摘要:

A simple, precise and rapid high performance thin layer chromatographic method is developed using chloroform: methanol (9:1) as mobile phase for simultaneous determination of Theophylline and Etofylline in pharmaceutical dosages. Paracetamol was used as an internal standard. The method is linear in the concentration range of 20 – 80 ng for Theophylline and 60–240 ng for Etofylline.
