Overview

Randomized trial assesses the authenticity of essential oils, suggesting effective quality control methods.

Key Points

  • The aim is to evaluate the chemical composition and authenticity of rosemary and laurel essential oils.
  • Analyzed chemical composition and antioxidant activity of essential oils from the Slovenian market.
  • Utilized compound-specific isotope analysis to identify isotopic markers for adulteration.
  • Developed methodology evaluated for sensitivity to differentiate between natural and synthetic origins.
  • 1,8-cineole identified as the most abundant compound in both essential oils.
  • Lower concentration VOCs demonstrated higher antioxidant activity compared to more abundant counterparts.
  • Adulteration detectable when synthetic compounds exceed 19% for linalool and 47% for α-pinene.
