Air pollution adversely affects skin,leading to skin inflammation and premature skin *** derived antioxidant compounds have been considered to be promising in discovery of effective agents for the protection of skin from the damage by air *** previous studies demonstrated that Averrhoa carambola fruit(known as star fruit)is rich in flavonoid C-glycosides with unique structures and potent antioxidant ***,the star fruit extract(SFE)and main flavonoid C-glycoside components,carambolasides I,J,and p(1-3),carambolaflavone B(4),and isovitexin 2″-O-α-l-rhamnoside(5),were investigated for the activity against air pollutant stress in human *** a result,SFE and compounds 1-5 exhibited significant inhibitory activity against protein carbonylation in oxidative-stressed stratum corneum with the best activity being shown by compound *** and compounds 2-5 were also active against engine exhaust-induced protein carbonylation in stratum *** further evaluated,SFE and com-pound 3 significantly inhibited gene expression of the key inflammation mediators IL-1αand COX-2 in pM-stressed *** results indicated that SFE and the flavonoid C-glycosides are potentially effective against air pollutant-induced skin inflammation and premature aging.
