Comparison of Salvia Mirzayanii Volatile Compounds Extracted by Headspace Extraction and Hydrodistillation Methods

GC-MS analysis identified forty seven and fourteen components in oils extracted using HD and in the volatile fractions extracted using HSE, respectively. eudesm-7(11) en-4-ol (28.46%), α-terpinyl acetate (12%), germacrene D-4-ol(7.3%), 1,8-cineole (6.22%), δ-cadinene (6.49%), bicyclogermacrene (5.20%) and α-cadinol (5.06%) were recorded as the main components of the essential oil and The major components of the volatile emitted by headspace were linalyl acetate (52.29%), 1,8-cineole (19.77%), α-terpinyl acetate (7.56%) and transβ-ocimene (4.50 %). Exploiting hydro-distillation, sesquiterpenes were identified more than monoterpenes however by using HSE just monoterpenes were recorded by GC/MS analysis. This study proved that HD and HSE methods could be complimentary extraction techniques in order to obtain the complete characterization of plant volatiles.
