Abstract
Scutellariais a member of Labiatae, distributed in mediteranean region and south of Asia. In Iran 20 species are present in center, northern, northwest and western districts. The aerial parts of Scutellaria pinnatifida. were collected from Touchal in Tehran province at full flowering stage in May 2004. Essential oil was isolated by hydrodistillation from the aerial parts of plant and analysed by a combination of capillary GC and GC/MS. The yeild of essential oil was obtained in 0.07% (w/w). 29 compounds in the oil have been identified representing 96.6% of the oil. The main constituent was germacrene D (39%). Other main components were β-caryophyllene, farnesene and bicyclogermacrene.
