“…Polar lipids are known to be an important constituent of membrane lipids (15). These results agreed with the previous observations on mango {12}, papaya (20) and Concord grape (V iris labrusca var. Erucic acid of rapeseed {16-18} and petroselinic acid of parsley seed (19) were localized on nonpolar lipid fractions.…”

Fatty acids of commonly available fruit pulps have been analyzed by capillary gas chromatography of their methyl esters and by gas chromatography-mass spectrometry as their dimethyl disulfide adducts. The gas chromatographic and mass spectrometric data proved that these fruits always contained cis-vaccenic (cis-ll-octadecenoic) acid as a component fatty acid of their pulp lipids. The concentration of cis-vaccenic acid in total octadecenoic acids ranged from 1.9% to 95.1% in the fruit pulps examined. The highest concentration of this acid was detected in pulp lipids of Japanese persimmon (Diospyros kaki). In fruit pulp lipids, cis-vaccenic acid was a common octadecenoic acid as well as oleic acid.Many studies have shown that cis-vaccenic (1) (cis-11-octadecenoic) acid is a component fatty acid of microorganisms, animal tissues and human tissues. The metabolism, distribution and origin of cis-vaccenic acid in these materials have been well investigated (2-6). On the contrary, less attention has been given to cis-vaccenic acid in higher plant lipids because of its low concentration (i.e., 0.5-2%) in common vegetable seed oils. The biosynthetic pathway of cis-vaccenic acid has not yet been confirmed in higher plants (7,8). We revealed the content of cis-vaccenic acid (as pyrrolidide) in triacylglycerols of seven kinds of common vegetable seed oils by gas chromatography-mass spectrometry (GC-MS) (9). Recently, we devised a convenient procedure for preparation of dimethyl disulfide adducts of fatty acid positional isomers (10), and developed a rapid and simple method for determination of cis-vaccenic acid content by GC-MS of the adducts (11). By use of a combination of these GC-MS systems, a convenient capillary GC, and other chromatographic, spectrometric and chemical methods, cis-vaccenic acid has been proved to be one of the major fatty acids (35-50% of total octadecenoic acids) in pulp lipids of mango (Mangifera indica) (12).In this paper, we report the presence of cis-vaccenic acid in fruit pulp lipids and describe analytical methods suitable for determination of monoenoic fatty acid positional isomers. No paper has hitherto been published on cis-vaccenic acid in fruit pulp lipids except for our previous paper on mango pulp lipids (12).

“…OECD (2010) indicated that FA levels are low in papaya and palmitic acid and linolenic acid are the two major FAs in papaya. Chan and Taniguchi (1985) reported that FA composition changes in papaya pulp during fruit ripening stage, however, no significant difference was found in lipid composition with maturity of papaya fruits.…”

Some physicochemical characteristics like nutritional values, sugar content, and fatty acid composition (FAs) in fruits of four papaya (Carica papaya L.) cultivars ('Red Lady', 'Sunrise Solo', 'Tainung', and 'BH-65') grown under plastic greenhouse conditions in the Mediterranean region of Turkey were evaluated. The chemical characteristics, except acidity in the fruits, significantly varied among the cultivars. Nitrogen (N) was the most abundant mineral in all papaya cultivars and ranged from 0.80 g･100 g -1 in 'Red Lady' to 1.28 g･100 g -1 in 'BH-65' in fresh weight. Potassium (K) and calcium (Ca) were found the highest amount in dry weight. Glucose and fructose were identified as the main sugars in all cultivars. Sucrose was in trace amounts in the three cultivars, but not detectable in cultivar 'Red Lady'. Twenty-five FAs were detected in the papaya fruits. Polyunsaturated fatty acids (PUFAs) were found to be in a highest amounts compared to the saturated fatty acid (SFAs) and monounsaturated fatty acids (MUFAs). Palmitic (C16:0), oleic (C18:1), and linoleic (C18:2n6) acids were the major fatty acids detected in all cultivars. The results of this study implied that dietary intake of papayas may supply substantial nutrient components necessary for human health.
