摘要:The some physochemical and chemical properties of the clary sage (Salvia sclareaL.) essential oil were determined. The main constituents in the clary sage essential oil (above 2%) were: linalyl acetate (34.62%),β-linalool (17.67%),α-muurolene (8.27%),β-caryophyllene (5.60%),α-ylangene (5.18%),α-terpineol (4.84%), n-docosane (3.00%), and neryl acetate (2.34%).The thermodynamic and thermal properties of essential oil and its main components were investigated.
