¹³C‐enrichment (δ ¹³C in ⁰/₀₀) in brain sections, organs, and urine. WT mice received intravenously 0.2 g per kg body weight ¹³C‐labelled 2´FL. 12 h after the last of three partial dosages, mice were sacrificed and organs and urine were collected as described in the section materials and methods (treated n = 5, controls n = 3). Data are depicted as box plots with median and min–max whiskers (differences to corresponding controls were significant at ***p < 0.001).
