Picrocrocin is a monoterpene glycoside precursor of safranal.During the drying process picrocrocin liberates the aglycone (HTCC, C10H16O2;MW168)due to Glucosidase action which is then transformed to safranal by dehydration. It is found in the spice saffron, which comes from the crocus flower. Picrocrocin has a bitter taste and is the chemical most responsible for the taste of saffron.
It is believed that picrocrocin is a degradation product of the carotenoid zeaxanthinRef???.
