摘要：

Quercetrin, quercetin and chlorogenic acid were measured in urine or in drugs by combination of boronic acid affinity chromatography and HPLC. Simple reversed-phase HPLC with UV detection was used to determine quercetrin in five different Solidago virgaurea drugs. For determination of quercetrin in human urine immobilized boronic acid was applied for sample pretreatment. This procedure leads to a determination limit of 0.01 mu g/ml with a recovery rate of 95.3%. The first results using this method for quercetrin pharmacokinetics are presented.
