Interest in oilseed crops for agro-industrial research and development projects has increased in the Mediterranean area, in recent years. Safflower (Carthamus tinctorius L.) is of potential interest for agriculture mainly due to fatty acid content variability in the seed oil. The aim of this study was to assess the agronomic performance of 16 new safflower accessions together with safflower variety Montola 2000, used as a reference, in a semi-arid environment. Research was carried out in Sicily (Italy) from 2013–2014. Hierarchical cluster analysis carried out on the fatty acid composition of safflower accessions resulted in their division into four main groups. Linoleic, oleic and palmitic acids were the main fatty acids present in the accessions. Seed yield was 1.11 t ha−1 on average and seed oil content was found to be approximately 35.01% of dry matter on average. Positive and significant relationships between seed/oil yield and other tested traits were found. The carbon, hydrogen and nitrogen content as a percentage of dry matter varied greatly both for the above- and belowground plant parts on average. This study confirms the interest of safflower for both food and non-food applications, offering interesting prospects in semi-arid regions.

The objective of this study was to show and crosscheck the seed yield and oil composition of three different seeds growing in different regions of Turkey. Extraction with n-hexane solvent indicated that there were differences in terms of oil yield between the regions. The average oil yield was 33.8% and 33.0% seed-I, 35.7% seed-II (Region-a) and 32.6% seed-III (Region-b) oil yields were obtained. The highest fatty acid content of hemp was found as: linoleic acid (average 55.24%) followed by oleic acid (average 17.20%) and α-linolenic acid (average 16.02%). Crude ash, total dry matter and crude protein analyzes were also performed. It was observed that the hemp seed oil yield was dependent on the extraction whereas extraction had no influence on the fatty acid content. Comparison of the seed oil yield with the other studies indicated that geographical region as well as the extraction method may affect the seed oil yield.

Summary A comparative study of the oil yield and fatty acid composition of three Salvia species seeds collected in different locations has been conducted. Seed oil extraction was made using a Soxhlet-extractor and fatty acid analysis was undertaken using a GC-FID. The effect of the collecting site on oil yield, as well as the content of individual fatty acid and total fatty acid and fatty acid content was significant. Seed oil yield varied from 14.94 to 22.83% and the total fatty acids ranged from 67.36 to 82.49 mg/g DW. α-Linolenic (24.02-49.19%), linoleic (20.13-42.88%), oleic (12.97-17.81%) and palmitic (8.37-16.63%) acids were the most abundant fatty acids in all analyzed samples. α-Linolenic acid was found to be the major fatty acid in S. verbenaca and S. officinalis species, however, S. aegyptiaca was characterized by the prevalence of linoleic acid. Among the unsaturated fatty acids, which were represented in all samples in high amounts (78.16-89.34%), the polyunsaturated fatty acids (α-linolenic and linoleic acids) showed important levels ranging from 63.09 to 74.71%. Seeds of S. verbenaca were the richest in polyunsaturated fatty acids.

Hura Crepitans

Oil was extracted from the seed of Hura crepitans using hexane in a soxhlet extractor and analyzed for iodine value, saponification value and free fatty acid content. The dominant fatty acid in the oil was C18:2 (52.8±0.10%) while the iodine value was 120.10±0.70 g iodine/100 g. Biodiesel was produced from the oil using a two-step reaction system involving a first step of pretreatment via esterification reaction and a second step via transesterification reaction. The pretreatment step showed that free fatty acid in Hura crepitans seed oil can be reduced in a one-step pretreatment of esterification using H2SO4 as catalyst. The biodiesel produced from Hura crepitans seed oil had an acid value of 0.21±0.00 mg KOH/g, flash point of 152 ± 1.10°C, copper strip corrosion value of 1A, calorific value of 39.10±0.30 mJ/kg, cetane number of 45.62±0.30, and density of 0.86±0.02 g cm−3. The process gave a biodiesel yield of 98.70±0.40% with properties within the recommended values of EN 14214.

This paper investigated the effects of Prunus pedunculatus (P. pedunculatus) seed pre-treatment, including microwaving (M), roasting (R), steaming (S) and roasting plus steaming (RS) on crude oil quality in terms of yield, color change, fatty acid composition, and oxidative stability. The results showed an increase in monounsaturated fatty acid content and oxidative stability of the oils obtained from different processing treatments compared to the oil obtained from raw seeds (RW) without processing. The oils, obtained from pretreated seeds, had higher conjugated diene (CD) and 2-thiobarbituric acid (2-TBA) values, compared to that obtained from RW when stored in a Schaal oven at 65 °C for 168 h. However, polyphenol and tocopherol contents decreased in all oil samples, processed or unprocessed. The effect of pre-treating the seeds was more prominent in the oil sample obtained through the RS technique, and showed higher oxidative stability than the other processed oils and the oil from RW.

The synthesis of triacylglycerols was investigated in microsomes (microsomal fractions) prepared from the developing cotyledons of sunflower (Helianthus annuus). Particular emphasis was placed on the mechanisms involved in controlling the C18- unsaturated-fatty-acid content of the oils. We have demonstrated that the microsomes were capable of: the transfer of oleate from acyl-CoA to position 2 of sn-phosphatidylcholine for its subsequent desaturation and the return of the polyunsaturated products to the acyl-CoA pool by further acyl exchange; the acylation of sn-glycerol 3-phosphate with acyl-CoA to yield phosphatidic acid, which was further utilized in diacyl- and tri-acylglycerol synthesis; and (3) the equilibrium of a diacylglycerol pool with phosphatidylcholine. The acyl exchange between acyl-CoA and position 2 of sn-phosphatidylcholine coupled to the equilibration of diacylglycerol and phosphatidylcholine brings about the continuous enrichment of the glycerol backbone with C18 polyunsaturated fatty acids for triacylglycerol production. Similar reactions were found to operate in another oilseed plant, safflower (Carthamus tinctorius L.). On the other hand, the microsomes of avocado (Persea americana) mesocarp, which synthesize triacylglycerol via the Kennedy [(1961) Fed. Proc. Fed. Am. Soc. Exp. Biol. 20, 934-940] pathway, were deficient in acyl exchange and the diacylglycerol in equilibrium phosphatidylcholine interconversion. The results provide a working model that helps to explain the relationship between C18- unsaturated-fatty-acid synthesis and triacylglycerol production in oilseeds.
