摘要:Dipterex in blood was determined by gas-liquid chromatography with a flame photometric detector on 2.0-m glass column packed with 25% carbowax 20 M at 180°. Determination was carried out successfuly by using trimethyl phosphate as an internal standard. Dipterex was extracted from blood with ether after salting-out with magnesium sulfate and adjusting to pH 5.8. The clean-up procedure suitable for the extract was carried out by a column packed with silica gel containing 15% water by weight. The component was eluted with acetone : methanol (90 : 10) mixture. The recovery of Dipterex added to blood was 94.3%.
