Phytosterols in food


  • Fast separation of phytosterols
  • Direct detection w/o derivatization
  • Boron-doped Diamond WE
  • LOD 100 – 300 nM (0.1 – 0.3 pmol, on-column)

Plant sterols and plant stanols, known commonly as phytosterols, are plant-derived compounds that are structurally related to cholesterol. Important food sources of phytosterols include unrefined vegetable oils, whole grains, nuts, seeds, and legumes. Sterols can be electrochemically detected without derivatization, on boron-doped diamond (BDD) electrodes at high potentials. This note shows the proof of principle for the fast and sensitive analysis of Phytosterols using the ALEXYS Analyzer.
