abstract: The quantitative analysis of propranolol and its metabolite N-desisopropylpropranolol in plasma and urine is described. The drugs are extracted into 2-pentanol-heptane, and the solvent is concentrated. The whole residue is chromatographed on silica gel plates. The compounds are determined directly on the thin-layer plates without derivatization. The recovery of propranolol from plasma is 70%, with a standard deviation of +/- 4%.
