Characterisation of secondary metabolites in saffron from central Italy (Cascia, Umbria)

The results of chromatographic analyses showed that the samples dried in the milder conditions had the lowest content of secondary metabolites. Moreover the sample dried at 60 °C for 55 min presented the highest contents of trans-crocin-4 and picrocrocin, while safranal was most represented in saffron dried at 55 °C for 95 min.
