Safranal as a fat-soluble substance and Crocetin are bitter, however, the bitterness of saffron caused by another component called Picrocrocin.
Studies indicated that those flavonoids such as proteins, resins, amino acids, lycopene, starch, and other compounds are present in saffron stigmas.
Water is the principal component of saffron, it constitutes 14 to 16 percent of the stigma, other substances of this plant include nitrogenous matters, extract soluble, sugars, fibers, volatile oil, total ashes which forms 11 to 13 %, 41-44 %, 12-15 %, 4-5 %, 0.6-0.9 %, 4-6 %, respectively. There are two substantial vitamins in the stigma of saffron includes riboflavin and thiamine and a small amount of β-carotene.

Pharmacological activities of saffron and its constituents:



It has been proved that Ethanolic and aqueous saffron extract, Saffron petal extract and the main constituents of saffron; Crocin and Safranal have an antidepressant effect in experimental studies. The effect of saffron capsules on depression has been investigated in another study. The results showed no side effects.

Withdrawal syndrome

The stigma of saffron and its component administered in a dose-dependent manner, it raised the dopamine and glutamate levels in the brain and decrease withdrawal syndrome by interacting with the opioid system. Another study has been done and the results of using Crocin showed that it decreased withdrawal signs; Saffron extract had the same effect.

Spatial memory:

C. sativus and its main constituent Crocin solution and saffron extract have an important role in cognition. Saffron and saffron extract in the treatment of Alzheimer’s disease (AD) in patients with mild, moderate and severe AD. For the treatment of Parkinson as a disorder of neural processes in the brain, Crocetin was administered in animal models. The results demonstrated a certain anticonvulsant activity of the active saffron components.
