The essential oil of Bupleurum fruticosum L. from Corsica: a comprehensive study.

A detailed analysis of Bupleurum fruticosum oil was carried out by combination of GC (RI), GC/MS, and 13C-NMR analyses. After fractionation by column chromatography, 34 components accounting for 97.8% of the oils were identified.

Volatile components of peel and leaf oils of lemon and lime species.

Peel and leaf oils of 43 taxa of lemons and limes were obtained from fruits and leaves collected from trees submitted to the same pedoclimatic and cultural conditions. Their chemical composition was investigated by capillary GC, GC-MS, and (13)C NMR, and the results were submitted to principal component analysis to check for chemical variability. Three major chemotypes were distinguished for lemon peel oils: limonene; limonene/beta-pinene/gamma-terpinene; and limonene/linalyl acetate/linalool.
