“…Regular sunflower oil contains 69% linoleic acid, 20% oleic acid and 11% saturated fatty acids. However, these percentages vary according to the growth environment and cultivated genotype (Alberio et al, 2016, Angeloni et al, 2017. Similar results were found by Reginato Neto et al (2016), when evaluating the effect of the environment on the quality of sunflower oil produced in Campinas, Sã o Paulo.…”

It has been suggested that fatty acid balance in standard sunflower oil may be influenced by the genotype of the plant or by variation in environmental growth conditions. Therefore, this study analysed aspects of sunflower productivity and oil quality obtained from achenes of plants cultivated in a semi-arid environment, resulting from seed obtained from other regions with different edaphoclimatic characteristics. The experiment was conducted between February and May, in a Brazilian semi-arid area. At 90 days after sowing (DAS), the physiological maturation period, tissue was harvested, and the yield of plant green matter, oil and oil per hectare was evaluated. A comparative analysis of the oil content of achenes before and after planting (parental v progeny) was performed. The experiment was conducted in a randomized block design of 4 treatments (genotypes), Embrapa122, BRSG01, Helio253 and Helio250, and 4 replications, for a total of 16 experimental plots, with each plot constituting 8 plants. In this study, sunflowers were produced in the climatic conditions of the Brazilian semi-arid region with biomasses, achenes and oil contents that were different from other crop productions in the country, providing the possibility of obtaining oil with a distinct chemical composition.

“…The genetic background effect was registered in the fatty acid composition when comparing P or NM1‐NILs. According to results, the genetic variability in the oleic acid content reported by several authors in high oleic sunflower lines carrying the P mutation and hybrids may also be attributed to genetic background diversity. In the present work, the NM1‐NIL group reached the highest oleic acid content when compared with the P‐NIL group with a minimum of 907 g kg −1 .…”

“…In this sense, previous work reported that a sunflower NIL carrying the new high oleic mutation 29066 showed higher fatty acid stability and ultra‐high oleic quality across environments, compared to the respective sunflower P‐NIL . Although a possible effect of genetic background on the oleic acid content after changes of minimum night temperature (MNT) was documented in traditional sunflower hybrids and in high oleic sunflower hybrids carrying the P mutation, this effect was not empirically proved in NILs carrying the P or the NM1 mutation. Likewise, the genetic background effect on NILs carrying these mutations was not tested either.…”

“…The composition and content of FA was often affected by environmental factors, especially temperature. Angeloni et al (2017) indicated that oleic acid percentage in sunflower oil was closely related to minimum night temperature during a short period of grain filling. Rondanini et al (2014) found that temperature during oil synthesis was negatively related to final oil concentration of olive.…”

Wild Paeonia ludlowii is considered as a traditional ornamental plant, but its flowers and seed oils are edible with important economic values, and the variation of nutrients, fatty acid composition in wild populations is scarcely known. Flowers and seeds of P. ludlowii were collected from two wild populations for evaluating the nutrients in flowers, composition of fatty acids in seed oils and the antioxidant activity. The flowers contained high composition of proteins, carbohydrates, amino acids, total flavonoids, phenolic compounds and essential minerals. Seed oil yield reached up to 21.95% using supercritical CO2 fluid extraction, and it contained 14 fatty acids (up to 93.35 g/100g seed oil), especially the unsaturated fatty acids (oleic acid, linoleic acid and α-linolenic acid) was up to 88.69% with low ω6/ω3 ratios of 0.58. The antioxidant capacity can be arranged in the order of trolox > flower extracts > seed oil according to the DPPH and ABTS free radical assay. Contents of nutrient in flowers and fatty acids in seed oils were significantly different between two wild populations due to the impact of different growing environments. These results indicate that flowers and seed oils of P. ludlowii are potential food resources in human diets.
