Article Synopsis
  • The study aimed to assess the effectiveness of combining CO2 supercritical fluid extraction (SFE) with molecular distillation (MD) for extracting and purifying the volatile components of the Chinese herbal medicine Ligusticum wallichii Franch.
  • SFE successfully extracted 45 chemical constituents, but MD further refined the extract, leaving 39 constituents and altering their concentrations.
  • The findings suggest that this combined method is superior to using SFE alone for handling the extraction and purification of volatile components in Chinese herbs.
