Bioactive Compounds, Antioxidant Properties, and Cosmetic Applications of Selected Cold-Pressed Plant Oils from Seeds
Plant oils are currently not only an essential element of the healthy eating pyramid, but also a valuable cosmetic material, which, in line with the eco-friendly trends of recent years, is effectively replacing petroleum-derived fatty ingredients. The fatty acids, phenolic compounds, pigments, and vitamins (e.g., A and E) present in plant oils contribute to their health-promoting properties, including antioxidant activity. This study assessed the contents of carotenoids and chlorophylls, as well as the antioxidant properties of 10 selected plant oils. Fenugreek seed oil was shown to have the highest total content of carotenoids, and the most β-carotene. Chokeberry and rosehip oils also contained large amounts of provitamin A, in comparison to the other oils tested. Lycopene was the dominant compound in black currant and rosehip seed oils. Among chlorophyll pigments, elderberry oil had the highest content of chlorophyll a, while black currant oil had large amounts of both chlorophyll a and chlorophyll b. The antioxidant properties of the cold pressed oils obtained from selected seeds and fruit stones, assessed by electron paramagnetic resonance (EPR) spectroscopy as the ability to interact with the DPPH (2,2-diphenyl-1-picrylhydrazyl) free radical, can be ranked as follows: pomegranate > fenugreek > poppy > black currant > chokeberry > rosehip > perilla > elderberry > carrot > fig. The results of this study showed that these plant oils are valuable natural materials with antioxidant properties, which can be an important complement to synthetic antioxidants due to their additional skin care properties.
