The behaviour of 67 coumarins occurring in higher plants was examined by high-performance liquid chromatography. Resolutions of neutral coumarins were achieved on a normal-phase silica column (lo-pm particles) in hexaneethyl acetate solvent systems and on a Cis reversed-phase column (5 pm) with aque
