title: Thin-layer chromatographic analysis of some beta-blocking drugs in plasma.
abstract: beta-receptor blockers--atenolol, celiprolol, metoprolol, propafenone, propranolol and talinolol--extracted from plasma, were separated by TLC method on silica gel by ascending technique. Isolation of drugs was performed by using liquid-liquid extraction after alkalization of blood plasma. Suitable conditions for separation were established using ethyl acetate-acetone-ammonia (5:4:1) as the mobile phase. The substances were identified by UV irradiation (254 nm) or by reactions with a variety of reagents. The visual limits of determination of named beta-blockers, after reaction with indicators, are between 100-300 ng; celiprolol and talinolol are the most sensitively detectable of investigated substances.
