Effects on the quality and nutritional traits of wood strawberry fruits in Sicily.

2011

In Sicily, the common woodland strawberry (Fragaria vesca) is spontaneous in the Madonie Mountains (554 m a.s.l.), Nebrodi Mountains (850 m) and Mount Etna (900 m). In this region, the main clone cultivated is ‘Fragolina di Sciacca e Ribera’, named after the towns where the crop originally developed. It is a Junebearing genotype and it is characterized by very small fruits, globose-conical shape, deep red colour, very soft flesh, strong aroma and flavor. Also ever-bearing clones are cultivated in Sicily where they are cropped for many months. Solid soluble content, total titratable acidity, total antioxidant capacity, total polyphenols and anthocyanins content were quantified in berry sampl…

Physicochemical Characterization, Antioxidant Activity, and Phenolic Compounds of Hawthorn (Crataegus spp.) Fruits Species for Potential Use in Food …

2020

Hawthorn belongs to the Crataegus genus of the Rosaceae family and is an important medicinal plant. Due to its beneficial effects on the cardiovascular system and its antioxidant and antimicrobial activity hawthorn has recently become quite a popular herbal medicine in phytotherapy and food applications. In this study, physicochemical characterization (color parameters, pH, titratable acidity, total soluble solids, soluble carbohydrate, total carotenoid, total phenols, and flavonoid contents), antioxidant activity (by ferric-reducing antioxidant power, FRAP assay), and quantification of some individual phenolic compounds of fruits of 15 samples of different hawthorn species (Crataegus spp.)…

Phytochemical Profile and Antioxidant, Antiproliferative, and Antimicrobial Properties of Rubus idaeus Seed Powder

2022

In the context of the contemporary research on sustainable development and circular economy, the quest for effective strategies aimed at revaluation of waste and by-products generated in industrial and agricultural production becomes important. In this work, an ethanolic extract from red raspberry (Rubus idaeus) seed waste (WRSP) was evaluated for its phytochemical composition and functional properties in term of antioxidative, antiproliferative, and antimicrobial activities. Chemical composition of the extract was determined by both HPLC-ESI-MS/MS and spectrophotometric methods. Phytochemical analysis revealed that flavan-3-ols and flavonols were the major phenolic compounds contained in W…

The intestinal 3M (microbiota, metabolism, metabolome) zeitgeist – from fundamentals to future challenges

2021

The role of the intestine in human health and disease has historically been neglected and was mostly attributed to digestive and absorptive functions. In the past two decades, however, discoveries related to human nutrition and intestinal host-microbe reciprocal interaction have established the essential role of intestinal health in the pathogenesis of chronic diseases and the overall wellbeing. That transfer of gut microbiota could be a means of disease phenotype transfer has revolutionized our understanding of chronic disease pathogenesis. This narrative review highlights the major concepts related to intestinal microbiota, metabolism, and metabolome (3M) that have facilitated our fundame…

Cytotoxic Potencial Acetogenins ofAnnonaGenus

2016

Over the centuries, nature has contributed to the basic needs of human beings. In particular, plants have cooperated as a source of drugs for the treatment of a broad spectrum of diseases because of the structural diversity of secondary metabolites. With strict attention to antineoplastic therapy, the search for anticancer drugs has increased in order to meet more specific and selective treatments. The acetogenins (ACGs), a class of secondary metabolites found exclusively in the family Annonaceae, are substances of great importance due to their well-known cytotoxic potency in human tumor cell lines in vitro , which can be exploited in designing anticancer agents. Among the 150 genera of Ann…

Indicaxanthin exerts anti-inflammatory effects on carrageenin-induced rat pleurisy.

Evaluation of antitumor and immunomodulatory properties of Indicaxanthin from Opuntia Ficus Indica (L. Mill) fruit

2020

Cancer is a growing health problem around the world and according to estimates from the International Agency for Research on Cancer (IARC), 14.1 million new cancer cases and 8.2 million cancer deaths worldwide have been reported in 2012 (Ferlay et al., 2015). By 2030, the global burden is expected to grow to 21.7 million new cancer cases and 13 million cancer deaths simply due to the growth and aging of the population. Indicaxanthin ((2S)-2,3-dihydro-4-[2-[(2S)-2a-carboxypyrrolidin-1- yl]ethenyl]pyridine-2a,6-dicarboxylic acid), a betalain pigment from cactus pear fruit, has been the object of sound experimental work over the latest years. As many phytochemicals, indicaxanthin is a redox-ac…

Cytotoxicity of botanicals and isolated phytochemicals from Araliopsis soyauxii Engl. (Rutaceae) towards a panel of human cancer cells.

2020

Abstract Ethnopharmacological relevance Araliopsis soyauxii Engl. (Rutaceae) is a Cameroonian medicinal plant traditionally used to treat lung diseases, malaria, and gonorrhea. It has been demonstrated that infectious disease contribute to about 20% of all human tumours. Aims of the study (1) To perform a phytochemical investigation of the dichloromethane-methanol 1:1 extracts of the bark (ASB), roots (ASR), and leaves (ASL) from Araliopsis soyauxii; (2) to evaluate the cytotoxicity of extracts and isolated compounds; (3) to determine the mode of induction of apoptosis of ASB and kihadanin B (12). Materials and methods Fourteen constituents of the crude extracts were isolated by column chro…

Pro-oxidant activity of indicaxanthin from Opuntia ficus indica modulates arachidonate metabolism and prostaglandin synthesis through lipid peroxide …

2014

Macrophages come across active prostaglandin (PG) metabolism during inflammation, shunting early production of pro-inflammatory towards anti-inflammatory mediators terminating the process. This work for the first time provides evidence that a phytochemical may modulate the arachidonate (AA) metabolism in lipopolysaccharide (LPS)-stimulated RAW 264.7 macrophages, promoting the ultimate formation of anti-inflammatory cyclopentenone 15deoxy-PGJ2. Added 1 h before LPS, indicaxanthin from Opuntia Ficus Indica prevented activation of nuclear factor-κB (NF-κB) and over-expression of PGE2 synthase-1 (mPGES-1), but up-regulated cyclo-oxygenase-2 (COX-2) and PGD2 synthase (H-PGDS), with final product…
