Coumarins were quantified using the calibration curve obtained for compound 5.
§
Furanocoumarins were quantified using the calibration curve obtained for compound 3. “Traces” means that the compound was detected but not quantified (concentration under LOQ). n.d. means not detected (concentration under LOD).
