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.

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.

The Impact

The variation in polyunsaturated fatty acid content of walnut (Juglans regia L.) oils was determined by analysis of samples isolated from specimens growing in four germplasm collections [California (55 cultivars), Washington (64 seedlings), China (12 cultivars), and France (20 cultivars)]. In addition, the impact of within-state geographic differences on oil composition was examined by comparing samples from three California cultivars (`Ashley', `Hartley', and `Franquette') grown in three locations. Local environmental effects on oil composition of `Chico' were also examined by comparing 1) samples collected from shaded and sun-exposed locations of the same trees and 2) samples collected from trees subjected to three irrigation regimes. Polyunsaturated fatty acid content, as a percentage of total fatty acids, ranged from 47.2% in nuts from PI 142323 from France to 81.0% in `Ashley' from California. However, our data indicate that environment, genotype, nut maturity, and their interactions all contribute significantly to variation in the degree of unsaturation of walnut oil.

High Saturated Fatty Acid

SUMMARY The genetic control of the high saturated fatty acid content in sunflower seed oil has been studied in the high palmitic acid (C16:0) mutant line CAS-5, and in the high stearic acid (C18:0) mutant line CAS-3. This review summarizes the pertinent results. The high saturated fatty acid content in sunflower seed oil is controlled by partially recessive alleles at two loci (Es1, Es2) for the high C18:0 content and at three loci (P1, P2, P3) for the high C16:0 content. The high C16:0 and the high C18:0 traits are not inherited independently. When their combined segregation was studied, the expected phenotypic expression of both high C16:0 and high C18:0 levels was not observed. This fact was attributed to the existence of an epistatic effect of the loci controlling the high C16:0 trait on the loci controlling the high C18:0 trait. The results obtained indicate that sunflower hybrids with a high saturated fatty acid content in their seed oil can be developed and will be in cultivation in a few years.
