ABSTRACT
In the text and tables will be used the same symbols and criteria applied in the chapters on the peel cold pressed oils and on petitgrain oils.
Guenther (1949) reported the physicochemical indices of neroli oils of different origins, and, for some of these, the esters content (expressed as linalyl acetate), the free alcohols content (expressed as linalool) and content of methyl anthranilate. These values were the following:
Esters Free alcohols Methyl anthranilate
France 6.7-21.0% – 0.4-1.2% Italy 7.3-14.7% 49.9-67.5% 0.6-1.4% Spain 12.3-32.3%a – – Haiti 8.7-18.7% – –
For the neroli oil produced in France, Guenther (1949) also reported the following approximated composition:
Hydrocarbons (α-pinene, camphene, limonene, heptacosane) 35% (−)-linalool 30% geraniol + nerol 4% (+)-α-terpineol 2% linalyl acetate 7% geranyl acetate + neryl acetate 4% (+)-nerolidol 6% indole < 0.1% methyl anthranilate 0.6% acetic acid + palmitic acid 0.1% Others (decanalt, esters of phenyl acetic acid and of benzoic acid, jasmone*, farnesol*) 11.2%
Guenther also found β-ocimene, phenyl ethyl alcohol, and trace amounts of phenols. The same quantitative data reported by Guenther were later included by Gildmeister and Hoffmann (1959) and by Bigi (1962) in their reviews respectively.
