BIOLOGICAL MEMBRANE PHOSPHOINOSITIDE SEPARATION METHOD

摘要

Provided is a method for separating PIPs by which isomers of PIPs can be separated without deacylating the PIPs. The method includes at least a separation step of injecting a sample containing a plurality of PIPs into an analysis flow path of a supercritical fluid chromatograph having a separation column filled with a separation medium containing β-cyclodextrin and separating the plurality of PIPs by supercritical fluid chromatography.
