Saffron is a plant from Crocus Sativus species which is one of the most valuable indigenous herbs in Iran and is known as the most expensive spice and red gold. Saffron stigma consists of three major constituents including crocin (water soluble caretenoid pigments), picocrocin (bitter glycoside tasting) and safranal (the major volatile constituents in saffron aroma). The aim of this study was determination and comparison of existed metabolites in different types of saffron based on their geographical origins using gas chromatography-mass spectroscopy techniques (GC-MS) and 13 volatile metabolites were determined and compared in different saffron samples from seven different regions of Khorasan Razavi province. These regions were Taybad, Neyshabour, torbate heydarieh, torbate jam, Zaveh and Kashmar.The results from statistical analysis (analysis of variance ANOVA followed by Duncan test) show that the level of metabolites were different in different regions and this can be the main reason of their discrimination against each other. These volatile metabolites were safranal, Megastigma-4,6(Z),8(Z)-triene, α-Guaiene, icosane and vitamine E. The results of this study show that in spite of similarities of constituents of these saffron samples, there are significant differences between the levels of metabolites in these regions although these region are close to each other. These differences show that these saffron can be applied in different purposes including pharmaceutical, food, cosmetic and health industries depending on their origin. Saffron of Torbat-e-jam is proper for food industries since it is rich in aroma and Taibad is proper for pharmaceutical, cosmetic and health industries. The quality of Kashmar saffron is worse than other regions.
