Typical chromatograms from HPLC–FLD analysis of aristolactam I and aristolactam II, the nitroreduction products of AA-I and AA-II, respectively, (A) in authentic standard solution mixture, and in soil samples collected from (B) wheat and (C) maize fields. Shown in the insets are the fluorescence excitation spectra of the chromatographic peaks at migration times of 6.1 (aristolactam II, 2) and 6.4 min (aristolactam I, 1). (D) Photos showing Aristolochia clematitis (indicated by red arrows) growing in wheat field in the endemic Village, Kutleš. (LU: Luminescence unit).
