Extraction of Propofol from Whole Blood

06 October 2015

A new poster from Biotage labs demonstrates the suitability of ISOLUTE® SLE+ for the rapid and reliable extraction of Propofol from whole blood, prior to GC/MS analysis.

 

Propofol is used in clinical environments to induce states of anesthesia or reduced sensitivity during surgical procedures. However, it also has the potential to be abused for short-term hallucinations and euphoric effects, and with a very small therapeutic range, unanticipated fatal results are possible.

Key Findings

  • The addition of tetrabutylammonium hydroxide following extraction and prior to evaporation was critical to prevent
    evaporative losses of Propofol.
  • MTBE and ethyl acetate both offer high percentage recovery of Propofol. However MTBE offers cleaner extracts and chromatographic baselines which allow for a lower limit of quantitation.
  • Analysis of phospholipids using LC-MS/MS, demonstrates the optimized methods on ISOLUTE® SLE+ do not allow breakthrough of these whole blood components into the extract and is applicable and transferrable to LC as an end point.
