Chemical Constituents of Essential Oils From the Leaves, Stems and Aerial Parts of Salvia virgata Jacq. From Iran

Abstract

Chemical composition of the essential oils obtained by hydrodistillation of the dried leaves, stems and aerial parts of Salvia virgata Jacq. was analyzed by a combination of GC and GC/MS. Twenty-four components were identified in the leaf oil with β-caryophyllene (35.2%), (Z)-β-farnesene (10.1%), caryophyllene oxide (6.1%) and α-pinene (5.7%) as the main constituents. Twenty-three compounds were characterized for the stem oil with hexadecanoic acid (56%) and β-caryophyllene (7.6%) as the major components. Twenty-five compounds were identified in the aerial parts oil with β-caryophyllene (23.1%), sabinene (18.2%) and (Z)-β-farnesene (12.3%) as the main constituents. Two oils (leaf and flowering aerial parts) consisted mainly of sesquiterpene hydrocarbons, while in the stem oil fatty acids predominated over monoterpenes and sesquiterpenes.
