Circular dichroism is specially suited to determine flavone glycosides in human serum at low concentrations.

,Hochdruckflüssigchromatographische Bestimmung von O-(,-Hydroxyethyl)-rutosiden in Humanserum,d on a XAD-2 microcolumn and the methanol eluate finally chromatographed on a reversed phase column, using a HPLC-system with UV detection. An almost linear calibration curve and about 80% recovery were obtained. The method has a detection limit of 1 mg/1 (UV 256 nm) and was successfully applied to pharmacokinetic studies in human volunteers.

Venoruton? can thus increase the speed of venous blood flow by reducing viscosity. The reasons can be seen in the changes in both the plasma and corpuscular components of the blood.
