Description

General description

Crocin (CR) is a water-soluble carotenoid found in Gardenia jasmi-noides Ellis and Crocus sativus (saffron). It has two D-gentiobioside glycosyl esters in its structure. CR is one of the major bioactive compounds of saffron contributing to its red color.

A highly unsaturared diterpene dicarboxylic acid ester found in saffron.

Application

Crocin has been used:

• as a reference standard to detect its presence in Crocus sativus L. extract using high-performance liquid chromatography technique
• to investigate its protective effects as an antioxidant and anti-inflammatory agent against doxorubicin-induced nephrotoxicity in rats
• to test antitumor effects and its role in promoting autophagy and apoptosis and inhibiting the progression of cervical cancer on SiHa cells and female BALB/c nude mice
• as a co-treatment with cisplatin to test its protective effect against cisplatin (CIS)-induced testicular toxicity in rats

Biochem/physiol Actions

Crocin alleviates some ethanol-induced impairments of learning and prevents ethanol-induced inhibition of hippocampal long-term potentiation (LTP), a form of activity-dependent synaptic plasticity that may underly learning and memory. Related CNS effects are specific to the digentiobiose ester; crocetin glucose gentiobiose ester is half as potent, and the diglucose ester has no effect at all.

Crocin exerts antioxidant, anti-inflammation, anti-cancer, antidegenerative, and antidiabetic properties.
