Chemistry and Biological Activities of Flavonoids: An Overview
There has been increasing interest in the research on flavonoids from plant sources because of their versatile health benefits reported in various epidemiological studies. Since flavonoids are directly associated with human dietary ingredients and health, there is need to evaluate structure and function relationship. The bioavailability, metabolism, and biological activity of flavonoids depend ...
متن کاملSulphated Flavonoids: Biosynthesis, Structures, and Biological Activities.
The great diversity of enzymatic reactions in plant secondary metabolism allows the continuous discovery of new natural compounds and derivatives. Flavonoids, for example, can be found as aglycone or as several sorts of glycosylated, acetylated, methylated, and sulphated derivatives. This review focuses on sulphated flavonoids, an uncommon group of flavonoid derivatives found in some plant fami...
متن کاملIsolation of flavonoids and biological activities of Crotalaria Grahamiana
The flavonoids of Crotalaria grahamiana (family Popilionaceae) were isolated from the alcoholic extract by partition with benzene, diethyl ether, ethyl acetate respectively. On the basis of chemical and spectral analysis their structures are elucidated as 4’hydroxy flavone-7-O-rhamnoside and its aglycone.Identification of unknown compounds were established through comparison of chromatographic ...
متن کاملThe antitumor activities of flavonoids.
The flavonoids are polyphenolic compounds found as integral components of the human diet. They are universally present as constituents of flowering plants, particularly of food plants. The flavonoids are phenyl substituted chromones (benzopyran derivatives) consisting of a 15-carbon basic skeleton (C6-C3-C6), composed of a chroman (C6-C3) nucleus (the benzo ring A and the heterocyclic ring C), ...
متن کاملFlavonoids as vasorelaxant agents: synthesis, biological evaluation and quantitative structure activities relationship (QSAR) studies.
A series of 2-(2-diethylamino)-ethoxychalcone and 6-prenyl(or its isomers)-flavanones 10a,b and 11a-g were synthesized and evaluated for their vasorelaxant activities against rat aorta rings pretreated with 1 μM phenylephrine (PE). Several compounds showed potent vasorelaxant activities. Compound 10a (EC(50) = 7.6 μM, E(max) = 93.1%), the most potent one, would be a promising structural templat...
