Influence of anti-inflammatory flavonoids on degranulation and arachidonic acid release in rat neutrophils.[Pubmed:8018254]
Z Naturforsch C. 1994 Mar-Apr;49(3-4):235-40.
We assessed the effects of 24 flavonoid derivatives, reported as anti-inflammatory, on lysosomal enzyme secretion and arachidonic acid release in rat neutrophils. Amentoflavone, Quercetagetin-7-O-glucoside, apigenin, fisetin, kaempferol, luteolin and quercetin were the most potent inhibitors of beta-glucuronidase and lysozyme release. The first compound was also able to inhibit basal release. These flavonoids besides chrysin and to a reduced extent, naringenin, significantly inhibited arachidonic acid release from membranes. A correlation between degranulation and arachidonic acid release was found for this series of compounds. Structure-activity relationships and implications for the anti-inflammatory effects of these flavonoids were discussed.
Anthocyanins and other flavonoids as flower pigments from eleven Centaurea species.[Pubmed:25924526]
Nat Prod Commun. 2015 Mar;10(3):447-50.
Anthocyanins and other flavonoids were isolated from the flowers of eleven Centaurea species, C. macrocephala, C. rupestotilis and C. suaveolens, which produce yellow flowers, and C. achtarovii, C. dealbata, C. montana, C. nigra, C. scabiosa, C. simplicicaulis, C. hypoleuca and C. triumfetti, which have cyanic flowers. Four anthocyanins, cyanidin 3,5-di-O-glucoside, cyanidin 3-O-(6"-malonylglucoside)-5-O-glucoside, cyanidin 3-O-(6"-succinylglucoside)-5- O-glucoside and cyanidin glycoside, were detected in the cyanic flowers of seven Centaurea species. Of these anthocyanins, the first two were found as major anthocyanins. In the cyanic species, four other flavonoids, apigenin 7-O-glucuronide-4'-O-glucoside, malonylated apigenin 7,4'-di-O-glucoside, apigenin 7-0- glucuronide and kaempferol glycoside, were also isolated. On the other hand, nine flavonols and four flavones were isolated from the three yellow-flowered species, and identified as quercetagetin, quercetagetin 7-O-glucoside, quercetagetin 3'-methyl ether 7-O-glucoside, patuletin, patuletin 7-O-glucoside, quercetin 7-O-glucoside, kaempferol 3-methyl ether, kaempferol 3-methyl ether 4'-O-glucuronide and isorhamnetin 3-O-galactoside, and apigenin, apigenin 7- O-glucuronide, luteolin 7-O-glucoside and apigenin 6,8-di-C-glucoside (vicenin-2). Of these flavonoids, the former five flavonols are "yellow flavonols", and it was shown that their flower colors are due to these compounds.
