Aim. To investigate the complex formation of 7,3',4'-tryoxyflavonol of flavonoids group with cellular phosphatidylcholine. Methods. Semi-empirical quantum chemistry, spectroscopy NMR. Results. The changes in conformational status of 7,3',4'-tryoxyflavonol at complex formation have been shown. Conclusions. The conformational changes in phosphatidylcholine take place under the 7,3',4'-tryoxyflavonol/phosphatidylcholine complex formation.
