This paper reports changes in the fatty acid profiles of the hemp seed oil of two breeding populations, Kolaj and Fibrol, after five and seven years of selection for high oil content. While the original variety Kompolti had a 3:1 ratio of linoleic acid to linolenic acid, which has been claimed to be optimal for human nutrition, the selected population of Kolaj (improved Kompolti) shows a ratio close to 4:1.The highest ratio of increase (r.i.) was 1.45, determined for γ-linolenic acid in Fibrol (improved Fibrimon 21-63). Another significant change was the 0.49% (r.i. 1.21) increase in stearic acid in this variety, along with a 3.16% (r.i. 1.1) increase in total oil content. In Kolaj the 5.87% (r.i. 1.2) increase in oil content was accompanied by a 1.76 % (r.i. −1.28) decrease in palmitic acid and by decreases of 2.98% and 0.18% (r.i. −1.15 and −1.16), respectively, in the α- and γ-linolenic acid contents.

Sixty individually penned steers (380 ± 39 kg) were fed barley-based finishing diets containing 0 (control), 9 or 14% full-fat hemp seed (HS) and effects on performance and tissue fatty acid profiles were assessed. At harvest, samples of pars costalis diaphragmatis (PCD) and brisket fat were collected from each carcass. Feeding HS did not affect (P > 0.25) dry matter intake (DMI), average daily gain (ADG), or gain feed-1. Carcass traits were also unaffected (P > 0.35) by treatment. Feeding HS linearly increased (P < 0.001) proportions of C18:0, C18:3 and C18:1 trans-9 in PCD, and 18:2 trans, trans in both PCD and brisket fat. As well, HS linearly increased cis-9 trans-11 CLA (P < 0.001), total saturates (P = 0.002) and polyunsaturated fatty acids (PUFA) (P = 0.01) in PCD. The presence of C20:4, C20:5 and C22:5 was detected only in tissues of cattle supplemented with HS (P < 0.06). Linear reductions (P < 0.002) in C16:1 cis, C17:1, C18:1 cis -9, C20:1, and total unsaturates in PCD, as well as linear decreases in C17:0 (P = 0.04) and C17:1 (P < 0.001) in brisket fat were observed when HS was fed. Levels of HS up to 14% of diet ary DM exerted no detrimental effect on the growth or feed efficiency of cattle as compared to cattle fed a standard barley-based finishing diet. Including HS in the diet had both positive (increased CLA content) and negative (increased trans and saturated fats) effects on fatty acid profiles of beef tissues.

Abstract The fatty acid composition of seed oils of eight Ranunculaceae was determinated in order to characterize new sources of gamma-linolenic acid. Fatty acids were identified as fatty acid methyl esters (FAME) by capillary gas-liquid chromatography (GC) and capillary GC-Fourier transform infrared spectroscopy (FTIR). For trienic FAME the use of a cyanopropyl-polysiloxane stationary phase (CP-Sil 88) allowed the separation with high resolution of methyl ester of columbinic acid (trans-5,cis-9,cis-12 18:3) and gamma-linolenic acid (cis-6,cis-9,cis-12 18:3). The results confirmed the presence of columbinic acid in Thalictrum seed oils, and that of gamma-linolenic acid in Anemone and related species seed oils. The taxonomic subdivision of Ranunculaceae into sub-families and tribes, which resulted from morphological considerations, did not account for the above results.
