The search of inhibitors of the myrosinase enzyme and also enzymes able to transform the glucosinolates into non-toxic combinations has been carried out among the water extracts of the plants row. The inhibitor activity of the water extract of Arctostaphylos uva-ursi and its foresee acting outset-hydroquinone have been discovered. The direct dependence of the glucosinolates decompose degree from concentration of hydroquinone and quinone has been determined. The cultivation of Brassica napus cut seeds by quinone in correlation 1:100 (m:m) stopped the glucosinolates decomposition by endogenous myrosinase for 50%.
