## Abstract In this paper, a method was described to determine cocaine (COC) and benzoylecgonine (BZE) in human urine samples by GC‐MS detection. The extraction of analytes from urine samples was achieved in an Oasis hydrophilic–lipophilic balance column (20 mm×3.9 mm id, dp=25 μm; Waters, USA), in

Butorphanol is an opioid used as analgesic in humans and other species. In horses, it can cause locomotor stimulation at low doses. This drug is not well chromatographed by GC and so, it is necessary to transform it into a more suitable compound, which can be done by derivatization. The derivatizati

A new method for the analysis of tetrahydroisoquinolines (TIQ) from biological materials is described. The method combines extraction and acylation of the TIQs from urine in a one-step procedure followed by analysis by gas chromatography/mass spectrometry. By this extractive derivatization method, a
