Abstract

The bioactive compounds and ‘‘in vitro’’ antioxidant activity measured by three antioxidant assays
of some traditional and non-traditional cold-pressed edible
oils from Macedonia were object of this study. The fatty
acid composition showed dominance of monounsaturated
oleic acid in ‘‘sweet’’ and ‘‘bitter’’ apricot kernel oils with percentages of 66.7 ± 0.5 and 57.8 ± 0.3%, respectively. The most dominant fatty acid in paprika seed oil was polyunsaturated linoleic acid with abundance of
69.6 ± 2.3%. The most abundant tocopherol was c-tocopherol
with the highest quantity in sesame seed oil
(57.6 ± 0.1 mg/100 g oil). Paprika seed oil, sesame seed
oil and sweet apricot oil were the richest source of phytosterols. DPPH assay was the most appropriate for the
determination of the antioxidant activity of cold-pressed
sunflower oil due to high abundance of a-tocopherol with a
level of 22.8 ± 1.1 mg/100 g of oil. TEAC assay is the
best for the determination of the antioxidant activity of
sesame seed oil and paprika seed oils as the richest sources
of phenolic compounds. b-carotene assay was the most
suitable assay for oils obtained from high pigmented plant material. Triacylglycerols and phytosterol profiles can be
used as useful markers for the origin, variety and purity of
the oils.
