Characterization and geographical discrimination of saffron from Greece, Spain, Iran, and Morocco based on volatile and bioactivity markers, using chemometrics

In the present study saffron samples from Greece, Spain, Iran, and Morocco, collected during harvesting years 2005–2014, were characterized and classified according to geographical origin using volatile compounds and selected bioactivity parameters. The volatile compounds of saffron were semi-quanti...

Zusammenfassung:	In the present study saffron samples from Greece, Spain, Iran, and Morocco, collected during harvesting years 2005–2014, were characterized and classified according to geographical origin using volatile compounds and selected bioactivity parameters. The volatile compounds of saffron were semi-quantified using headspace solid-phase microextraction in combination with gas chromatography/mass spectrometry. Bioactivity parameters such as total phenolic content (TPC), radical scavenging activity (%RSA), and ferric reducing antioxidant power (FRAP) were determined using spectrophotometric assays. Results showed that significant variations ( P
