background: although several studies have investigated the association between ovarian cancer risk and nonisoflavone flavonoids intake, these findings are inconsistent. this systematic review of published epidemiological studies was conducted to summarize and clarify the evidence on the association between ovarian cancer incidence and nonisoflavone flavonoids intake. materials and methods: pubm...

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...

eight salvia l. species including s. spinosa l., s. reuterana boiss., s. macrosiphon boiss., s. syriaca l., s. nemorosa l., s. virgata jacq., s. sharifii rech. f. & esfand. and s. mirzayanii rech. f. & esfand. were studied for flavonoid compounds. these constituents were analyzed using two-dimensional maps on silica gel 60f thin layer chromatography. the flavonoid compounds of each spec...

Recent studies have demonstrated the importance of flavonoid intake and disease risk, however the association between flavonoid intake and obesity has not been evaluated in a nationally representative sample of US adults. The objective of the study was to evaluate the association between flavonoid consumption and established risk factors for obesity and obesity-related inflammation. Data from a...

Flavonoid biosynthesis profile was clarified by fruit bagging and re-exposure treatments in the green Chinese pear 'Zaosu' (Pyrus bretschneideri Rehd.) and its red mutant 'Red Zaosu'. Two distinct biosynthesis patterns of flavonoid 3-glycosides were found in 'Zaosu' pear. By comparison with 'Red Zaosu', the biosynthesis of flavonoid 3-galactosides and flavonoid 3-arabinosides were inhibited by ...

stachys genus with medicinal properties and high polymorphic features has been considered oneof the largest genera of lamiaceae. the aim of this study was to determine the flavonoid patternvariations and flavonoid groups in ten stachys species belonging to two sections; fragilicaulis,and aucheriana. the studied species were collected from natural habitats in iran and analysedfor their flavonoid...

BACKGROUND Within- and between-person variation in nutrient intake is well established, but little is known about variability in dietary flavonoid intake, including the effect of seasonality. METHODS Within- and between-individual variability of flavonoid intake, and intake of flavonoid subclasses was examined in older adults (n = 79; mean age 70.1 y (range: 60y-80y)), using three separate 4-...

OBJECTIVE To estimate flavonoid intake in the Australian population. DESIGN Flavonoid consumption was estimated from 24-hour recall data and apparent consumption data using US Department of Agriculture flavonoid composition data. SUBJECTS The National Nutrition Survey 1995 assessed dietary intake (24-hour recall) in a representative sample (n=13,858) of the Australian population aged 2 year...

We examined whether flavonoids act as endogenous auxin transport regulators during gravity vector and light intensity changes in Arabidopsis thaliana roots. Flavonoid deficient transparent testa4 [tt4(2YY6)] seedlings had elevated root basipetal auxin transport compared with the wild type, consistent with the absence of a negative auxin transport regulator. The tt4(2YY6) roots had delayed gravi...
