Abstract
The Essential Leaf Oils Of Origanum Syriacum Var. Aegyptiacum and Stachys Aegyptiaca (Lamiaceae), Were Prepared By Hydrodistillation and Studied By Cgc and Gc-Ms. Among The 28 Compounds Identified In The Oil Of Origanum, Up To 83% Consists Of The Antiseptic and Flavoring Agent Carvacrol. In Addition, Carvacrol Methyl Ether and Carvacryl Acetate Are Present In Minute Amounts. The Monoterpene Hydrocarbon Fraction Accounts For Nearly 12% Of The Oil Of Which P-Cymene, γ-Terpinene, Myrceneand A-Thujene Are The Major Components. The Sesquiterpene Compounds and The Monoterpene Alcohols Occur In Rather Insignificant Concentrations.
The Oil Of Stachys Aegyptiaca Consists Mainly Of 14 Monoterpene Hydrocarbons (75%), 4 Oxygenated Monoterpenes (1.1%) and 7 Sesquiterpene Hydrocarbons (17%). The Dominant Compound Is Ot-Pinene.
