Ultrasound absorption technique was applied to compare the influence of two coumarines: 4-hydroxycoumarin and umbe1liferone (7-hydroxycoumarin) on the phase transition of lipid membranes. There was examined the effect of these coumarines on lipid membranes obtained on the basis of three lecithins differing from each other by the length of acyl chain: dimirystoylphosphatidylcholine (DMPC), dipalmitoylphosphatidylcholine (DPPC) and distearoylphosphatidylcholine (DSPC). 4-hydroxycoumarin was found to change both phase transition temperature of this transition, and cooperativity more than umbelliferone in the case of all the three lecithins.
