Supramolecular complexes of glycyrrhizic acid (GA) and salicylic acid (SA) in various mole ratios of 1:1, 2:1, 4:1, and 8:1 were prepared for the first time. Their IR and UV spectra indicated that a complex with SA did form. The supramolecular complex with a 2:1 ratio, which was called DAG-1, had the optimal molecular ratio of GA and SA for high biological activity. DAG-1 at a concentration of 10 –7 M induced antioxidantenzyme (catalase, peroxidase, superoxide dismutase) activity and stimulated cotton growth and development under model chloride salinity conditions.
