Studies were carried out on the characterization and glyceride compositions of safflower (Carthamus tinctorius) seed oil. It was observed that safflower seed grown under the soil and climatic condition of Bangladesh contains 32 % of golden yellow coloured oil. The physicochemical characteristics of the oil were studied by the conventional methods and the fatty acid composition by GLC. From the results it is revealed that the oil can be used suitably in paint, varnishes and soap manufacturing industries on account of its high linoleic acid content (75 %), iodine value (148) and saponification value (190). The oil was fractionated into mono-, di-, and triglycerides by silicic acid column choromatography. The trglycerides were accounted for over 90 % of total weight of the oil. Fraction of lipids into three major lipid groups, neutral lipids, glycolipids and phospholipids was carried out by silicic acids column chromatography. The neutral lipids were averaged to 94 % of the total weight of the lipid applied. The percentage composition of individual fatty acids were found to be linoleic acid (75.0), oleic (12.6), palmitic acid (8.4), stearic acid (2.6) and myristic acid (1.4). Bangladesh J. Sci. Ind.

Studies were carried out on the preparation of oleo-resinous wood varnishes by utilizing safflower (Carthamus tinctorius) seed oil. It was observed that safflower seed grown under the soil-texture and climatic condition of Bangladesh, contains about 32 % golden yellow coloured drying oil. The physico-chemical characteristics of the oil were determined by the conventional methods and the fatty acid compositions by GLC. From the results it is evident that the oil can be used suitably in paint and varnishes on account of its high linoleic acid content (75 %) and higher iodine value (148). The oleoresinous wood varnishes was prepared by utilizing safflower seed oil in an open stainless steel beaker by heating the oil with rosin and glycerol. The cooking temperature was maintained at 300O C for ½ an hour. Zinc oxide and lead oxide were used as mould growth inhibitor and catalyst respectively. The varnish thus prepared was found to be water resistant and can be applied on wood surface as tack free coating. Bangladesh J. Sci. Ind. Res. 41(1-2), 77-82, 2006

Δ12 Desaturase

From a random transposon mutagenesis experiment, using Petunia line W138, a seed-specific linoleic acid mutant was isolated. The tagged gene was cloned and identified as a microsomal Δ12 desaturase. Expression of the gene, however, was constitutive and not, as might have been expected, seed-specific. Moreover, self-fertilized homozygous mutants still contain 40% 18:2 in the seed lipid fraction. This suggests that at least two (seedspecific) Δ12 desaturase genes are responsible for the high linoleic acid content in Petunia seed oil. Five members of the microsomal Δ12 desaturase gene family have been identified and isolated. Data are presented on the molecular characterization and tissue-specific expression of these genes, which suggest that, in Petunia the flux through the prokaryotic and eukaryotic pathways of lipid synthesis might be different from the situation found in Arabidopsis.

The fatty acid composition of meat has important effects on its succulence and flavour. The neutral lipids of muscle, are mainly energy stores resembling adipose tissue and affect the succulence of meat. However, the phospholipids, which are structural components of muscle, are important in the development of the species specific cooked meat flavour and odour. We have investigated the effects of feeding diets differing mainly in their linoleic acid content on the fatty acid composition of the lipids of M. Longissimus dorsi (LD) of pigs.

Phenol Content

The phenol content of vegetable oil and its antioxidant activity are of primary interest for human health. Oilseed species are considered important sources of these compounds with medicinal effects on a large scale. Total phenol content (TPC) and antioxidant activity (AA) of safflower oil were previously studied. Nevertheless, there is no report on genotypic differences and antiaging activity of safflower oil. The aim of this study was to determine the TPC, diphenyl-picrylhydrazyl (DPPH), and antiaging activity on three respective accessions from Syria, France, and Algeria of seed oil of safflower grown under semi-arid conditions during 3 consecutive years (2015, 2016, and 2017). The results showed that phenol content as well as antioxidant and antiaging activity varied according to both genotype and years. In 2017, the mean value of TPC in oil seed was two times higher than in 2015 and 2016. Moreover, accessions presented different TPC values depending on the year. The highest antioxidant activity was observed among accessions in 2017 compared to 2015 and 2016. As expected, a positive correlation was found between TPC and antioxidant activity. The inhibition in the collagenase assay was between 47% and 72.1% compared to the positive control (83.1%), while inhibition in the elastase assay of TPC ranged from 32.2% to 70.3%, with the positive control being 75.8%. These results highlight the interest of safflower oil as a source of phenols with valuable antioxidant and antiaging activity, and uses for cosmetics.

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.

SUMMARYA collection of 168 accessions belonging to 62 species and subspecies was evaluated in Cordoba, Spain, in 1985 for fatty acid composition of the seed oil. Linoleic acid content of seed produced in Cordoba (mean temperature during seed formation 27·9 °C) was compared with that of seed obtained under much cooler environmental conditions in Montpellier, France, (mean temperature 19·5 °C). Linoleic acid content ranged from 27·3 to 83·7% in the warm environment and from 45·9 to 88·7% in the cool environment with average values of 64·3% and 75·0%, respectively. Twenty-three species with linoleic acid values of > 70% in both environments were evaluated again, in 1989 in Cordoba (mean temperature 31 °C). Twelve wild species showed consistently high and more stable linoleic acid contents than the cultivated control and could be readily used in breeding programmes to improve oil quality.

Ricinodendron heudelotii, Vitex doniana and Cleome gynandra are three indigenous species whose seeds contain oil that can provide interesting alternatives to conventional seed oil species. This review focused on the physicochemical characteristics of their seeds and the nutritional properties of the extracted oils. Scientific articles and reports were collected and needed information was extracted and synthesized. Ricinodendron seed oil is higher (51.83 mg/100 g) than that of Vitex (28.55 mg/100 g) and Cleome (27.35 mg/100 g). The three seed oils are polyunsaturated oils. Ricinodendron seed oil is composed mainly of linoleic acid (28.3-51.1%). Cleome seeds oil is mainly composed of linoleic acid (56.3% -61.1%) and oleic acid (19.6-23.9%). Ricinodendron seed oil can be used for the preparation of fast drying binder and resins. Vitex seed oil can be used for the production of resin, paint and skin cream production. No application of Cleome seed oil has been stated.
