(+)-(E)-Chrysanthenyl Acetate: A Molecule with Interesting Biological Properties Contained in the Anthemis secundiramea (Asteraceae) Flowers
2020
Anthemis secundiramea is a perennial herb native widespread throughout the Mediterranean basin. The oil obtained from the flowers of this plant has antimicrobial properties against gram-positive and -negative bacteria, and inhibits the biofilm formation. The extract of A. secundiramea also has antioxidant activity&mdash
Interactive Effects of Genotype and Molybdenum Supply on Yield and Overall Fruit Quality of Tomato
2019
Molybdenum (Mo) is an essential trace element for plant growth, development, and production. However, there is little known about the function and effects of molybdenum in tomato plants. The present study assessed the influences of different Mo concentrations on four tomato F1 hybrids (“Bybal” F1, “Tyty” F1, “Paride” F1, and “Ornela” F1) grown using a soilless system with different Mo levels [0.0, 0.5 (standard NS), 2.0, and 4.0 μmol L−1, respectively]. The crop yield, plant vigor, fruit skin color, TA, fruit water content as well as the accumulation of SSC, and some antioxidant compounds such as lycopene, polyphenols and ascorbic acid were evaluated. The minerals concentration, including n…
Effects of plant type and calcium cyanamide dosage on yield, nutritional and nutraceutical traits of strawberry in Sicily
2021
In the Mediterranean area, strawberry is usually set up by using bare-rooted plants, fresh plug plants or cold-stored plants, achieving different fruit ripening earliness and crop performance. Strawberry plants can be combined with various cultivation practices to improve strawberry fruit production and quality. Calcium cyanamide (CaCN2) is well-acknowledged as a fertilizer used in the horticulture sector. Its use can enhance the soil fertility, prevent soil acidification, and improve crop production and fruit quality. This work evaluated the effects of different pre-transplant CaCN2 dosages on bare-rooted plants, fresh plug plants or cold-stored plants. Coldstored plants with 400 kg ha(-1)…
Hairy Garlic (Allium subhirsutum) from Sicily (Italy): LC-DAD-MSn Analysis of Secondary Metabolites and In Vitro Biological Properties
2020
Allium subhirsutum, known as hairy garlic, is a bulbous plant widespread in the Mediterranean area and locally used as a food and spice. In the present study, the chemical profile of the ethanolic extracts from bulbs (BE) and aerial parts (APE) were analyzed by HPLC-ESI-MSn, and antioxidant properties were evaluated by DPPH, ABTS and TEAC assays. The traditional use in the diet, and the well documented biological activity of Allium species suggest a potential as a new nutraceutical. For this reason, the potential usefulness of this food can be considered in the treatment and prevention of degenerative Alzheimer disease. For this reason, acetylcholinesterase inhibitory property was investiga…
Chemical Composition of Green Pea (Pisum sativum L.) Pods Extracts and Their Potential Exploitation as Ingredients in Nutraceutical Formulations
2021
Agro-industrial wastes contain a large number of important active compounds which can justify their use as innovative ingredients in nutraceutical products. This study aimed to provide a complete analysis of active molecules, namely (poly)phenols in pea pods water-based extracts, through a UHPLC-Q-Orbitrap HRMS methodology. Data showed that 5-caffeoylquinic acid, epicatechin, and hesperidin were the most relevant (poly)phenols found in the assayed extracts, with a mean value of 59.87, 29.46, and 19.94 mg/100 g, respectively. Furthermore, changes in antioxidant capacity and bioaccessibility of total phenolic compounds (TPC) after the simulated gastrointestinal (GI) process were performed usi…
Pulsed electric field (PEF) as an efficient technology for food additives and nutraceuticals development
2020
Abstract The use of pulsed electric field (PEF) technology has been extensively investigated in the area of food pasteurization and gene transfection. In the recent years the technology has also shown promising application in the development of various plant- and microorganism-based added-value compounds. The main working principle of PEF is electroporation or electropermeabilization of cell membranes. The pretreatment of biological tissues with PEF improves mass transfer during solvent extraction of metabolites and thereby increases the extraction efficiency. Moreover, the application of PEF at lower intensity has shown to induce stress on the biological tissues that in turn improves the a…
Valorization of kiwi agricultural waste and industry by-products by recovering bioactive compounds and applications as food additives : a circular ec…
2021
Currently, agricultural production generates large amounts of organic waste, both from the maintenance of farms and crops (agricultural wastes) and from the industrialization of the product (food industry waste). In the case of Actinidia cultivation, agricultural waste groups together leaves, flowers, stems and roots while food industry by-products are represented by discarded fruits, skin and seeds. All these matrices are now underexploited and so, they can be revalued as a natural source of ingredients to be applied in food, cosmetic or pharmaceutical industries. Kiwifruit composition (phenolic compounds, volatile compounds, vitamins, minerals, dietary fiber, etc.) is an outstanding basis…
Mushroom-Based Supplements in Italy: Let’s Open Pandora’s Box
2023
Mushrooms and derivates are well known to the scientific community for having different health benefits and exhibit a wide range of pharmacological activities, including lipid-lowering, antihypertensive, antidiabetic, antimicrobic, antiallergic, anti-inflammatory, anticancer, immunomodulating, neuroprotective and osteoprotective actions. In Europe, medical mushrooms are mainly marketed in the form of food supplements as single components or combined with other nutraceuticals. In this context, the first peculiarity that distinguishes it is the safety established through the “history of consumption” that characterizes that mushroom. However, the cultivation of medicinal mushrooms on a large s…
The clinical impact of an extra virgin olive oil enriched mediterranean diet on metabolic syndrome: Lights and shadows of a nutraceutical approach
2022
For years it has been established that the only truly effective treatment of metabolic syndrome (MS) is lifestyle modification to prevent its cardiovascular (e.g., coronary artery disease and atherosclerosis), metabolic (e.g., diabetes mellitus), and hepatic (e.g., steatosis and non-alcoholic steatohepatitis) complications. The focal points of this approach are to increase physical activity and intake of a diet characterized by high quantities of fruits, vegetables, grains, fish, and low-fat dairy products, the so called mediterranean diet (MD); however, the added value of MD is the presence of extra virgin olive oil (EVOO), a healthy food with a high content of monounsaturated fatty acids,…
Antioxidant activity of cactus pear fruits and bioavailability of betalan components in healthy humans
2008
Consumption of fruit and vegetables is now associated with protection against various pathologies, including cancer and cardiovascular and cerebrovascular diseases, in which oxidative damage is an important etiologic factor. Various compounds from plant food, acting independently of known nutrients and micronutrients, have appeared very important in protecting human health. Most of these components can act as antioxidants or affect redox-dependent cell activities involved both in physiological and pathological events. In this scenery fruits of cactus pear (Opuntia ficus-indica), and the characteristic betalain pigments have recently attracted the attention of researchers. While suggesting m…
