This work intended to develop DNA-based methods to detect and quantify safflower as an adulterant in saffron. Species-specific PCR and real-time PCR with EvaGreen dye targeting the ITS region of Carthamus tinctorius L. (safflower) were successfully proposed. The assays allowed absolute and relative sensitivities of 2pg of safflower DNA (∼1.4 DNA copies) and 0.1% of safflower in saffron (Crocus sativus...
Saffron (Crocus sativus) is the most expensive spice in the world. As a consequence, saffron has frequently been associated with an unrivalled degree of adulteration. The aim of this work was searching for DNA-barcode candidates as molecular markers to differentiate C. sativus from allied species and assessing the authenticity of saffron. New primers were specifically designed targeting three DNA...
