Molecular species fingerprinting and quantitative analysis of saffron (<i>Crocus sativus</i>L.) for quality control by MALDI mass spectrometry

Abstract

+ (-0.1214 ± 0.0086). No matrix effects were observed and good results were obtained with respect to instrumental repeatability (*RSD% < 2%) and LOD (1.1%). The analysis of commercial samples of saffron using the proposed approach showed the suitability of the method for routine analysis (minimal sample preparation and very short measuring time per sample).
