The aim of the diploma thesis was the identification of fatty acids contained in vegetable oils by gas chromatography. Amount of fatty acids was monitored in dependence on the duration and conditions of storage. Conditions for storage were selected at room temperature and refrigerator temperature. In total fourteen oils were analyzed - avocado oil, pumpkin seed oil, grape seed oil, jojoba oil, corn oil, linseed oil, macadamia oil, almond oil, apricot-stone oil, olive oil, castor oil, rice oil, sunflower oil and soya bean oil. Gas chromatography was applied for identification and quantification of fatty acids. Methanol esterification method using potassium hydroxide catalysis was chosen for preparing of the samples of the fatty acid methylesters. Eight fatty acids were observed in the vegetable oils : myristic, palmitic, palmitoleic, stearic, oleic, linoleic, gama-linolenic and linolenic acids.
