Saffron is one of the oldest natural dyestuffs and is obtained from the dried stigmata of Crocus sativus L. The yellowness of saffron results from the presence of crocins (glycosyl esters of crocetin). In this report we present the identification and characterization of multiple forms of crocins from whole saline saffron extracts using direct MALDI MS and MS/MS of glycosyl esters of crocetin and of their corresponding Hydrazine tagged products.
