The content of C16, C18, C20, C22 fatty acids were measured by gas liquid phase chromatography and linoleic and linolenic acids by spectral analyses on the oil from seven varieties of rapeseed grown at seven stations in Western Canada. Significant differences were found between varieties for all oil properties except the content of C16 acids. The major variation occurred in C18, C22 and linoleic acids with lesser amounts in the C20 and linolenic acids. The varieties Golden, Argentine, Regina II and Swedish are classed as high, Gute and Arlo as intermediate, and Polish as low erucic acid oils.

The fatty acid composition of the oil from Argentine rapeseed grown in Western Canada was investigated by converting the glyceride esters to methyl esters and distilling the latter in a Podbielniak Heligrid distillation column. Analyses of the fractions showed 6 to 10% more eicosenoic acid and 7 to 10% less erucic acid than was previously reported for rapeseed oils.

With a view to studying the qualitative features and the variations in fatty acid composition of 6 rapeseed (B. campestris and B. napus) and mustard (B. juncea) varieties, an experiment was conducted. Among these varieties, BARI Sarisha-14 presented the value of 168.4 which was recorded the highest. Both BARI Sarisha-11 and BARI Sarisha-14 was found with the highest iodine value of 39.44; and the highest amount of acid value was recorded from BARI Sarisha-11 (1.867). Gas-liquid chromatographic (GLC) method has been used to determine the composition of essential fatty acid in the seeds of Brassica spp. (L.). From the GLC analysis, it was found that erucic acid, oleic acid, linoleic acid and lenolenic acid were the prime fatty acids in all the varieties. Erucic acid was in the range of 41.11 – 51.28%, oleic acid was the highest both in BARI Sarisha-11 and BARI Sarisha- 13 contained (18.69%), while BARI Sarisha-9 contained the highest amount of the unsaturated linoleic (17.75%)  and linolenic (15.83%) acids. Moreover, palmitic acid, stearic acid and archidic acid were also present in small amount.

Rapeseed-mustard is one of the most economically important oilseed crops in India. Speciality oils having high amounts of a specific fatty acid are of immense importance for both nutritional and industrial purposes. Oil high in oleic acid has demand in commercial food-service applications due to a long shelf-life and cholesterol-reducing properties. Both linoleic and linolenic acids are essential fatty acids; however, less than 3% linolenic acid is preferred for oil stability. High erucic acid content is beneficial for the polymer industry, whereas low erucic acid is recommended for food purposes. Therefore, it is important to undertake systematic characterization of the available gene pool for its variable fatty acid profile to be utilized for specific purposes. In the present study the Indian rapeseed-mustard germplasm and some newly developed low-erucic-acid strains were analysed by GLC to study the fatty acid composition in these lines. The GLC analysis revealed that the rapeseed-mustard varieties being commonly grown in India are characterized by high erucic acid content (30–51%) in the oil with low levels of oleic acid (13–23%). However, from among the recently developed low-erucic-acid strains, several lines were identified with comparatively high oleic acid (60–70%), moderate to high linoleic acid (13–40%) and low linolenic acid (< 10%) contents. Work is in progress at TERI (New Delhi, India) to utilize these lines for development of strains with particular fatty acid compositions for specific purposes.

The fatty acid compositions of the oil from 6 varieties of rapeseed grown at 22 stations were determined by gas liquid phase chromatography. Significant differences were found between stations for all fatty acids and between varieties for palmitic, stearic, oleic, linoleic, eicosenoic and erucic acids. The variations for palmitic, stearic, and eicosenoic acids were small, whereas major variations occurred in oleic, erucic and linoleic acids. A correlation coefficient of −0.975 was found between oleic and erucic acids and a prediction equation was determined to calculate oleic acid from the erucic acid content.

The fatty acid composition of retail lamb backfat commonly available in Western Canada was analyzed, including 16 lambs collected from a slaughter plant in central Alberta, and backfat collected from racks and chops imported from Australia (n = 8) and New Zealand (n = 8). Lamb fat from New Zealand was the richest source of vaccenic and rumenic acids. Both New Zealand and Australian lamb were the richest source of n-3 fatty acids. North American lamb was richer in t10-18:1, but a subset had fatty acid compositions similar to New Zealand lamb.

Reciprocal crosses were made between plants of Brassica napus with seed oil containing 40 and 0 per cent erucic acid. Gas liquid chromatographic analysis snowed an erucic acid content of 22 to 24 per cent in the crossed seeds. These results indicate that dominant gene action is absent and that fatty acid composition of the oil is controlled by the developing embryo. Thus the seed on an F1 plant constitutes an F2 population.Methods were developed to determine the fatty acid composition of oil from single seeds and from one cotyledon of an embryo. The analysis of a single cotyledon allows the genotype to be determined one generation earlier than if bulk samples are used, and the remainder of the seed may be grown into a normal plant. It is suggested that this half-seed technique may be used to determine the inheritance of other fatty acids in Brassica, and may also be applied to breeding other oil crops where the embryo, rather than the maternal sporophyte, controls the synthesis of fatty acids.

Fatty acid composition and oil formation were followed in developing seeds of two "linolenic acid lines" of low erucic acid rapeseed (Brassica napus L.) containing above and below normal linolenic acid levels to determine how these different levels of linolenic acid are derived. Under controlled growth room conditions, patterns of fresh weight and dry weight accumulation showed that seeds of both lines matured over the same period of time. During this time, both lines accumulated equivalent amounts of oil. The fatty acid composition of the oils of mature seed of both lines were similar for palmitic (16:0), palmitoleic (16:1), stearic (18:0), linoleic (18:2) and eicosenoic acid (20:1) when expressed either on a percent basis or a weight basis. However, oleic (18:1) and linolenic (18:3) acid were reciprocally related on a percent basis. The seeds of the two lines accumulated different weights of oleic and linolenic acid. Since the accumulation occurred over the same length of time, the difference in oleic and linolenic acid content was caused by different rates of accumulation. Equivalent chlorophyll contents, obtained for both lines, failed to show a relationship between chlorophyll content (indicative of photosynthetic activity) and linolenic acid accumulation.

Aim. Main aim of this research was a comparison of fatty acid composition in seed oil from breeding forms and varieties of hybrid culture tyfon (B. rapa ssp. oleifera f. biennis × (B. rapa ssp. rapifera × B. rapa ssp. pekinensis)) produced in M.M. Gryshko Natl. Botanical Garden of Natl. Academy of Sci. of Ukraine and its parental genotypes: turnip rape and hybrid Holland greens. Methods. Biochemical analysis of oil content as well as chromatographic analysis of fatty acid composition of tyfon were conducted out. Results. Oil fatty acids profiles of tyfon (B. rapa ssp. oleifera f. biennis × (B. rapa ssp. rapifera × B. rapa ssp. pekinensis)) were determined. The highest content of erucic acid was 42.8 % in cultivar Fitopal, the highest content of oleic acid (20.02 %) was in oil of breeding form EOTFVS. Highest content of gondoic acids was indentified in oil of breeding form EOTFV (11.46 %). Conclusions. Taking in account the results of chromatographic analysis the best genotypes for biodiesel production were identified: cultivar Fitopal and breeding form EOTFVS due to their highest content of erucic acid (42.8 % and 41.63 %) and lowest content of linolenic acid (6.99 % and 6.6 %).
