[Interference of minovine (a Vinca minor alkaloid) on hospital emergency toxicologic tests for derivatives of 5H-dibenzo(b,f)azepine].

The authors report the possible interference due to minovine when seeking tricyclic antidepressant derivatives in biological material or pharmaceutical substances. However, their work has shown that kinetic studies using absorption spectrophotometry of the colouration obtained with phosphoric-ceric reagent and thin layer adsorbant chromatography make it possible to eliminate the doubt and identify the Vinca-Minor alkaloid.
