“…A content of lipids established in fresh borage leaves in this study is in line with that determined on a dry mass basis by del Río-Celestino et al [2008]. The composition of the leaf lipids with palmitic, α-linolenic and linoleic + linolelaidic acids as the major components and with approximate content of myristic and lauric acids was similar to those stated by Griffiths et al [1996], Sayanova et al [1999] and del Río-Celestino et al [2008].…”

“…Griffiths et al [1996] and del Río-Celestino et al [2008] reported a substantial content of stearidonic acid but this component was not determined in this experiment. Griffiths et al [1996], Sayanova et al [1999] and del Río-Celestino et al [2008] also found a few percentage content of γ-linolenic acid, however this component was not detected in this study. Alike, erucic acid established in very low quantities in the borage leaf lipids by del Río-Celestino et al [2008] was not detected in the present research.…”

“…Borage with its cucumber-like smell [Król 2010, Pieszak et al 2012] is cultivated in gardens or collected in natural stands, used in salads, soups or some vegetable and meat dishes [Simon et al 1984, del Río-Celestino et al 2008, Biscotti and Pieroni 2015 or for preparing beverages [Zemmouri et al 2014]. Furthermore, its fresh or candied star-shaped blue flowers serve as an edible decoration of cocktails and confectionery [Adreon 1956, Larson et al 1984.…”

“…Furthermore, its fresh or candied star-shaped blue flowers serve as an edible decoration of cocktails and confectionery [Adreon 1956, Larson et al 1984. In northern Spain borage rosette leaves, leaf petioles and stems are consumed in fresh or lightly fried salads [Medrano et al 1992, del Río-Celestino et al 2008. In south-eastern Italy, consumption of boiled borage leaves and flowers with dressing, in omelet, in soups and stews, pickled or preserved in oil is common [Bianco et al, Biscotti and Pieroni 2015].…”

“…Edible parts are also rich in calcium but with low levels magnesium and natrium and medium amount of nitrate [Bianco et al 1998]. The studies conducted under partially controlled greenhouse conditions in southern Spain by del Río-Celestino et al [2008] demonstrated that rosette leaves of several white and blue flowering borage accessions contained 2.7% of oil, while petioles and stems 1.1% and 1.4% of oil on average in relation to dry mass basis, respectively. In the leaves, depending on flower color, the highest levels were recorded for α-linolenic (26.2-32.2%), palmitic (19.8-24.4%), stearidonic (13.8-15.2%), linoleic + linolelaidic (9.8-12.3%) and myristic (5.5-11.8%) fatty acids.…”

Recently the interest in borage as a vegetable and medicinal plant has increased, yet the knowledge about a content of biologically active compounds in borage grown in Poland remains very scanty. In the experiment carried out in the south-eastern part of the country, fresh borage flowers and leaves contained 0.02% and 0.12% of lipids with the highest level of palmitic acid, i.e. 44.5% and 33.4%, respectively. Flower lipids contained stearic, oleic, elaidic, linoleic, linolelaidic, arachidonic, myristic and lauric acid as well. Besides, leaf lipids were rich in α-linolenic acid (17.7%), less in palmitoleic acid with absence of arachidonic acid. Leaves were found to have 0.16% of essential oil, 1.0% of flavonoids, 9.2 mg vitamin C·100 g f.w.-1 , 1.9 mg carotenoids·100 g f.w.-1 , 0.77 mg chlorophyll a·1 g f.w.-1 and 0.22 mg chlorophyll b·1 g f.w. -1 . Flowers contained more essential oil and vitamin C while less carotenoids, chlorophyll a and b and flavonoids. 45 components were found in the flower essential oil and among them 16 were identified with cumene (62.9%) as a major one. The content of other components was below 3%. As for the leaf essential oil, 18 compounds were detected, and 5 were identified with the highest level of cumene (58.5%) and hexenyl (13.3%). Generally, flowers had more polyphenols and their ferric reducing ability was higher than that of leaves. Besides, a content of remaining unreduced DPPH radical was higher in the flowers. Notably, the time necessary for 50% reduction of the initial concentration of DPPH radical was 2.5 times longer in flowers, whereas their antiradical efficiency 3 fold lower compared to leaves.

Seed oils from Acer species are a potential source of the nutraceutical fatty acids, nervonic acid (cis-15-tetracosenoic acid, NA), and γ-linolenic acid (cis-6, 9,12-octadecatrienoic acid, GLA). To further characterize the genus, seed fatty acid content and composition were determined for 20 species of Acer. Fatty acid content ranged from 8.2% for Acer macrophyllum to over 36% for A. mono and A. negundo. The presence of very-long-chain fatty acids (VLCFA), with chain length of 20-carbons or greater, and GLA were characteristic features of the seed oils. In all species, erucic acid (cis-13-docosenoic acid, EA) was the predominant VLCFA with the highest level of NA being only 8.6% in A. olivianum. Regioselective lipase digestion demonstrated that VLCFA are largely absent from the sn-2 position of seed triacylglycerol, whereas GLA is primarily located at this position. Five Acer species contained low levels (<2%) of cis-12-octadecenoic acid and cis-14-eicosenoic acid, uncommon n-6 fatty acids not previously reported from Acer.Keywords Acer Á Seed oil Á sn-2 MAG Á Very-long-chain fatty acids Á n-6 monounsaturated fatty acids Á Gammalinolenic acid Á Nervonic acid

An optimized 2-D liquid chromatography (LC×LC) set-up, based on the different selectivities of a silver ion (Ag) and a non-aqueous reversed phase (NARP), employed in the first (D1) and the second dimension (D2), respectively, in combination with evaporative light-scattering detection (ELSD), has been developed for the analysis of the triacylglycerol (TAG) fraction in a Borago officinalis oil. The 2-D set-up, thanks to the complementary separation selectivity provided by the two columns, allowed to distribute 78 TAGs throughout the 2-D LC retention plane otherwise unachievable by 1-D LC.
