[HPLC determination of troxerutin in plasma and urine following oral administration in man].
A high-performance liquid chromatographic method (HPLC) is described for the analysis of 3',4',7-tri-O-(beta-hydroxy-ethyl)-rutoside (troxerutin) in human plasma and urine. After separation of interfering substances on XAD-2 trihydroxyethylrutoside is converted to tetrahydroxyethylrutoside by 2-chlorethanol in alkaline medium. After HPLC-separation tetrahydroxyethylrutoside is quantified by fluorescence detection. The pharmacokinetics of troxerutin were measured in plasma after oral administration to man. The relative bioavailability of the drug from Venelbin was 97.8 +/- 37.1% compared to an aqueous standard solution.
