PREPARATION METHOD OF ARCTIGENIN INCLUDING FERMENTATION OF MICROORGANISM IN MEDIUM CONTAINING ARCTIUM LAPPA L.

摘要

PURPOSE: A method for preparing arctigenin using microorganisms is provided to effectively convert arctin to arctigenin. CONSTITUTION: A method for preparing arctigenin comprises a step of culturing microorganisms in a medium containing Arctium lappa L. extract. The extract is prepared using water and organic solvent. The microorganism is Saccharomyces cerevisiae, Aspergillus oryzae, Bacillus subtilis, or Lactobacillus plantarum. A method for manufacturing a cosmetic composition comprises a step of culturing the microorganisms in the medium containing Arctium lappa L. extract. A cosmetic composition contains Arctium lappa L. extract as an active ingredient.
