The maximum level refers to the lowerbound sum of the following 21 pyrrolizidine alkaloids:
— intermedine/lycopsamine, intermedine-N-oxide/lycopsamine-N-oxide,
— senecionine/senecivernine, senecionine-N-oxide/senecivernine-N-oxide,
— seneciphylline, seneciphylline-N-oxide,
— retrorsine, retrorsine-N-oxide,
— echimidine, echimidine-N-oxide,
— lasiocarpine, lasiocarpine-N-oxide,
— senkirkine,
— europine, europine-N-oxide,
— heliotrine and heliotrine-N-oxide
and the following additional 14 pyrrolizidine alkaloids known to co-elute with one or more of the above identified 21 pyrrolizi dine alkaloids, making use of certain currently used analytical methods:
— indicine, echinatine, rinderine (possible co-elution with lycopsamine/intermedine)
— indicine-N-oxide, echinatine-N-oxide, rinderine-N-oxide (possible co-elution with lycopsamine-N-oxide/intermedine-N-oxide)
— integerrimine (possible co-elution with senecivernine/senecionine)
— integerrimine-N-oxide (possible co-elution with senecivernine-N-oxide/senecionine-N-oxide)
— heliosupine (possible co-elution with echimidine)
— heliosupine-N-oxide (possible co-elution with echimidine-N-oxide)
— spartioidine (possible co-elution with seneciphylline)
— spartioidine-N-oxide (possible co-elution with seneciphylline-N-oxide)
— usaramine (possible co-elution with retrorsine)
— usaramine N-oxide (possible co-elution with retrorsine N-oxide)
Pyrrolizidine alkaloids, which can be individually and separately identified with the used method of analysis, shall be quantified and included in the sum.
