P11: The Effect of Flavonoids in Memory
Flavonoids may exert particularly powerful actions on mammalian cognition and may reverse age-related declines in memory and learning. Flavonoids can be modulated neuronal function and there by influencing memory, learning and cognitive function. Dietary supplementation with flavonoid-rich foods, such as blueberry, green tea and Ginkgo biloba lead to significant reversals of age-related deficit...
متن کاملSterols and Flavonoids of Lomatopodium staurophyllum
Background: The genus Lomatopodium Fisch. & C.A.Mey., belongs to Apiaceae family and contains one herbaceous species growing wildly in Iran. There are only a few papers about the chemical constituents of these plants. Here, we focused on the isolation and identification of the main flavonoid glycosides and sterols from the aerial parts of L. staurophyllum, which has not been previously reported...
متن کاملEnteric disposition and recycling of flavonoids and ginkgo flavonoids.
OBJECTIVE The objective of this study was to determine the intestinal and microbial disposition of flavonoids and how these disposition processes affect their enteric recycling. DESIGN Studies were performed using a perfused rat intestinal model or using enrichment cultures and a pure isolate of Enterococcus avium (LY1). RESULTS In the rat intestine, aglycones, such as quercetin and apigeni...
متن کاملNovel antioxidant compounds from tart cherries (Prunus cerasus).
As indicated by an Fe(II)-induced liposome peroxidation bioassay, the EtOAc extract of tart cherries (Prunus cerasus) was found to have strong antioxidant activity. Purification of this extract afforded chlorogenic acid methyl ester (1) and three novel compounds, 2-hydroxy-3-(o-hydroxyphenyl) propanoic acid (2); 1-(3', 4'-dihydroxycinnamoyl)-cyclopenta-2,5-diol (3), and 1-(3', 4'-dihydroxycinna...
متن کاملFlavonoids of Crotalaria sessiliflora.
Phytochemical investigation of the whole plants of Crotalaria sessiliflora L. led to the isolation of four flavonoids. The structures of these compounds were identified as 2',4',5,7-tetrahydroxyisoflavone (1), 2',4',7-trihydroxyisoflavone (2), 4',7-dihydroxyflavone (3), and isovitexin (4) using spectroscopic analysis. Among these, compounds 2, and 3 have not been reported from Crotalaria specie...
