AUTHOR(S): Emmanuel E Essien, R Ascrizzi and Guido Flamini
ABSTRACT:The leaf and floral essential oils of Tithonia diversifolia (Hemsley) A. Gray (Asteraceae) were analyzed for composition by means of gas chromatography-mass spectrometry (GC-MS). Forty-two constituents were identified in the leaf and floral oils, accounting for 97.2% and 95.3% of the total composition, respectively. Germacrene D (46.0%), β-caryophyllene (12.2%), and methyl carvacrol (9.8%) were the prominent components of the leaf oil, while the main constituents of the floral oil consisted of germacrene D (32.5%), α-pinene (7.5%), and β-caryophyllene (6.6%).
