Antioxidant Potential

Plodovi grejpfruta značajno se ističu bogatim nutritivnim sastavom, posebice sadržajem vitamina C, polifenolnih spojeva i snažnom antioksidacijskom aktivnosti. Sastav i sadržaj fitokemikalija uvelike ovisi o genetskim svojstvima vrste odnosno sorte. Stoga je i cilj ovog istraživanja bio utvrditi fizikalno-kemijska svojstva, sadržaj bioatkivnih spojeva i antioksidacijski potencijal plodova grejpfruta dviju različitih sorti: 'Marsh Seedless' i 'Natzumikan'. Obje sorte grejpfruta ubrane su u nasadu agruma na području Opuzena. Istraživane sorte ne razlikuju se značajno u sadržaju ukupne suhe tvari (prosječna utvrđena vrijednost 11,55%), topljive suhe tvari (prosječna utvrđena vrijednost 9,89%) kao ni u sadržaju vitamina C (prosječna utvrđena vrijednost 42,92 mg/100 g svježe tvari). No, značajnije razlike utvrđene su u sadržaju polifenolnih spojeva prilikom čega su kod sorte 'Natzumikan' utvrđene čak 66% više vrijednosti ukupnih fenola, 76% više ukupnih flavonoida i 54% više ukupnih neflavonoida u usporedbi sa sortom 'Marsh Seedless'. Također, sorta 'Natzumikan' imala je i značajnije veći antikodiacijski kapacitet (1,68 mmol TE/L). Temeljem svega može se zaključiti kako su plodovi grejpfruta značajan izvor vrijednih fitokemikalija, značajnih za ljudsko zdravlje.

Food Ingredient

The fatty acid (FA), polyphenol content and evaluation of the antioxidant capacity of exhausted Myrtus communis berries (EMB) resulting from the production of myrtle liqueur were assessed. All parts of the exhausted berries exhibited high concentrations of carbohydrates, proteins, lipids and phenolic compounds. The lipid fraction contained a high amount of poly unsaturated fatty acids (PUFA), mainly represented by linoleic acid (>70%). Of the phenolic acids evaluated by liquid chromatography/mass spectrometry, ellagic acid was the most predominant (>50%), followed by gallic and quinic acids. Quercetin and quercetin3-O-rhamnoside were the most abundant flavonoids. The seed extracts showed a higher antioxidant potential than the pericarp extracts; the same trend was observed for total phenolic compounds evaluated by spectrophotometric assay. The overall high content of bioactive compounds and the high antioxidant potential of this byproduct sustain its suitability for a number of industrial applications, such as a food ingredient in novel foods, an additive in cosmetic formulations or a component of animal feed formulations.

Vegetation Water

In the Rural Development Plan (2014–2020), the European Commission encouraged the conversion and supported the maintenance of organic farming. Organic olive oil (bioEVOO) production involves the use of environmentally sustainable fertilizers and the recycling of olive pomace (Pom) and olive vegetation waters (VW) to reduce the environmental impact of these wastes. An ecofriendly way to recycle olive wastes is to reuse them to extract bioactive compounds. In this study, the total phenolic compounds content, their profile and dosage, the antioxidant action in oil, pomace, and vegetation water was evaluated when the Trichoderma harzianum M10 was used as a biostimulant in agriculture. Two spectrophotometric tests (2,2-diphenyl-1-picrylhydrazyl (DPPH) and 2,2′-azinobis (3-ethylbenzothiazoline-6-sulfonic) acid (ABTS)) evaluated the antioxidant potential of samples, a spectrophotometric method estimated total phenolic content, and an Ultra-High-Performance Liquid Chromatography (UHPLC)–Orbitrap method evaluated the phenolics profile. Our results showed that the biostimulation improved the antioxidant potential and the total concentration of phenolics in the bioEVOO and bio-pomace (bioPom) samples and mainly enhanced, among all classes of phenolic compounds, the production of the flavonoids and the secoiridoids. Moreover, they demonstrated the Trichoderma action in the mevalonate pathway to produce phenols for the first time. The decisive action of the Thricoderma on the production of phenolic compounds increases the economic value of the waste materials as a source of bioactive compounds useful for the pharmaceutical, cosmetic, and food industries.

Cellular Lipid Accumulation

Wheat germ (WG) is a by-product of wheat milling and comprises many bioactive compounds. This study aimed to compare the antioxidant and antilipidemic effects of different WG extracts (WGEs) by analyzing candidate bioactive compounds such as carotenoids, tocopherols, γ-oryzanol, and biogenic amines by reversed-phase high-performance liquid chromatography. Antioxidant activity was determined using the ABTS, DPPH, and FRAP assays. The antilipidemic effect was evaluated in palmitic acid-induced steatosis in HepG2 hepatocytes and 3T3-L1 adipocytes. Cellular lipid accumulation was assessed by Oil Red O staining and a cellular triglyceride content assay. All analyzed WGEs showed significant antioxidant potential, although some bioactive compounds, such as carotenoids, tocopherols, and γ-oryzanol, were the highest in the ethanol extract. Correlation analysis revealed the antioxidant potential of all identified biogenic amines except for spermidine. Ethanol and n-hexane extracts significantly inhibited cellular lipid accumulation in cell models. These results suggest that WGEs exhibit promising antioxidant potential, with a variety of bioactive compounds. Collectively, the findings of this study suggest that bioactive compounds in WGEs attenuate plasma lipid and oxidation levels. In conclusion, WG can be used as a natural antioxidant and nutraceutical using appropriate solvents and extraction methods.
