Cultivated saffron (Crocus sativus L.) boasts remarkable commercial value due to its possessing three pivotal metabolites: crocin, picrocrocin, and safranal. The significance of obtaining these metabolites, particularly crocin, from sources other than cultivated saffron has grown substantially, primarily driven by native wild saffron species in Iran. In this ongoing study, High-Performance Liquid Chromatography (HPLC) has been harnessed as a potent analytical tool for the identification of these metabolites in two wild saffron species, Khazar (C. caspius) and Ziba (C. specious), alongside the cultivated variety. Furthermore, bioinformatics tools have been employed to extract nucleotide and protein sequences, thereby facilitating the prediction of protein structures for genes integral to the biosynthesis process of these notable apocarotenoids in an in-silico manner. The research findings have showcased the presence of crocin across all analyzed samples, albeit in varying quantities. Specifically, the crocin content in the cultivated saffron, Ziba, and Khazar species accounted for 26.76%, 2.8%, and 0.74% of dry weight matter, respectively. However, the amount of picrocrocin and safranal metabolites in cultivated species was 8.4 and 0.03 percent, respectively, but there were no detectable amounts of these apocarotenoids in the studied wild species. , The existence of crocin in wild species has made hope for conducting research and searching in wild species for these effective substances and implementing breeding programs or genetic manipulation for the mentioned species.
