Safflower seed oil is known to be one of the richest natural sources of linoleic acid (LA), with values of up to 69.5% of the total fatty acids. Linoleic acid is known to has important biological activity and its absence in a normal diet has been described as responsible for the development of a wide variety of diseases. This work reported purified LA from safflower seed oil could lower blood liquids level of rats with hyperlipidemia. It showed that purified LA from safflower seed oil could decrease the serum total cholesterol and triglyceride concentration significantly, as well as increase the serum high density lipoprotein cholesterol. The serum atherosclerosis index (AI) was decreased remarkably. It demonstrated purified LA from safflower seed oil could improve metabolism of serum lipids and it could play active role of preventing atherosclerosis.

The effect of dietary conjugated linoleic acid (CLA) isomers mixture on antibody titres against sheep blood erythrocytes (SRBC) and immunoglobulin (Ig) G concentration in plasma was studied in broiler chickens. In experiment 1, male and female broiler chicks (11 d of age, Cobb strain) were fed a diet supplemented with 10 g CLA or 10 g safflower-seed oil/kg diet for 2 weeks. An SRBC suspension (5:100, v/v) in a phosphate buffer was intravenously injected at 18 d of age and a blood sample was taken from the wing vein at 25 d of age. Chicks fed the CLA-supplemented diet had enhanced first antibody titres in plasma to SRBC as compared with those fed the safflower-seed oil-supplemented diet, irrespective of sex differences. In experiment 2, male broiler chicks (8 d of age, Ross strain) were fed a basal diet or a diet containing 10 g CLA/kg diet for 3 weeks. CLA in the CLA diet partially replaced the soyabean oil in the basal diet. The SRBC suspension was intravenously injected at 15 and 25 d of age and a blood sample was obtained at 21 and 29 d of age. The first antibody titres against SRBC were higher in chicks fed the CLA diet than those in chicks fed the basal diet, but the second titres were not. Plasma IgG concentrations in chicks fed the CLA diet were higher than those in chicks fed the basal diet on both sampling days. The results showed that dietary CLA enhanced antibody production in broiler chickens.

The objective of this study was to determine the effect of different irrigation intervals (every 7 and every 14 days) and fertilizers (farmyard manure, pellet granules and urea) on the composition of safflower seed and its oil stability. Fertilizers have a significant effect on the carbohydrate, fat, ash and protein contents of safflower seed oil. Pellet granules slightly increased the carbohydrate content, while farmyard manure increased the fat and oil contents of safflower seed oil. On the other hand, urea and farmyard manure increased the fibre content compared with pellets, which slightly decreased it. Irrigation every 7 days increased the protein content. Farmyard manure significantly (P < 0.05) increased the mineral content (iron, potassium and calcium). The use of FTIR spectroscopy revealed that the period of storage significantly (P < 0.05) affects oil stability. The peak intensities (absorbencies) recorded for oil stored at zero time changed after storage for 1, 2 and 3 days, indicating a clear effect of storage time on the oil, and the bands 3008, 2923, 2854, 1747, 1654, 1463, 1377, 1238, 1163, 1099 and 723 exhibited a clear decrease in the intensity of the individual group vibrations, indicating a decrease in oil stability.

Diets that ameliorate the adverse effects of uric acid (UA) on renal damage deserve attention. The effects of casein or soya protein combined with palm or safflower-seed oil on various serum parameters and renal histology were investigated on hyperuricaemic rats. Male Wistar rats administered with oxonic acid and UA to induce hyperuricaemia were fed with casein or soya protein plus palm- or safflower-seed oil-supplemented diets. Normal rats and hyperuricaemic rats with or without allopurinol treatment (150 mg/l in drinking water) were fed with casein plus maize oil-supplemented diets. After 8 weeks, allopurinol treatment and soya protein plus safflower-seed oil-supplemented diet significantly decreased serum UA in hyperuricaemic rats (one-way ANOVA; P < 0·05). In addition, soya protein and casein attenuated hyperuricaemia-induced decreases in serum albumin and insulin, respectively (two-way ANOVA; P < 0·05). Safflower-seed oil significantly decreased serum TAG and UA, whereas palm oil significantly increased serum cholesterol, TAG, blood urea N and creatinine. However, soya protein significantly decreased renal NO and nitrotyrosine and palm oil significantly decreased renal nitrotyrosine, TNF-α and interferon-γ and increased renal transforming growth factor-β. Casein with safflower-seed oil significantly attenuated renal tubulointerstitial nephritis, crystals and fibrosis. Comparing casein v. soya protein combined with palm or safflower-seed oil, the results support that casein with safflower-seed oil may be effective in attenuating hyperuricaemia-associated renal damage, while soya protein with safflower-seed oil may be beneficial in lowering serum UA and TAG.
