title: A gas chromatography-mass fragmentographic method for the assay of ajmaline and its monochloroacetyl ester.
abstract: A gas chromatograph-mass fragmentography method for simultaneous assay of 17-monochloroacetyl-ajmaline (MCAA) and its hydrolysis product, ajmaline, is described. Recovery of both compounds from whole blood averaged 71%. About 5% of MCAA was hydrolyzed during the assay procedure. The method was accurate and precise to within a few percent. It was suitable for assays of blood levels in the dog after an i.v. dose of 2 mg/kg or an oral dose of 5 mg/kg.
