Lipids and essential oil of Origanum onites

Neutral lipids, glycolipids, phospholipids, pigments, and essential oil of the above-ground part of Origanum onites L. (Lamiaceae) are isolated and ch aracterized for the first time. The fatty-acid composition of the lipids an d the components of the hydrocarbons, sterols, and essential oil are determ ined by GC/MS. Linolenic and palmitic acids dominate in the acids of the li pids. The main components of the hydrocarbons are nonacosane; of the sterol s, beta -sitosterol; of the pigments, chlorophylls a and b.
