Chemical composition of the essential oils from stems, leaves and flowers of salvia leriifolia benth. from Iran

The essential oils obtained by hydrodistillation of the stem, leaf and flower Salvia leriifolia Benth. were analyzed by GC and GC-MS. Thirty-four compounds representing 92.4 % of the stern oil of Salvia leriifolia were identified among them P-pinene (19.0%), germacrene D (11.0%) and delta-cadinene (10.5 %) were the major ones. The leaf oil of the plant was characterized by higher amount of P-pinene (31.5%), 1,8-cineole (24.7%) and cc-pinene (17.5%) among the thirty components comprising 98.9% of the total oil detected. Twenty-seven compounds representing 95.9% of the flower oil of the plant were identified among them gamma-terpinene (62.2 %) and p-cymene (11.1 %) were the major ones. The stem oil of the plant consisted mainly both monoterpenes and sesquiterpenes, while in leaf and flower oils monoterpenes predominated over sesquiterpenes.
