Fluorescence spectra and chemical composition of cold-pressed sunflower oleic oils with addition of oils from: 1) basil (Ocimum basilicum), 2) rosemary (Rosmarinus officinalis) and 3) oregano (Origanum vulgare) were studied. The aim of the study is to compare chemical composition of cold pressed oil with and without addition of different plant oils. The concentrations of some elements (essential and toxic) in oil were determined by using Inductively coupled plasma mass spectrometry (ICP-MS) after microwave digestion. Infrared spectroscopic experiments (ATR and transmittance) and NMR spectrum were used to study the fatty acid profile of the analysed oils.
