Endosufan, a and b, and three conversion products, sulphate, ether and lactone, were simultaneously determined in human serum by means of an analytical procedure which combines extraction with organic solvents, clean-up with H 2 SO 4 and by liquid column chromatography, and detection by gas chromato

β¦ Synopsis
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.
