Urinary excretion of sulforaphane and its metabolites in the first overnight urine collections (~12 h) from 98 subjects in Qidong, China, who received 400 μmol of GR daily for 14 days (25, 36). Urinary excretion of free sulforaphane (SF) [○], and its major mercapturic acid conjugates: cysteinyl-SF [▲], and N-acetylcysteinyl-SF [=], as a function of total DTC excretion. Measurements of metabolites were for a single day, and are expressed as micromol of the specified metabolite, and normalized per mg creatinine.
