Chemical compositions of the essential oils in Salvia sahendica Boiss. & Buhse at two different growth stages

Abstract

Salvia, the largest genus of Lamiaceae, is represented in Iranian flora by 58 species, 17 of which are endemic. Some of these species have been used in folk medicine all around the world for their antibacterial and antitumor activities as well as flavoring agent in perfumery and cosmetics. The aerial parts of Salvia Sahendica were collected at vegetative and flowering stages from the Sahand Mountain near to Sardroud (Azarbayjan province, Iran). The essential oils were isolated by hydrodistillation Clevenger type apparatus and analyzed by GC and GC-MS. In vegetative stage, Thirty-two components were identified, representing 98.5 % of the total oil. α- pinene (28.5%), β- pinene (26.1%), sabinene (10.3%), germacrene- D (9.6%) and 1,8- cineole (4.9%) were the main components in vegetative stage. In flowering stage, Thirty-five components were identified, representing 99.8% of the total oil. α- pinene (18.9%), β- pinene (18.5%), 1,8- cineole (13.9%), linalyl acetate (8.4%), bicyclogermacrene (8.2%), sabinene (7.6%) and linalool (5.3%) were the main components at flowering stage.
