FIELD: chemical or physical processes.
SUBSTANCE: group of inventions relates to a method of separating and purifying an isomer of (-)-ambroxide and a method of enhancing odor (-)-ambroxide. Methods include extraction of (-)-ambroxide from reaction mixture, containing (-)-ambroxide and one or more of compounds (II), (III) and (IV): 
, 
, 
, by selective crystallisation of (-)-ambroxide. After extraction of (-)-ambroxide does not contain or contains only olfactory acceptable amounts of compounds (II), (III) or (IV).
EFFECT: disclosed is a method of separating and purifying ambroxide.
