Abstract
Reported here is a rapid, sensitive and relatively inexpensive procedure using gas chromatography with nitrogen–phosphorus detection (GC–NPD) to quantify buspirone levels in brains of rats. The analyte was directly extracted from brain homogenate with toluene after basification and then subjected to GC–NPD analysis using a capillary column. The calibration curves were linear over the range of 10 to 320 ng per 2 ml of brain homogenate, with typical r 2 values >0.99. The assay was highly reproducible and gave peaks with excellent chromatographic properties.
