Neutral lipids, glycolipids, phospholipids, pigments, and essential oil of the above-ground part of Origanum onites L. (Lamiaceae) are isolated and characterized for the first time. The fatty-acid composition of the lipids and the components of the hydrocarbons, sterols, and essential oil are determined by GC/MS. Linolenic and palmitic acids dominate in the acids of the lipids. The main components of the hydrocarbons are nonacosane; of the sterols, beta -sitosterol; of the pigments, chlorophylls a and b. A total of 54 components are identified in the essential oil.
