1. A gas chromatographic-mass fragmentographic method has been developed to determine piribedil and its metabolite S-584, using diazepam as internal standard. The metabolite was derivatized as a trimethylsilyl ether for gas chromatographic analysis. The minimum detectable amount of piribedil and the metabolite was 10 ng/g tissue. 2. Levels of piribedil and its metabolite in the striatum were determined by mass fragmentography.
