Description

It has been documented that saffron was used as a food or spicy plant product for culinary purposes in Achamenian Imperial court. The underground parts of the plant, corms or bulbs, can be used to produce new plant as this plant has no seed propagation. The outstanding feature of the colored flowers of saffron is three stigmas (25-30 mm long), drooped over the petals. The flower has also three yellow stamens, which do not contain the active compounds and usually are not collected. Each bulb produces one to seven flowers. It seems that the cultivated species has originated as a natural hybrid so that it has been selected for its long stigmas and maintained ever since. The flower of C. sativa is a light purple, but it is the thread-like reddish-colored stigma of the flower that is valued both as a spice and as a natural colorant. It takes about 36,000 flowers to yield just 1 pound of stigmas. Over 200,000 dried stigmas (obtained from about 70,000 flowers) yield 500 g of pure saffron.

• The main components of saffron are crocin, picrocrocin and safranal.

• The stigmas of C. sativus are known to contain carotenoids, α-crocetin and glycoside crocin (responsible for saffron yellow color) and picrocrocin, the aglyconesafranal (responsible for saffron aroma)

               - Picrocrocin (C16H26O7, 4-(β-d-glucopyranosyloxy)-2,6,6-trimethyl-1-cyclohexene-1-carbox-aldehyde) is the substance responsible for the bitter taste of saffron. 

               - The other color compounds of saffron are carotenoids and glycosidic, alpha-carotene, beta-carotene, lycopene, Zeaxanthingentiobioside, glycoside, gentio-glycoside, beta-crocetin di-glycoside and gama-crocetin.

• Antioxidant carotenoids lycopene and zeaxanthin and vitamin B2.

               - Saffron and its constituentscrocin and safranal are also shown to be potent oxygen radical scavengers.

               - Saffron also has trace amounts of thiamine and riboflavin.

• More than 150 compounds have been identified in saffron stigma including colored carotenoids (e.g. crocetin and crocins as glycosidic derivatives), colorless monoterpene aldehydes, volatile agents (e.g. safranal and picrocrocin which are the bitter components), etc.  The traces of non-glycosylated carotenoids unrelated to crocetin are β-carotene, lycopene and zea-xanthin.

                - Crocin belongs to a group of natural carotenoid. It has a deep red color, forms crystals with a melting point of 186 oC and is easily soluble in water. Crocin is responsible for the color of saffron.  It is the main pigment of saffron (approx. 80% of pigment content). Pure crocin can be isolated from saffron extract and is directly crystallized. Crocin is not orally absorbed. Crocins are hydrolyzed to crocetin before or during intestinal absorption, and the absorbed crocetin is partly metabolized to mono and diglucuronide conjugates. Crocins, accounting for almost 6–16% of saffron dry weight.

• Flavonoids especially lycopene, amino acids, proteins, starch, resins and other compounds have also been shown to be present in saffron.

• Anthocyanins have been isolated from the blue perianth segments of C. antalyensis and identified as delphinidin 3-O-(β-d-glucopyranoside)-5-O-(6-O-malonyl-β-d-glucopyranoside and petudin 3,7-di-O-(β-d-glucopyranoside 3,7-di-O-β-d-glucoside of delphinidin 3,5-di-O-β-d-glucosides of delphinidin and petunidin.

• Specific essential oils of the flower contribute to the sweet fragrance of saffron. The principal constituent of total essential oil of C. sativus L., safranal is a carboxaldehyde volatile compound formed by deglucosylation of picrocrocin.

                - The essential oils also comprised several terpene aldehydes, ketones, and terpene derivatives (pinene and cineol).

• The secondary metabolites present in the petals of C. sativus L. are tannins, anthocyanins, and flavonoids, which include rutin, quercetin, luteolin, hesperidin, and bioflavonoids.
