title: Determined of bufuralol and its metabolites in plasma by mass fragmentography and by gas chromatography with electron capture detection.
abstract: A sensitive method for the simulataneous determination of bufuralol and its pharmacologically active metabolites in huamn plasma is described. The O-timethylsilyl,N-trifluoroacetyl derivatives are assayed by mass fragmentography. Sensitivity is 1 ng 76(-1) plasma for bufaralol and about 250 pg ml(-1) for the metabolites. An alternative procedure which uses gas chromatography with electron capture detection is also described. The sensitivity of this is about 10 ng ml(-1) plasma for all drug-related components.
