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
## Abstract A sensitive GCโECD assay has been developed for the simultaneous determination of midazolam (I) and its ฮฑโhydroxy metabolite (II) in plasma. The assay involves extraction of both compounds into ether at alkaline pH (pH 12), followed by silylation of the ฮฑโhydroxy metabolite with N,Oโbis
