Abstract
The essential oil of Cistus ladaniferus L., obtained from plants of Spanish origin grown in Corsica, was investigated by 13C-NMR spectroscopy (identification of components) and GC (quantification). First, a bulk sample was analysed and 45 constituents were identified. The main components were α-pinene (39%), viridiflorol (11.8%), ledol (3.3%) and bornyl acetate (3.1%). The occurrence of cyclosativene, γ-cadinene, (E)-β-farnesene and β-eudesmol in the essential oil of Cistus ladaniferus is reported here for the first time. Then, in order to study the chemical variability of individual oils, we examined 20 samples. α-Pinene (11.1–47.4%) was the most abundant component in 18 of the 20 samples, followed by trans-pinocarveol (4.4–10.9%) and viridiflorol (4.7–10.7%). Two samples exhibited a different chemical composition, not as yet described, characterized by the predominance of viridiflorol (20–22.6%), ledol (6.4–6.7%) and trans-pinocarveol (5.4–8.6%). © 1997 John Wiley & Sons, Ltd.
