 [Biochemical evaluation of borage (Borago officinalis) rosette leaves through their essential oil and fatty acid composition., Mhamdi, B., Aidi, W.W., Marzouk, B., The Italian journal of biochemistry, 56(2), 2007, 176-179]
-"The essential oils obtained from the fresh leaves and flowers of Borago officinalis collected in the region of Amdoun (northwestern Tunisia) were examined by GC and GC/MS. Twenty-three volatile compounds were identified. The oil yields expressed on a dry weight basis were 0.14% and 0.24% for the leaves and flowers, respectively. The main compound determined in flower and leaf oil was (E,E)-2,4-decadienal with 43.4% and 26.9% in the leaf and flower oils, respectively. The oils from the two organs showed the predominance of the aldehyde class which constituted 61.2% and 61.9% in the leaf and flower oils, respectively. Other classes present in important percentages in the two organs were alcohols (22.4%) in the leaf oil and phenols (13.2%) and monoterpene hydrocarbons (12.2%) in the flower oil." \\

 "Gas chromatography–mass spectrometry analysis of seed Borago officinalis essential oil (EO) revealed the presence of 16 volatile components. β-Caryophyllene (26%) and p-cymene-8-ol (19.7%) represented the major components, while nonadecane (0.7%) and hexanol (0.7%) were the minor ones. The EO composition was characterized by higher abundance of oxygenated monoterpenes (27.7%), followed by sesquiterpenes (26%). Fatty acid composition showed the predominance of linoleic (35.4%), oleic (24.2%) and γ-linolenic (20.4%) acids." \\
