Optimization of phenolic compound extraction from Tunisian squash by-products: A sustainable approach for antioxidant and antibacterial applications.

The valorization of agricultural by-products is a key strategy for environmental sustainability. This study focuses on optimizing the extraction of phenolic compounds from by-products (peels, fibrous strands, and seeds) of two Tunisian squash landraces (e.g.

Lipid Oxidation and Barrier Properties of the Coated Freeze-Dried Chicken Meat with Gelatin-Chitosan Film Enriched with Rosemary ( L.) Extract.

The study aimed to evaluate the quality of the coated freeze-dried chicken meat using gelatin-chitosan film enriched with Tunisian rosemary extract. The quality was evaluated on the basis of physical and barrier properties, as well as lipid oxidation for coated and uncoated chicken meat. Chicken breast meat was cut into small pieces, pasteurized, and coated with the active film solution.

Enhancing grape maturation and antioxidant profiles in grapes () using nanoemulsion of essential oil.

The growing demand for eco-friendly agricultural solutions has led to increased interest in plant-based biostimulants. This study evaluates the potential of a nanoemulsion of essential oil (NANO-TA) as a natural elicitor to enhance the technological and phenolic maturity of Red Globe grapes in an organic cultivation system. Vine plants were treated with NANO-TA, formulated from an essential oil rich in α-pinene (17.

Eco-friendly extraction of hesperidin from citrus peels: a comparative study of Soxhlet, ultrasound-assisted, and microwave-assisted methods for improved yield and antioxidant properties.

This study compares Soxhlet extraction, ultrasound-assisted extraction (UAE), and microwave-assisted extraction (MAE) for isolating hesperidin from citrus peels. UAE achieved the highest yield (89.7%) and demonstrated favorable kinetic parameters (rate constant: 0.

Enhancing antioxidant yield from carob ( L.): evaluating the efficacy of maceration and ultrasound-assisted methods.

  Our study aimed to optimize carob antioxidant extraction for use in the food, cosmetic, and pharmaceutical industries. Maceration investigated ethanol concentration, extraction temperature, and time, while ultrasound-assisted extraction examined ethanol concentration, ultrasound power, and time. A central composite design with 19 experimental points assessed the influence of variables on total yield, total phenolic content, and antioxidant activity.

Protective potential of onion eco-extract: safeguarding chicken patties from oxidative deterioration.

Onions contain valuable phytochemical compounds, including quercetin derivatives. This study explores the potential of onion extract as a natural additive in chicken patties. The optimized conditions involved sonication at 80% for 5 min with a 75% ethanol concentration.

Quality of Edible Sesame Oil as Obtained by Green Solvents: In Silico versus Experimental Screening Approaches.

The present study aimed to investigate the qualitative and quantitative performance of five green solvents, namely 2-methyltetrahydrofuran (MeTHF), cyclopentyl methyl ether (CPME), -cymene, -limonene and ethanol to substitute -hexane, for sesame seed oil extraction. In fact, both CPME and MeTHF gave higher crude yields than -hexane (58.82, 54.

Green Solvent to Substitute Hexane for Bioactive Lipids Extraction from Black Cumin and Basil Seeds.

A comparative study of bioactive lipids extraction from black cumin ( L.) and basil ( L.) seeds using conventional petroleum-based solvent and green solvent 2-methyltetrahydrofuran (MeTHF) was performed.

Crude Extract as a Powerful Natural Herbicide and Insight into the Mode of Action of Its Bioactive Molecules.

The use of chemical herbicides could not only potentially induce negative impacts on the environment, animals, and human health, but also increase the weed resistance to herbicides. In this context, the use of plant extracts could be an interesting and natural alternative to chemical products. It is important to understand the mode of action of their bioactive compounds.

Chemical composition and antioxidant potential of essential oil and methanol extract from Tunisian and French fennel (Foeniculum vulgare Mill.) seeds.

This study was designed to examine the effect of provenance on the phytochemical and antioxidant properties of essential oil and methanolic extract from Tunisian and French fennel seeds (FFS). Analysis of the essential oil showed that although the same main compounds were found in Tunisian and FFS cultivars, some differences were present in their proportions allowing to classify them in two chemotypes. The first class was composed by trans-anethole (63.

Does root powder have an effect against CCl-induced hepatotoxicity in rats: a protective and curative approach.

This study was conducted to investigate potentially protective and curative effects of root (turmeric) powder on CCl-induced hepatotoxicity in rats. Turmeric was administered before (preventive effect) or after (curative effect) treatment with CCl. Total phenolic and flavonoid levels were 26.

Relation between salt tolerance and biochemical changes in cumin (Cuminum cyminum L.) seeds.

In this study, the effects of salinity on growth, fatty acid, essential oil, and phenolic composition of cumin (Cuminum cyminum L.) seeds as well as the antioxidant activities of their extracts were investigated. Plants were treated with different concentrations of NaCl treatment: 0, 50, 75, and 125 mmoL.

Antioxidant and antimicrobial phenolic compounds from extracts of cultivated and wild-grown Tunisian Ruta chalepensis.

The antioxidant and antibacterial activities of phenolic compounds from cultivated and wild Tunisian Ruta chalepensis L. leaves, stems, and flowers were assessed. The leaves and the flowers exhibited high but similar total polyphenol, flavonoid, and tannin content.

Metabolite profiles of essential oils and molecular markers analysis to explore the biodiversity of Ferula communis: Towards conservation of the endemic giant fennel.

Giant fennel (Ferula communis L.) is well known in folk medicine for the treatment of various organ disorders. The biological importance of members of genus Ferula prompted us to investigate the leaves of the endangered Tunisian medicinal plant F.
