Chemical variability of Juniperus oxycedrus ssp. oxycedrus berry and leaf oils ...

Boti, Jean Brice; Bighelli, Ange; Cavaleiro, Carlos; Salgueiro, Ligia; Casanova, Joseph

The composition of 27 samples of berry oil and 54 samples of leaf oil of Juniperus oxycedrus ssp. oxycedrus from Corsica was investigated by GC, GC-MS and 13C-NMR. The main constituents were terpene hydrocarbons, especially alpha-pinene, myrcene and germacrene D in the oils from berries and alpha-pinene, beta-phellandrene and Delta3-carene in the oils from leaves. The results of the analyses were submitted to k...

The essential oils isolated from twigs of Juniperus cedrus Webb & Berth. grown on Madeira were analysed by GC, GC-MS and 13C-NMR. The oils consisted mainly of monoterpene hydrocarbons (53.1-87.8%), the main ones being alpha-pinene (19.6-55.3%), limonene (17.3-32.7%) and Delta-3-carene (5.5-15.7%). The sesquiterpenoid fraction (4.1-22.3%) was dominated by E-caryophyllene (1.6-7.4%), while sandaracopimaradiene (0...

The essential oil composition of 68 individual plants of Juniperus phoenicea from Portugal was investigated by GC, GC-MS and 13C NMR. [alpha]-Pinene, [beta]-phellandrene, [alpha]-terpinyl acetate and myrcene were found to be the main constituents. Botanical and chemical data as well as phytogeographical distribution indicate J. phoenicea var. turbinata as the unique subspecies occurring in Portugal. Nevertheles...

The composition of 50 samples of essential oil of individual plants of Juniperus phoenicea subsp. turbinata from Corsica was investigated by GC, GC-MS and 13C NMR. [alpha]-Pinene, [beta]-phellandrene, [alpha]-terpinyl acetate, [Delta]-3-carene, myrcene and [alpha]-phellandrene were found to be the main constituents. The results were submitted to cluster analysis and discriminant analysis which allowed two group...
