Essential oil composition ofVerbesina diversifolia DC
Flavour and Fragrance Journal, 2006The essential oils from leaves of Verbesina diversifolia DC., at different ontogenetic stages, were obtained by hydrodistilation and analysed by GC–FID and GC–MS. The oils were mainly (56.7–75.7%) constituted by sesquiterpenes; 82.6–94.1% of the chemical composition of the essential oils of plants at the flowering stage were identified, with β ...

Essential oil composition of Chamelaucium uncinatum
Phytochemistry, 1995The composition of the essential oils of different genotypes of Chamelaucium uncinatum has been examined. The major compounds were identified as α-pinene, citronellal, limonene, linalool and α-terpinyl acetate. Three chemotypes of C. uncinatum were identified based on the relative proportions of α-pinene, citronellal and limonene present.
