It is quite clear that in vitro, carotenoids can inhibit the propagation of radical‐initiated lipid peroxidation, and thus fulfill the definition of antioxidants.

Apocarotenals of Phenolic Carotenoids for Superior Antioxidant Activities

A series of para-phenolic carotenes 1 with ortho- and meta-substitutions were respectively prepared utilizing the benzenesulfonyl protection method, which demonstrated the importance of the ring

Health impact of marine carotenoids

Major nutritional effects of astaxanthin, such as cardio-, skin-, and ocular-protective effects, are based on its in vivo antioxidant activity, however, the antioxidant activity of fucoxanthin is not largely involved in its characteristic nutritional activity and anti-obesity andanti-diabetic effects.

Contribution of Major Hydrophilic and Lipophilic Antioxidants from Papaya Fruit to Total Antioxidant Capacity

Several studies have shown that phenolic and carotenoid compounds protect against oxidative stress, reducing the risk of cardiovascular diseases and some types of cancers. The objective of this

The carotenoids as anti-oxidants--a review.

Cinnamates and hydroxybenzoates in the diet: antioxidant activity assessed using the ABTS•+ radical cation

Examines the antioxidant activities of a range of hydroxy‐substituted phenolic acids by estimating their relative abilities to scavenge the ABTS_+ radical cation generated in the aqueous phase,

A density functional theory study for the role of end groups on the antioxidative potency of carotenoids

Role of carotenoid end groups on their chain-breaking potency against lipid peroxidation was explored using density functional theory. Hydrogen abstraction and addition of the peroxide and O2 of the

Acetamide Derivatives with Antioxidant Activity and Potential Anti-Inflammatory Activity

The synthesis and antioxidant activity of some new acetamide derivatives were reported and their structures were elucidated by NMR analysis and their melting points were measured.



The relative antioxidant activities of plant-derived polyphenolic flavonoids.

The relative antioxidant activities, against radicals generated in the aqueous phase, of a range of plant-derived polyphenolic flavonoids, constituents of fruit, vegetables, tea and wine, have been assessed and compounds such as quercetin and cyanidin have antioxidant potentials four times that of Trolox, the vitamin E analogue.

Antioxidant defense systems: the role of carotenoids, tocopherols, and thiols.

The ability of the lipid-soluble carotenoids to quench singlet molecular oxygen may explain some anticancer properties of the carOTenoids, independent of their provitamin A activity.

Scavenging of Nitrogen Dioxide, Thiyl, and Sulfonyl Free Radicals by the Nutritional Antioxidant -Carotene (*)

Mechanisms of free radical scavenging by the nutritional antioxidant β-carotene have been investigated by pulse radiolysis and rate constants for thiyl radical-addition reactions vary from 106 to 109M s and correlate with the lipophilicity of the thiyle radical under study.

Carotene-oxygen radical interactions.

All-trans beta-carotene radical anion efficiently transfers an electron to oxygen but the reverse reaction is not observed and, instead, the formation of a beta- carotene-superoxide radical addition complex is suggested which may be related to the anti-cancer properties of these molecules.
