Crocus sativus is an herbaceous plant that belongs to family Iridaceae. It is commonly known as saffron and has been used for medicinal purposes since many centuries in India and other parts of the world. Saffron of commercial importance comprises of dried stigmas of the plant and is rich in flavonoids, vitamins, and carotenoids. Carotenoids represent the main components of saffron and their cleavage results in the formation of apocarotenoids such as crocin, picrocrocin, and safranal. Studies conducted during the past two decades have revealed the immense therapeutic potential of saffron...

The spice saffron is made from the dried stigmas of the plant Crocus sativus L. The main use of saffron is in cooking, due to its ability to impart colour, flavour and aroma to foods and beverages. However, from time immemorial it has also been considered a medicinal plant because it possesses therapeutic properties, as illustrated in paintings found on the island of Santorini, dated 1627 BC. It is included in Catalogues of Medicinal Plants and in the European Pharmacopoeias, being part of a great number of compounded formulas from the 16th to the 20th centuries...

Crocetin is the main component of saffron and exhibits anti-oxidative and anti-inflammatory effects. Neuroinflammation and oxidative stress have been recognized to play a crucial role in the pathogenesis of neuropathic pain. We investigated the effect of crocetin in a mouse model with neuropathic pain induced by spared nerve injury (SNI). Crocetin was intrathecally perfused at various doses for up to 12 days starting 3 days before the surgery. Behavioral tests were performed to determine pain sensitivity. The concentrations of proinflammatory cytokines tumor necrosis factor (TNF-α) and interleukin-1β (IL-1β) were measured to assess neuroinflammation...

Saffron, the stigma of Crocus sativus Linné (Iridaceae family), has been known to inhibit aggregation of β-amyloid, a nerve tissue protein. α-Synuclein (αS) is a 140-amino acid protein found abundantly in various regions of the brain. Its abnormal aggregation and accumulation in nerve tissue are said to cause neurodegenerative diseases such as Parkinson's disease, Lewy body dementia, and multiple-system atrophy. This study (part of this study was presented at the 137th Annual Meeting of the Pharmaceutical Society of Japan) examined the effects of saffron, its constituents (crocin-1, crocin-2, crocetin, and safranal), and crocetin structural analogs (hexadecanedioic acid, norbixin, and trans, trans-muconic acid) on αS aggregation, and αS fibril dissociation...

Saffron as a medicinal plant has many therapeutic effects. Phytochemical studies have reported that saffron is composed of at least four active ingredients which include crocin, crocetin, picrocrocin and safranal. The carotenoids of saffron are sensitive to oxygen, light, heat and enzymatic oxidization. However, regulation of these factors is required for saffron quality. Some pharmacologic effects of saffron and its active compounds include cardioprotective, neuroprotective, memory enhancer, antidepressant and anxiolytic...

Crocetin, one of the few colored apocarotenoids known in nature, is present in flowers and fruits and has long been used medicinally and as a colorant. Saffron is the main source of crocetin, although a few other plants produce lower amounts of this apocarotenoid. Notably, Buddleja davidii accumulates crocetin in its flowers. Recently, a carotenoid dioxygenase cleavage enzyme, CCD2, has been characterized as responsible for crocetin production in Crocus species. We searched for CCD2 homologues in B. davidii and identified several CCD enzymes from the CCD1 and CCD4 subfamilies...

Inhibition of lactate dehydrogenase (LDH) represents an innovative approach to tackle cancer because this peculiar glycolytic metabolism is characteristic of most invasive tumor cells. An investigation into the biological properties of saffron extracts led to the discover of their LDH-inhibition properties. In particular, the most important saffron components, crocetin, was found to inhibit LDH (IC50 = 54.9 ± 4.7 μM). This carotenoid was independently produced by chemical synthesis, and its LDH-inhibition properties manifested via its antiproliferative activity against two glycolytic cancer cell lines (A549 and HeLa, IC50 = 114...
