Abstract
Carnosic acid is obtained by extracting sage and rosemary with an apolar solvent, contacting the extract with an adsorbent material to separate carnosic acid from apolar compounds of the extract, desorbing the adsorbent with a polar solvent and then evaporating the solvent to obtain a residue containing carnosic acid. The carnosic acid contained in the residue may be purified by crystallizing it from the residue.
