Chemical constituents of essential oil of Senecio bombayensis flower
Abstract
The essential oil composition of the flower of Senecio bombayensis was analysed by gas chromatography and gas chromatography/mass spectrometry . Forty -six compounds representing 98.2% of the total oil were identified. The m ain constituents are linalool (26.3%), β-cedrene (14.5%), E-β-farnesene (10.8%), 2,5-dimethoxy-p-cymene (7.0%), E-β-ocimene (5.9%), terpinen-4-ol (5.1%) and Z-β-ocimene (4.7%). The oil is rich in sesquiterpene hydrocarbons (38.1%), followed by oxygenated monoterpenes (32.3%), monoterpene hydrocarbons (17.7%), oxygenated sesquiterpenes (6.0%) and others (4.1%).
