Determination of butaperazine in biological fluids by gas chromatography using nitrogen specific detection system

Journal of Chromatographic Science
J I JavaidJ M Davis


A simple and sensitive gas chromatographic method for the quantitative determination of butaperazine in biological fluids is described. The use of a nitrogen specific detector reduces the number of interfering peaks, thereby increasing the number of samples that can be analyzed. When butaperazine is extracted from 2 ml of plasma, the coefficient of variation is 7.4% over the concentration range of 5-180 ng/ml. The method was used to measure the levels in plasma and red blood cells in schizophrenic patients treated with butaperazine. It was also extended to measure butaperazine levels in rat red blood cells, plasma, liver, and brain after intraperitoneal injection (15 mg/kg).

Coronaviruses encompass a large family of viruses that cause the common cold as well as more serious diseases, such as the ongoing outbreak of coronavirus disease 2019 (COVID-19; formally known as 2019-nCoV). Coronaviruses can spread from animals to humans; symptoms include fever, cough, shortness of breath, and breathing difficulties; in more severe cases, infection can lead to death. This feed covers recent research on COVID-19.
