FIELD: biotechnology, microbiology. SUBSTANCE: method involves using strains of Bacillus megaterium that are able to grow in the presence of high concentration of colchicon transformable substrate. Biotransformation involves substitution of hydroxyl or methoxy-group at position C-3 of aromatic ring of substrate for O-glycosyl residue. Method provides high selectivity and effectiveness of biotransformation. EFFECT: improved preparing method. 14 cl, 1 tbl, 8 ex
