FIELD: medicine.
SUBSTANCE: method for preparing isotope-marked secondary metabolic products of fungi provides immobilised fungi growing on an inert carrier with an artificial fluid culture medium added. All carbon, nitrogen and/or sulphur atoms in the specified medium are substituted by stable isotopes chosen from the group including 13C, 15N, 33S and 34S. Also, an isotope-marked secondary metabolic product made of fungi is presented.
EFFECT: high-purity end product preparation.
