MQL: method quantification limit (for codeine, papaverine and noscapine: 0.24 µg/kg; for thebaine: 2.40 µg/kg; and for oripavine: 240 µg/kg). ND: not detected. To quantify seed samples, matrix-matched calibration was used with internal standard (morphine: y = 0.006x − 0.182; codeine: y = 0.005x + 0.117; thebaine: y = 0.020x + 1.853; papaverine: y = 0.069x + 6.739; noscapine: y = 0.080x + 6.049; oripavine: y = 0.002x + 0.009).
