Seeds of sweet oranges (Citrus sinensis) were analyzed for oil and fatty acid composition. The crude oil was extracted by the use of soxhlet extraction. The results showed that oil content is as high as 71 %. The physico-chemical assessment gave the following results: refractive index (1.457), peroxide value (4.12 meq/kg) and iodine value (34.06 Wijs). The ATR-IR spectrum of oil showed prominent bands at 3008.6, 2921.73, 2852.7, 1742.86, 1709.23, 1460, 1167.66, 1117.39 and 1051.16 cm-1 that identified fatty acid composition. The percentage compositions of various classes of fatty acids present in the oil were polyunsaturated fatty acids (PUFAs, 39.82 %), monounsaturated fatty acids (MUFAs, 57.08 %) and saturated fatty acids (SFAs, 3.09 %). The oil has linoleic acid (18:2, n-6) as the only PUFA and the second highest fatty acid composition (25.63 %). Palmitoleic acid is the highest MUFA (56.30 %) as well as the highest fatty acid composition while capric acid (C10:0) is the lowest fatty acid (0.02 %). These results and in addition to the low compositions of erucic acid, behenic acid and lignoceric acid indicated that the seed oil of sweet orange is possible suitable for both human consumption and industrial purposes.

Acetate Derivative

Isolation of cellulosic material from the waste material, orange (Citrus sinensis) peel has been carried out. The isolated cellulosic material has been converted into its acetate ester. The acetate derivative has been characterized by titrimetric method and IR spectra. The fatty acid composition of the orange peel has also analyzed by GLC. Successful conversion of agro-waste into its acetate derivative and the fatty acid composition suggest an alternative use of this waste material.DOI: http://dx.doi.org/10.3329/dujs.v60i1.10341  Dhaka Univ.

Induced Aggregation

SummaryPlatelet aggregation and its relation to fatty acid composition of platelets, plasma and adipose tissue was determined in 196 randomly selected, free-living, 40-49-year-old men in two regions of Finland (east and southwest) with a nearly twofold difference in the IHD rate.There were no significant east-southwest differences in platelet aggregation induced with ADP, thrombin or epinephrine. ADP-induced platelet secondary aggregation showed significant negative associations with all C20-C22 ω3-fatty acids in platelets (r = -0.26 - -0.40) and with the platelet 20: 5ω3/20: 4ω 6 and ω3/ ω6 ratios, but significant positive correlations with the contents of 18:2 in adipose tissue (r = 0.20) and plasma triglycerides (TG) (r = 0.29). Epinephrine-induced aggregation correlated negatively with 20: 5ω 3 in plasma cholesteryl esters (CE) (r = -0.23) and TG (r = -0.29), and positively with the total percentage of saturated fatty acids in platelets (r = 0.33), but had no significant correlations with any of the ω6-fatty acids. Thrombin-induced aggregation correlated negatively with the ω3/6ω ratio in adipose tissue (r = -0.25) and the 20: 3ω6/20: 4ω 6 ratio in plasma CE (r = -0.27) and free fatty acids (FFA) (r = -0.23), and positively with adipose tissue 18:2 (r = 0.23) and 20:4ω6 (r = 0.22) in plasma phospholipids (PL).The percentages of prostanoid precursors in platelet lipids, i. e. 20: 3ω 6, 20: 4ω 6 and 20 :5ω 3, correlated best with the same fatty acids in plasma CE (r = 0.32 - 0.77) and PL (r = 0.28 - 0.74). Platelet 20: 5ω 3 had highly significant negative correlations with the percentage of 18:2 in adipose tissue and all plasma lipid fractions (r = -0.35 - -0.44).These results suggest that, among a free-living population, relatively small changes in the fatty acid composition of plasma and platelets may be reflected in significant differences in platelet aggregation, and that an increase in linoleate-rich vegetable fat in the diet may not affect platelet function favourably unless it is accompanied by an adequate supply of ω3 fatty acids.
