Abstract:
The purified compound, 4', 5, 6, 7-tetramethoxyflavone, is an active ingredient isolated from Eupatorium odoratum, a Thai indigenous plant that has long been used to stop bleeding. This compound was studied in vitro for the effect on blood clotting factor activities. It was found that the compound enhanced blood coagulation, the observed APTT being shorter than that observed in the control. The result suggested that the compound accelerated clotting time through the intrinsic pathway of the coagulation which may involve the reaction of factor XII, factor XI, factor IX or factor VIII.

In the visual method, metal-ion indicators (metallochromic dyes), which have distinct colors in their free and complex forms, are added to the mixture to signal the titration's end point. They form stable complexes with metal ions, but these complexes are weaker than the corresponding metal–EDTA complexes. As a result, EDTA...
