Effects of flavonoids on plasma coagulation tested in vitro by "screening tests"

The effects of four flavonoids: rutin, quercetin, morin and hesperidin on plasma coagulation has been examined by measuring aPTT, TT and PT. It is found that water solution of these flavonoids shows no effects in the measured quantities. This is due to their low solubility in water, and therefore, their low concentrations. Ethanolic solutions of these studied flavonoids, however, show significant prolongation of all measured coagulation times, but compared to ethanol alone, their anticoagulant effects are smaller. It is suggested that the observed effects can be attributed to the interaction of flavonoids with human plasma proteins.
