Picrocrocin is a monoterpene glycoside precursor of safranal. It is found in the spice saffron, which comes from the crocus flower.^[1] Picrocrocin has a bitter taste, and is the chemical most responsible for the taste of saffron.

During the drying process, picrocrocin liberates the aglycone (HTCC, C₁₀H₁₆O₂) due to the action of the enzyme glucosidase. The aglycone is then transformed to safranal by dehydration. Picrocrocin is a degradation product of the carotenoid zeaxanthin.{{Citation needed|date=August 2009}}
