The behaviour of equimolar mixtures of (x-tocopherol with monogalactosyldiacylglycerol (MGDG) and digalactosyldiacylglycerol (DGDG) and phospholipids (PL) isolated from wheat calli cultured on media with and without cadmium was investigated at the air-water interface by surface pressure-area (pi-A) measurements established using an automated Langmuir-type film balance. It was found that monolayers of all studied compounds were expanded. The additivity rule was not fulfilled and the collapse pressure of mixtures was different from these recorded for pure components. This can be related with the existence of interactions between molecules in mixed monolayers. Tocopherol diminished the differences between parameters of monolayers formed by lipids extracted from objects cultivated on various media (with and without cadmium). (C) 2009 Elsevier Ireland Ltd.
