The mis-identification of the major antioxidant flavonoids in young barley (Hordeum vulgare) leaves.
Several papers have appeared in the literature since 1992 which refer to a major "isoflavonoid" antioxidant in young green barley leaves (Hordeum vulgare) as 2''-O-glucosylisovitexin. In the present paper the original NMR data supporting this structural assignment are examined and found to have been misinterpreted. HPLC and NMR data are used to prove that the major flavonoid antioxidants in you...
متن کاملPolyphenols, flavonoids and antimicrobial properties of methanolic extract of fennel (Foeniculum vulgare Miller)
To address the ever increasing resistance of pathogens and need of safer preservatives for food products, herbs are being explored for antimicrobial properties. Methanolic extract of Fennel (Foeniculum vulgare Miller) was analyzed for the presence of polyphenolic compounds, flavonoids and antibacterial potential. The extract, rich in flavonoids (9.325 ± 1.25 mg QE/g dry seeds) was subjected to ...

Synthetic antioxidants commonly used in processed foods have side effects and are toxic. Therefore, there is a need for more effective, less toxic and cost effective ant...
متن کاملEchium vulgare L
Changes in the composition of fatty acids (FA) were determined in lipid extracts isolated from developing ovaries containing ovules and developing seeds of Echium vulgare L. The samples were collected successively over 20 days beginning with the first day after flowering. The contents of the n-6 FA family members, i.e., γ-linolenic (GLA) (C18 : 3) and linoleic (LA) (C18 : 2) acids changed in a ...

suns. The extension of the Andromeda nebula beyond the photographic limits is presumably typical of what may be found for other such objects. Comparisons with the surface brightness of the galaxy are still hampered by uncertainties in the data for our own system. There may be no part of the galaxy which, seen from outside, would be as bright as the central portion of M 31. In the latter system ...
