Total lipids content and fatty acid composition of seed oils from six pomegranate cultivars

Abstract

The fatty acid composition of the seed oils of six pomegranate (Punica granatum L) cultivars was qualitatively and quantitatively determined by gas chromatography. The seeds contained oil in the range 51-152 mg kg-' dry matter. Intervarietal differences in fatty acid composition were demonstrated (fatty acid esters as % (w/w) total fatty acid esters. Sour varieties had the highest while sour-sweet varieties had the lowest oil content. Eleven fatty acids were identified. In all varieties, the predominant fatty acids were linoleic (25-2-38.6%) and oleic acid (24.8-35.5%) followed by palmitic (1 8.2-22.6%), stearic (6.9-10.4%) and linolenic acid (0.6-9.9%). To a lesser extent arachidic (1.1-3.4%) and palmitoleic acid (0.2-2.7%) were also found in all varieties. Lauric. myristic, behenic and lignoceric acids were rarely detected. As far as we know linolenic (18:3), arachidic (20:0), behenic (22:O) or lignoceric (24 : 0) acids have not been previously reported in the seed oils of edible pomegranate varieties. Lignoceric acid has not previously been found in pomegranate seed oil.

Determination of fatty acids and total lipid content in oilseed of 25 pomegranates varieties grown in Iran

“…The observation on sour and sweet varieties is in agreement with results obtained by Melgarejo et al (1995). Our results on lipid content of sour sweet varieties are in contrast with those reported by Melgarejo et al (1995). Our results on lipid content of sweet varieties are in contrast with those reported by El-shaarawy and Nahapetian (1983).…”

“…El-Nemr et al (1990) showed that 83.6% of the fatty acid was saturated and 16.3% unsaturated. Melgarejo et al (1995) reported that (among six cultivars of Spain pomegranate) 30-33.8% of the fatty acids were saturated and 66.2-69.0% of the fatty acids were unsaturated. Melgarejo and Artes (2000) studied seven clones of pomegranate from another part of Spain and found that 4.16-26.65% of fatty acids of seed oils were saturated and 73.4-95.8% of fatty acid was unsaturated.…”

The Genetic, Biochemical, Nutritional and Antimicrobial Characteristics of Pomegranate (Punica granatum L.) Grown in Istria

“…Conjugated linolenic acid, which is a collective term for the positional and geometric isomers of octadecatrienoic acid (C18:3), amounted to 78.4 % of all of the fatty acids determined in the pomegranate seed oil. These results are in agreement with the literature (49)(50)(51). According to Sassano et al (49), considering all of the geometric isomers of the determined octadecatrienoic acid, punicic acid is by far the most abundant fatty acid in pomegranate seed oil, as it can amount to 72 % of all of the determined fatty acids.…”

Selection of pomegranate (Punica granatum L.) in south-eastern Tunisia

“…The main work on accessions are based on the physico-chemical and technological issues relating to leaves, flowers and fruits (Al Kahtani, 1992;Levin, 1994;Melgarejo et al, 1995;Ben Nasr et al, 1996;Mars and Marrakchi, 1999 Code Origin GME1, GME2, GME3 1, 2, 3 Metouia GO1, GO2, GO3 4, 5, 6 Ouedhref GG1, GG2, GG3 7, 8, 9 Gabès ville GC1, GC2, GC3, GC4, GC5 10, 11, 12, 13, 14 Chenini GM1, GM2, GM3, GM4 15, 16, 17, 18 Mareth GK1, GK2, GK3 19, 20, 21 Kettana acceptability of pomegranate to the consumer and processor depends on a combination of several quality attributes that are related to the physico-chemical and mechanical properties. Fruit quality depends largely on sugar and acid content of the juice.…”
