“…Bail et al (2008) investigated Austrian GSO antioxidant capacity (from 9.0 to 116.0 µM TE 100 g -1 of oil) and Fernandes et al (2013) worked with ten different oils from many varieties of Portuguese grapes, founding a range from 33.4 to 48.9 mmol TE 100 mL -1 of oil.…”

“…The phenol extraction was carried out with a methanolic extract obtained according to Bail et al (2008) and quantification was based on the colorimetric method by Hills & Swain (1959) using Folin-Ciocalteau adapted to a microplate reader (Biotek ® , Synergy HT model, Winooski, VT, USA). Absorption was measured at 720 nm.…”

“…TEAC measurements were achieved by comparing decreased absorption after using 20 µL of GSO extract (Bail et al, 2008), reagent blank or Trolox standard, respectively, with 200 µL of 7 mM ABTS + . Absorbance was monitored at 734 nm 6 min after the addition of reactant at 25 °C.…”

“…For the lipophilic method, samples were diluted in acetone:water (1:1) with β-cyclodextrin. For the hydrophilic method, methanolic extract was used according to Bail et al (2008) and then diluted in ethanol. An automated ORAC assay was carried out on a microplate reader at 493nm (filter 485/20) and an emission of 515 nm (filter 528/20).…”

Chemical composition of cold pressed Brazilian grape seed oil

Grape seed oil (GSO) is an important by-product of the wine-making industry which has received attention as an alternative source of vegetable oils; its chemical compounds can be influenced by agricultural practices and industrial processing. Knowledge of the composition of Brazilian GSO is scarce; thus, this study aimed to analyze the chemical characteristics, as well as the antioxidant activity of these oils. GSO samples were obtained from Brazilian markets and showed significantly high amounts of phenolic, γ-tocotrienol and phytosterols as well as, the presence of several volatile compounds. Based on these results, is possible to show that oils exhibited good antioxidant activity. Therefore, it can be inferred that Brazilian GSO had a considerable content of phytochemical compounds with biological activity, which allows its association with other vegetable oils.

“…Grape seed oil has been observed to have an effect on decreasing the fat content of other animals bodies (lambs) (20). While more studies are necessary to clarify the exact mechanism of action, we could hypothesize these effects to be related to phenolic compounds that are present in grape seed oil (21). Polyphenolic compounds that are structurally related to chalcone, including flavonoids (22) and coumarin chalcones (23) have been reported to improve lipid profile in high-fat fed or hyperlipidemic animals.…”

Objective: Acarbose and trans-chalcone are glucosidase inhibitors whose beneficial effects have been demonstrated in diabetes. The present study aimed at investigating their potential effects in obesity. Materials and methods: NMRI male mice (n = 48) were subjected to a high fat diet for four weeks, which induced an initial state of obesity. One control group was given normal rodent diet. Obese animals were then switched to normal rodent diet, and divided to four groups (n = 12 in each): untreated, sham (receiving grape seed oil), and experimental groups receiving acarbose and trans-chalcone (12 mg/kg) during eight weeks. Body weight, blood glucose and other biochemical parameters including triglycerides (TG), cholesterol, HDL, AST, and ALT were measured, as well as leptin, adiponectin, TNF-α, and total antioxidant capacity (TAC). Histological studies were performed on adipose cells and liver tissue samples. Results: All factors were affected in a positive manner by acarbose, save for body weight, blood sugar and leptin levels, on which acarbose effects, although observable, were not statistically significant. Grape seed oil, used as a solvent for trans-chalcone was found to possess significant effect on TG and TAC, and had beneficial effects on other factors including liver enzymes and cholesterol. Trans-chalcone effects were significant on HDL, leptin and ALT. All compounds seemed to be able to affect fat deposition in liver tissue, and decrease the size of adipose tissue cells to some extent. Conclusion: In conclusion, the tested compounds were able to affect lipid accumulation in tissues and influence adipokines, which may result in an enhanced state with regard to inflammation and oxidative stress.

In this study, the aim was to characterize the physicochemical properties and some bioactive compounds of expeller‐pressed oils of five registered poppy seed varieties (TMO–1, Ofis–8, Ofis–96, Ofis–95, Ofis–3) grown in Turkey. The amounts of total carotenoids, chlorophylls, phenols, and antioxidant activities of oils ranged between 0.08–0.24 mg 100 g−1, 0.03–9.04 mg pheophytin a kg−1, 3.41–8.57 mg gallic acid equivalent 100 g−1, and 5.60–7.33 mM Trolox equivalent 100 g−1, respectively. The most abundant fatty acid in poppy seed oils was linoleic acid (69.85–74.02%), followed by oleic acid (13.98–16.99%), and palmitic acid (8.51–9.75%). In addition, poppy seed oils were rich in β–sitosterol (133.47–153.42 mg 100 g−1), campesterol (45.36–58.60 mg 100 g−1), and δ–5–avenasterol (28.21–39.40 mg 100 g−1). High amounts of γ–tocopherol and α–tocopherol were detected. This research is the first study, which identified and quantified the polyphenol, β–carotene, and lutein compounds of expeller–pressed poppy seed oils by HPLC. Tyrosol, apigenin, syringic acid, 3–hydroxytyrosol, luteolin, p–coumaric acid, quercetin, ferulic acid, sinapic acid, and veratric acid were detected in expeller‐pressed poppy seed oils.
