Six new compounds, comprising three flavonoid glycosides and their respective coumaroyl esters, have been isolated and characterized from the methanol extract of the leaves of Campylospermum calanthum, along with three known flavonoid aglycones, 7-O-methyl apigenin (1), 7-O-methyl luteolin (2), and 7-O-methyl quercetin (3). Their structures were elucidated based on chemical evidence as well as ...
متن کاملSynthesis of Neohesperidin Glycosides and transferase from an Alkalophilic
Citrus fruits contain two groups of flavonoid glycosides that have either rutinose (L-rhamnopyranosyl-ct-1,6-glucopyranoside) or neohesperidose (L-rhamnopyranosyl-:-1.2glucopyranosiele) as their saccharide components. Flavonoid rutinosides such as hesperidin. from mandarin oranges, are tasteless, and on the other hand, flavonoid neohesperidosides such as neohesperidin and naringin, from grapefr...
