species-specific PCR and real-time PCR with EvaGreen dye targeting the ITS region of Carthamus tinctorius L. (safflower) were successfully developed. A normalised real-time PCR approach was also proposed in the range of 0.1–20% (w/w) of safflower in saffron, which was successfully validated and applied to commercial saffron samples (stigmas, powders and seasonings).
