Abstract
The volatile constituents of flowers and aerial parts of Crassocephalum crepidioides (Benth.) S. Moore commonly a weed, collected from Western Ghats region of India, was analyzed by GC and GC-MS. The essential oils of flowers and aerial parts were dominated by monoterpene hydrocarbons (82.0%; 70.8%) with myrcene (45.3%; 46.1%), β-phellandrene (20.2%; 31.0%) as major constituents. The other constituents in flower oil were dauca-5,8-diene (6.9%), trans-β-farnesene (4.8%) and daucene 3.6%), while allo-aromadendrene (4.9%), α-muurolene (2.6%) and β-panasinsene (2.4%) were identified in the aerial parts oil. © 2011 Universal Research Publications.
