Food Content, Processing, Absorption and Metabolism of Onion Flavonoids

Critical Reviews in Food Science and Nutrition, 2007
The question as to how far the development of chronic diseases in humans depends on diet still remains open. Simultaneously, epidemiological studies suggest the consumption of a flavonoids rich diet might decrease the risk of degenerative changes and certain diseases.

In situ optical properties of foliar flavonoids: Implication for non-destructive estimation of flavonoid content

Journal of Plant Physiology, 2017
Flavonoids are a ubiquitous multifunctional group of phenolics of paramount importance for the terrestrial plants involved in protection from biotic and abiotic stresses, color and chemical signaling and other functions. Deciphering of in situ absorption of foliar Flv is important but was thought to be impossible due to a strong overlap with other ...

Flavonoid content of Asphodelus ramosus (Liliaceae)

Canadian Journal of Botany, 1997
In the course of a preliminary chemosystematic study of Asphodelus species, six flavonoids were first isolated and identified from A. ramosus subsp. ramosus var. ramosus. Only flavone structures were found. Two of them are rare C-glycoside structures and were observed only in the samples from one of the two geographic areas.

Flavonoid and cyanogenic contents of chaya (spinach tree)

Plant Foods for Human Nutrition, 2003
Chaya (Cnidoscolus chayamansa, McVaugh) is an ubiquitous plant in southern Mexico. Its high nutritional value is well documented but its content of toxic cyanide glycosides and medicinal metabolites are undetermined. The concentrations of HCN and derivatives from chaya leaves were measured in the range of 2.37-4.25 mg/100 of dry weight. Several thermal

Flavonoid content and antioxidant activity of Artemisia vulgaris L. “hairy” roots

Preparative Biochemistry & Biotechnology, 2019
We investigated the effect of Agrobacterium rhizogenes-mediated transformation on antioxidant activity of Artemisia vulgaris “hairy” roots. It appeared that transformation may increase flavonoid content as well as DPPH-scavenging activity and ability to ...

Consumer attitudes towards enhanced flavonoid content in fruit

Food Research International, 2009
Flavonoids from fruit and vegetables are currently widely studied as components that have the potential to provide multiple health benefits. In this study consumer perceptions of flavonoids were examined. The data (N = 130) were collected in focus group discussions in Finland, The Netherlands and France. In general, the term ‘flavonoid’ was unfamiliar.

Flavonoid contents and antioxidant activities from Cinnamomum species

Innovative Food Science & Emerging Technologies, 2009
Abstract Cinnamomum has long been regarded as a food or medicinal plant. Leaves of five species of Cinnamomum, namely C. burmanni, C. cassia, C. pauciflorum, C. tamala and C. zeylanica, were chosen to investigate their antioxidant activities in this study. C. zeylanica exhibited the highest total phenolic content while C.
