متن کاملKaempferol and kaempferol rhamnosides with depigmenting and anti-inflammatory properties.
The objective of this study was to examine the biological activity of kaempferol and its rhamnosides. We isolated kaempferol (1), a-rhamnoisorobin (2), afzelin (3), and kaempferitrin (4) as pure compounds by far-infrared (FIR) irradiation of kenaf (Hibiscus cannabinus L.) leaves. The depigmenting and anti-inflammatory activity of the compounds was evaluated by analyzing their structure-activity...
متن کاملHPLC quantification of kaempferol-3-O-gentiobioside in Cassia alata.
Kaempferol-3-O-gentiobioside, the major flavonoid glycoside in Indonesian Cassia alata was quantified in various parts of the plant. The mature leaf was found to contain the highest content of this metabolite. A decrease of the flavonoid content in the juvenile leaf during the period of October through December was also observed. The contents ranged from 2.0 to 5.0% and 1.0 to 4.0% in mature an...
متن کاملSelective methylation of kaempferol via benzylation and deacetylation of kaempferol acetates
A strategy for selective mono-, di- and tri-O-methylation of kaempferol, predominantly on the basis of selective benzylation and controllable deacetylation of kaempferol acetates, was developed. From the selective deacetylation and benzylation of kaempferol tetraacetate (1), 3,4',5,-tri-O-acetylkaempferol (2) and 7-O-benzyl-3,4'5,-tri-O-acetylkaempferol (8) were obtained, respectively. By contr...
