Isolation of flavonoids and a chalcone from Helichrysum odoratissimum and synthesis of helichrysetin.

J. Nat. Prod. 52(3) , 629-33, (1989)

3,5-Dihydroxy-6,7,8-trimethoxyflavone, 3-O-methylquercetin, and helichrysetin were isolated from the flowers of the Rwandese medicinal plant, Helichrysum odoratissimum. Because of inconsistencies of the mp of the latter chalcone, a synthesis of helichrysetin ...

Neuroprotective effects of antioxidative flavonoids, quercetin, (+)-dihydroquercetin and quercetin 3-methyl ether, isolated from Opuntia ficus-indica var. saboten.

Brain Res. 965(1-2) , 130-6, (2003)

The flavonoids quercetin, (+)-dihydroquercetin, and quercetin 3-methyl ether were isolated from the ethyl acetate fractions of the fruits and stems of Opuntia ficus-indica var. saboten. In the present study, we evaluated their protective effects against oxida...

Quercetin-3-methyl ether suppresses proliferation of mouse epidermal JB6 P+ cells by targeting ERKs.

Carcinogenesis 33(2) , 459-65, (2012)

Chemoprevention has been acknowledged as an important and practical strategy for the management of skin cancer. Quercetin-3-methyl ether, a naturally occurring compound present in various plants, has potent anticancer-promoting activity. We identified this co...

Role of quercetin and its in vivo metabolites in protecting H9c2 cells against oxidative stress.

Biochimie 89(1) , 73-82, (2007)

The aim of this study was to investigate the potential of quercetin and two of its "in vivo" metabolites, 3'-O-methyl quercetin and 4'-O-methyl quercetin, to protect H9c2 cardiomyoblasts against H(2)O(2)-induced oxidative stress. As limited data are available...

Antioxidant activity and metabolite profile of quercetin in vitamin-E-depleted rats.

J. Nutr. Biochem. 19(7) , 467-74, (2008)

Dietary antioxidants interact in a dynamic fashion, including recycling and sparing one another, to decrease oxidative stress. Limited information is available regarding the interrelationships in vivo between quercetin and vitamin E. We investigated the antio...
