Stereoselective liquid chromatographic determination of 1'-oxobufuralol and 1'-hydroxybufuralol in rat liver microsomal fraction using hollow-fiber liquid-phase microextraction for sample preparation.


A three-phase hollow-fiber liquid-phase microextraction (HF-LPME) method for the stereoselective determination of bufuralol metabolites 1'-oxobufuralol (1'-Oxo-BF) and 1'-hydroxybufuralol (1'-OH-BF) in microsomal preparations is described for the first time. The HPLC analysis was carried out using a Chiralcel OD-H column with hexane/2-propanol/methanol (97… (More)
