Quercetin 3-acetyl-7,3',4'-trisulphate (ATS) and quercetin 3,7,3',4'-tetrasulphate (QTS) obtained from Flaveria bidentis (Asteraceae) were investigated in vitro for anticoagulant activity. Three different concentrations of each flavonoid were assayed at different incubation times, showing at 1 mM
Sulphated esters of the flavonoids sulphated quercetin 3,7,3',4'-tetrasulphated (QTS) and quercetin 3-acetyl-7,3,4'-trisulphate (ATS), isolated from Flaveria bidentis, have demonstrated anticoagulant and antiplatelet properties. In this study, we examined if both compounds affected the expression of
Flaveria bidentis is a plant species that has as major constituents sulphated flavonoids in the highest degree of sulphatation. Among them, quercetin 3,7,3',4'-tetrasulphate (QTS) and quercetin 3-acetyl-7,3',4'-trisulphate (ATS) are the most important constituents. Both showed anticoagulant
