The chapter provides a comprehensive overview on methodologies used for radio-labeling of brassinosteroids as one of the newest class of phytohormones. Discussed labeling strategies are lined up in terms of reached specific activities (SA) of brassinosteroids (BRs) as a key parameter for further utilization of such labeled drugs. The chapter is focused on two key natural radio-isotopes (tritium and carbon-14) used for drug tracing in pharmaceutical research.
