Antimutagenic activity of flavonoids from Chrysanthemum morifolium.
A methanol extract from the flower heads of Chrysanthemum morifolium showed a suppressive effect on umu gene expression of the SOS response in Salmonella typhimurium TA1535/pSK1002 against the mutagen 2-(2-furyl)-3-(5-nitro-2-furyl)acrylamide (furylfuramide). The methanol extract was re-extracted with hexane, chloroform, ethyl acetate, butanol, and water. The ethyl acetate fraction showed a sup...
متن کاملStructure-radical scavenging activity relationships of flavonoids.
The objective of this work is to establish the structural requirements of flavonoids for appreciable radical-scavenging activity (RSA) and elucidate a comprehensive mechanism that can explain their activity. To this end, the RSA of 52 flavonoids against 2,2-diphenyl-1-picrylhydrazyl was determined. The relative change in energy (DeltaH(f)) associated with the formation of various flavonoidal an...
متن کاملElectrochemical Study of Flavonoids in Acetonitrile: Structure-Activity Relationships
Relations between structure, antioxidant capacity and formal redox potentials (E°’) of six flavonoids dissolved in acetonitrile were studied by cyclic voltammetry and square wave voltammetry using a glassy carbon electrode. This work shows correlation between the electrochemical parameter E°’ and the number of hydroxyl groups present in the B ring of flavonoids. Besides, it has been observed th...
متن کاملStructure-activity relationships of antioxidant activity in vitro about flavonoids isolated from Pyrethrum tatsienense
AIM Antioxidant activity is one of the important indexes for estimating medicinal value for the traditional Chinese medicine. The aim of this study is to investigate the antioxidant activity of 11 flavonoids mainly revealing luteolin as mother nucleus isolated from Pyrethrum tatsienense. MATERIALS AND METHODS The antioxidant activity of 11 flavonoids was measured in vitro using the classical ...
متن کاملStructure-radical scavenging activity relationships of hydroxytoluene derivatives
Research works proposed that radical scavenging activity of flavonoids is due to ring B, andthe remaining part of the molecule can be disregarded. Thus the objective of this work is toobserve whether hydroxytoluenes account the radical scavenging activity of flavonoid and toestablish structural requirements for their activity (as they showed appreciable activity) andelucidate a comprehensive me...
