| "Traditionally borage was cultivated for culinary and medicinal uses, although today commercial cultivation is mainly as an oilseed. The seed oil is desired as source of gamma-linolenic acid (GLA), for which borage is the highest known plant-based source (17-28%)... Borage is used as either a fresh vegetable or a dried herb. As a fresh vegetable, borage, with a cucumber-like taste, is often used in salads or as a garnish... The flower...has a sweet honey-like taste and is one of the few truly blue-colored edible substances... Although often used in soups, one of the better known German borage recipes is the Green Sauce (Grüne Soße) made in Frankfurt." \\ | "Traditionally borage was cultivated for culinary and medicinal uses, although today commercial cultivation is mainly as an oilseed.

| "Borago officinalis rosette leaves were sampled in the region of Amdoun (Tunisia) during different stages of their development. Essential oil contents varied from 0.01% to 0.13% respectively in young and adult leaves. Twenty three volatile compounds were identified. Hydrocarbons, mainly represented by nonadecane (29.8%), tetracosane (11.3%) and heptacosane (4.7%), constituted the major class in the young leaves (45.8%), followed by aldehydes (22.4%). The percentages of these two classes decreased to reach respectively 15% and 8.1% in adult leaves in favour of alcohols (57.9%) where cis-3-hexenol (29.6%) and hexanol (14.5%) were the main compounds." \\ | "Borago officinalis rosette leaves were sampled in the region of Amdoun (Tunisia) during different stages of their development.

| "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 [[http://www.thegoodscentscompany.com/data/rw1028121.html|(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." \\ | "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.

| "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." \\ | "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.
