Table 3: _Cont._According to the data given in Table 3, safflower oil had the greatest mass fraction of linoleic acid C18:2n6c (74.25%). Some reports have shown [42; 43] that the FA composition can depend on the influence of the environmental conditions. The samples did not include oils containing FAs with a low molecular weight, such as carbonic acid C6:0, acrylic acid C8:0, capric acid C10:0 and lauric acid C12:0. The content of palmitic acid C16:0 was 6.90%. The content of stearic acid C18:0 was around 2.50%. In the samples, the content of oleic acid C18:1n9c was 15.50%, that of linolenic acid C18:3n3c was 0.07% and that of arachidonic acid C20:0 was 0.23%. The mass fractions of the following FAs were represented in amounts not exceeding 0.5%: behenic acid C22:0 and lignoceric acid C24:0. Similar results have previously been reported [43]. Moreover, the sowing time also affected oleic and linolenic acids to some degree. A high content of the total amount of USFAs was found in safflower (90.06%), sunflower (85.11%) and linseed oils (89.16%), the results of which corresponded to the research information [44]. [PERSON] et al. [45] reported that FA compositions in cultivated and wild species of safflower oil were not considerably different. [PERSON] et al. [46] reported a higher ratio of SFAs (17.1%) than Giakoumis' [47] and Kazakhstan's safflower oil, at 10.1 and 9.8, respectively, as shown in Table 3 and Figure S5.
