Luteolin antioxidant activity

The aqueous and ethyl acetate flower extracts rich in luteolin and luteolin-7-gluco-side exhibited antioxidant activity in the 2,2-iphenyl-l-picrylhydrazyl (DPPH) free radical scavenging assay as well as in the phosphatidylcholine liposome assay. Lower concentrations, however, had a pro-oxidant effect. [Pg.239]

Flower extracts possess strong in vitro antioxidant activity resembling that of superoxide dismutase (SOD) with luteolin and azaleatin glycosides possessing the highest activity. ... [Pg.315]

An extract from Lactuca indica showed significant free radical scavenging activity, and protected phixl74 supercoiled DNA against strand cleavage and reduced oxidative stress in human promyelocytic leukemia HL-60 cells. On account of protocatechulic acid, methyl p-hydroxybenzoate, caffeic acid, 3,5-dicaffeoylquinic acid, luteolin 7-O-fT glucopyranoside, and quercetin 3-0-(3-g 1 ucopyranoside are the major antioxidative constituents (111). [Pg.221]

Figure 5.2 Structures of luteolin (L), kaempferol (K), and taxifolin (T). A comparison of the antioxidant (inhibition of MPO and radical scavenging activity) and anti-inflammatory (inhibition of LTB4) activity with that of quercetin (Q) is summarized.
