Quantitation of Crocins and Picrocrocin in Saffron by HPLC: Application to Quality Control and Phytochemical Differentiation From Other Crocus Taxa<\/h1>\n

Abstract<\/h3>\n

A chromatographic method was developed and fully validated for the determination of the major saffron constituents, i.e., picrocrocin and five major crocins.<\/p>\n

Dried samples (styles of Crocus sativus and other Crocus taxa) were extracted with MeOH : water (1 : 1, v\/v), and chromatographic separation of the analytes was achieved by reversed-phase chromatography using a gradient elution.<\/p>\n

Full validation was performed using spiked samples with analytes, which were isolated, purified, and characterized by MS due to a lack of commercial standards.<\/p>\n

The method showed a good fit (r2 > 0.999) for all analytes with limit of quantitation values in the range of 1-15 \u00b5g\/mL, and demonstrated adequate intra- and inter-precision (< 15 % RSD) and accuracy (< 7 % RE).<\/p>\n

The method was applied to the analysis of various commercial saffron samples and of indigenous Crocus taxa and allowed for the first time the absolute quantitation of several Crocus components.<\/p>\n
