Polyphenols of fruits and vegetables form an important part of human dietary compounds. Relatively little is known about accumulation of phenolics during fruits ripening process. The goal of this work was to study the changes in antioxidant activity and in content of 30 polyphenols during ripening of tomato fruits. Five organically and conventionally grown tomato cultivars were investigated at ...

Edible cassava leaves (Manihot esculenta) were consumed as vegetables for their bioactive compounds, however the effect of harvesting time on these compounds and antidiabetic anti-obesity inhibitory activities scarcely reported in literature. Phenolics from edible harvested at different times assessed using HPLC-DAD, investigated before after vitro gastrointestinal digestion. The results showed...

The health-promoting effects of phenolic compounds depend on their bioaccessibility from the food matrix and their consequent bioavailability. We carried out a randomized crossover pilot clinical trial to evaluate the matrix effect (raw flesh and juice) of 'Ataulfo' mango on the bioavailability of its phenolic compounds. Twelve healthy male subjects consumed a dose of mango flesh or juice. Bloo...

Antitrypanosomal natural products with different structural motifs previously shown to have growth inhibitory activity against Trypanosoma brucei were docked into validated drug targets of the parasite, which include trypanothione reductase, rhodesain, farnesyl diphosphate synthase, and triosephosphate isomerase. The in-silico calculations predicted that lowest energy docked poses of a number o...

The effects of superatmospheric oxygen levels on anthocyanins, phenolics, antioxidant activity and fruit quality of blueberries (Vaccinium corymbosum L.) and strawberries (Fragaria × ananassa Duch.) during storage at 5°C were investigated. High oxygen treatment increased the levels of total anthocyanins, total phenolics as well as several individual flavonoid compounds during the first 21 days ...

* Studies of ultraviolet (UV) light-induced DNA damage in three Antarctic moss species have shown Ceratodon purpureus to be the most UV tolerant, despite containing lower concentrations of methanol-soluble UV-screening compounds than the co-occurring Bryum pseudotriquetrum. * In this study, alkali extraction of cell wall-bound phenolics, combined with methanol extraction of soluble phenolics, w...

Propolis is a natural resin of a variety of plant origins collected by honeybees to seal gaps and cracks in their hives. Propolis was used as a remedy of various diseases due to its versatile biological activities. At least 200 compounds have been identified in the world. The present study aimed to investigate the chemical composition of two samples of Sudanese propolis collected from El-Faki H...

the effect of postharvest uv-c irradiation on phenolic compounds accumulation was investigated in berries of ‘rishbaba’ table grape (vitis vinifera cv. rishbaba). grape clusters were harvested at mature stage and irradiated with uv-c using fluorescent germicidal lamp (30 w, 90 cm) with a peak emission at 254 nm for 0 (control), 5 and 10 min. uv-c treatment had significant effect on individual p...

This review examines the discovery of naturally occurring phytochemicals antagonistic toward plant-parasitic and other nematodes. Higher plants have yielded a broad spectrum of active compounds, including polythienyls, isothiocyanates, glucosinolates, cyanogenic glycosides, polyacetylenes, alkaloids, lipids, terpenoids, sesquiterpenoids, diterpenoids, quassinoids, steroids, triterpenoids, simpl...
