Eucalyptus globulus is planted extensively for pulp, paper and wood production. Although bioactive compounds obtained from its biomass are used as cosmetics ingredients, the skin effects were not yet fully explored. In order to fill this gap, work aimed study protective effect against damage provided by essential oil (EO) hydrodistillation of leaves, an extract residual water (HRW). The major compound identified in EO was 1,8-Cineole, phenolic acids HRW included gallic acid main constituent....
Chritmum maritimum, sea fennel, is a facultative halophyte used in salads, soups, and sauces, as well to prepare medicinal juices aqueous extracts (AE) treat several ailments. Its essential oil (EO) spice aromatizing. In this work, the nutritional (crude protein, fiber, lipids, ashes content) HPLC-PDA phenolic profiles were determined. Furthermore, antioxidant potential of infusion decoction, antibacterial activity both, AE EO, assessed against food-contaminating bacteria. The composition EO...
Cymbopogon citratus, an herb known worldwide as lemongrass, is widely consumed aromatic drink, and its fresh dried leaves are currently used in traditional cuisine. However, little about the mechanism of action C. namely, anti-inflammatory effects dietary components. Because nitric oxide (NO), produced large quantities by activated inflammatory cells, has been demonstrated to be involved pathogenesis acute chronic inflammation, we evaluated infusion from well polyphenolic...
Edible films and coatings allow preserving fresh processed food, maintaining quality, preventing microbial contamination and/or oxidation reactions increasing the shelf life of food products. The structural matrix edible is mainly constituted by proteins, lipids or polysaccharides. However, it possible to increase bioactive potential these polymeric matrices adding phenolic compounds obtained from plant extracts. Phenolic are known possess several biological properties such as antioxidant...
Currently, the high food demand led to a mass agriculture practices, whereas crop productivity is one of major concerns for producers.However, intensification use synthetic fertilizers has serious harmful impacts human health and environment.The quest novel natural agricultural products current trend, hence seaweed polysaccharide bioactivity can contribute this pursuit.The principal carbohydrates (agar, carrageenan alginate) were extracted chemically characterized from five red seaweeds,...
Blueberries, red fruits enriched in polyphenols and fibers, are envisaged as a promising nutraceutical intervention plethora of metabolic diseases. Prediabetes, an intermediate state between normal glucose tolerance type 2 diabetes, fuels the development complications, including hepatic steatosis. In previous work, we have demonstrated that blueberry juice (BJ) supplementation benefits glycemic control lipid profile, which was accompanied by amelioration mitochondrial bioenergetics. The...
Diplotaxis muralis (L.) DC (Brassicaceae) is an edible plant commonly used in Mediterranean diets. This study investigates its nutritional composition, secondary metabolites, and antioxidant activity. The results show that this rich fibre essential minerals. Analysis of amino acids shows a diverse profile, with glutamic acid aspartic being the most abundant. Regarding fatty acids, α-linolenic was identified as predominant. Importantly, levels toxic metals such cadmium, lead, mercury were...
Fragaria vesca L. (F. vesca), popularly known as wild strawberry, is a plant from the Rosaceae family, found in temperate and subtropical areas of northern hemisphere. F. leaves have been shown to antiseptic, emollient, dermatological protection properties, due presence bioactive compounds, such flavonoids, phenolic acids, ellagitannins, proanthocyanidins. In this study, extract was obtained by an optimized extraction process, characterized HPLC, ROS scavenging activity, cytotoxicity assays...
Luteolin is a dietary flavonoid with medicinal properties including antioxidant, antimicrobial, anticancer, antiallergic, and anti-inflammatory. However, the effect of luteolin on liver X receptors (LXRs), oxysterol sensors that regulate cholesterol homeostasis, lipogenesis, inflammation, has yet to be studied. To unveil potential as an LXRα/β modulator, we investigated by real-time RT-PCR expression LXR-target genes, namely, sterol regulatory element binding protein 1c (SREBP-1c) in...
Research on bioactive compounds is essential to improve human health; promote adequate nutrition; drive innovation in the food, agricultural and biotechnology industries; contribute preservation of environment. The genus Diplotaxis (Brassicaceae) currently comprises around forty species, some which are edible, particularly tenuifolia (wild rocket), erucoides (wall muralis (annual wall viminea (perennial simplex. leaves these species rich fiber minerals, such as calcium, iron, potassium,...
