The effects of genetic, pre-harvest (season of harvest, spear diameter, spear portion and spear tip color) and post-harvest factors (storage and domestic preparation practices, e.g., peeling and cooking) on total phenolic, flavonoid and ascorbic acid content of white asparagus spears and their correlation with antioxidant capacity (DPPH and FRAP) were studied. Results showed that genetic materi...

BACKGROUND Studies have suggested the chemopreventive effects of flavonoids on carcinogenesis. Yet numbers of epidemiologic studies assessing dietary flavonoids and breast cancer risk have yielded inconsistent results. The association between flavonoids, flavonoid subclasses (flavonols, flavan-3-ols, etc.) and the risk of breast cancer lacks systematic analysis. OBJECTIVE We aimed to examine ...

Honey is a natural food produced by bees from the nectar of flowers and is a mixture of carbohydrates, amino acids, enzymes, vitamins and many bioactive compounds. Due to its special composition, honey is a functional food with antibacterial, anti-inflammatory and antioxidant properties. Studies have shown that honey’s properties depend mainly on the vegetable source from which it is obtained, ...

background and aims: flavonoids as polyphenolic naturally occurring compounds have antioxidant activity. there is increasing evidence suggests that flavonoids may affect the activity of enzymes. paraoxonase 1 is calcium - dependent enzyme that is present in high density lipoproteins. this enzyme has an important role in the prevention of low density lipoprotein oxidation. we investigated the ef...

Plants with hypoglycemic properties are important in the treatment of diabetes. One of the mechanisms in reducing blood glucose is preventing the digestive absorption of glucose. The aim of this study was to evaluate the antioxidant properties of some traditional medicinal plants collected from different regions of Iran and their effects on glucose diffusion decrease. The amounts of phenolic co...
