization mass spectrometry, were ionized by cation adduction from the zeolite surface.
