Abstract
The purpose of this paper is to report the analyses of stigmas from different samples of C. sativus cultivated in Italy (2 samples from Tuscany and 2 from Umbria, provided by Associazione Zafferano Italiano) in order to characterize this product from a quality point of view. The identification of crocins, safranal, picrocrocin, and flavonols was carried out by HPLC/DAD analyses of the hydroalcoholic (EtOH:H2O 70:30, pH 3.2) extracts. Moreover, the quantitative analyses of an aqueous extract was carried out by spectrophotometric analyses (ISO/TS 3632-2:2003). Saffron aqueous extracts (ISO/TS 3632-2:2003, enriched with D2O 10% vol. for the locking signal and DSS 0.01 mM as internal standard) were also analyzed by high resolution NMR (400MHz), to further characterize this product
