Fucoxanthin (all-trans-Fucoxanthin) is a carotenoid naturally found in certain algae, serving as an accessory pigment in the chloroplasts of brown algae and most other heterokonts, which imparts a brown or olive-green color. It exhibits anti-obesity, antioxidant, anti-diabetic, anticancer, and anti-inflammatory activities.

Crocin is a water-soluble carotenoid pigment of saffron (Crocus sativus L.). Crocin has anti-inflammatory, anti-oxidative, anti-apoptotic, anti-asthma, anti-cancer, and hypolipidemic effects.

Canthaxanthin (E 161g) is a red-orange carotenoid that belongs to the xanthophyll group. This naturally occurring pigment is present in bacteria, algae and some fungi.

Lycopene (ψ,ψ-Carotene) is a linear, unsaturated hydrocarbon carotenoid, the major red pigment in fruits such as tomatoes, pink grapefruit, apricots, red oranges, watermelon, rosehips, and guava. As a class, carotenoids are pigment compounds found in photosynthetic organisms (plants, algae, and some types of fungus), and are chemically characterized by a large polyene chain containing 35-40 carbon atoms; some carotenoid polyene chains are terminated by two 6-carbon rings. In animals, carotenoids such as lycopene may possess antioxidant properties which may retard aging and many degenerative diseases. As an essential nutrient, lycopene is required in the animal diet.

Urechistachykinin II acetate (Uru-TK II acetate) is an invertebrate rapid kinin-related peptide (TRPs) isolated from carotenoid worms, shows antimicrobial activities without a hemolytic effect

11-cis Retinal is a chromophore that binds to opsin in the mammalian visual system as an inverse agonist forming the inactive conformation of rhodopsin. When 11-cis retinal absorbs a photon of light, it isomerizes to form all-trans retinal beginning the phototransduction cycle, which is the basis for mammalian vision. A G121L mutation in opsin allows 11-cis retinal to bind as a partial agonist and activate rhodopsin in the absence of light. In a moth model of carotenoid deficiency-induced low visual sensitivity, 11-cis retinal application to compound eyes restored visual sensitivity almost completely.

Rehmannioside D is a carotenoid glycoside that existed in the roots of Rehmannia glutinosa.

Crocin (Gardenia Yellow) is a water-soluble carotenoid pigment of saffron (Crocus sativus L. ) that has been used as a spice for flavoring and coloring food preparations, and in Chinese traditional medicine as an anodyne or tranquilizer. Crocin suppresses tumor necrosis factor (TNF)alpha-induced apoptosis of pheochromocytoma (PC12) cells by modulating mRNA expressions of Bcl-2 family proteins, which trigger downstream signals culminating in caspase-3 activation followed by cell death. Crocin prevented the activation of nSMase by enhancing the transcription of gamma-glutamylcysteinyl synthase, which contributes to a stable glutathione supply that blocks the activity of nSMase.

β-Apo-8'-carotenal (Apocarotenal) is a carotenoid present in spinach and citrus fruits, utilized in fat-based foods (margarine, sauces, salad dressings), beverages, dairy products, and sweets.

Crocin-4, a carotenoid compound found in saffron, possesses potent antioxidant properties and can penetrate the brain. It effectively inhibits the aggregation and deposition of Aβ fibrils, making it useful for Alzheimer's Disease research. Additionally, Crocin-4 demonstrates antitumor and anti-inflammatory activities.

Antheraxanthin, a carotenoid, is a photoprotective pigment present in chromophyte algae [1].

Crocin IV (Dicrocin), a crocetin glycoside from the carotenoid pigments, exhibits significant antioxidant activity [1].

Norbixin, a carotenoid found in B. orellana, exhibits various biological activities including binding to the peroxisome proliferator-activated receptor γ (PPARγ) with a Ki of 1.15 µM in a cell-free assay. At a dosage of 47.7 mg/kg, norbixin effectively alleviates hyperglycemia, hyperinsulinemia, and insulin resistance, in addition to reducing serum lipid levels, cardiac thiobarbituric acid reactive substances (TBARS), and glutathione (GSH) in rat cardio-metabolic syndrome models. It also lowers serum levels of oxidized LDL, aortic protein oxidation, and the atherosclerotic area in a rabbit cholesterol-induced atherosclerosis model. Furthermore, norbixin, administered at 0.1 and 1 mg/kg per day, minimizes mercury-induced DNA damage in rat hepatocytes and leukocytes and prevents photoreceptor degeneration in an Abca4-/- Rdh8-/- mouse model of age-related macular degeneration (AMD).

Hepaxanthin is a carotenoid.

Capsorubin is a carotenoid with a variety of biological activities. capsorubin inhibited lipid peroxidation induced by 2,2′-azino(2,4-dimethylvaleronitrile) (AMVN) at a concentration of 167 μM. capsorubin (1 μM) reduced uvb-induced DNA strand breaks and apoptosis in human dermal fibroblasts. formation. It also inhibited the activation of ebvirus early antigen (EBV-EA) induced by 12-carnosine 13-acetate fobo in Raji cells.

β-Cryptoxanthin is isolated from Satsuma mandarin orange with an anti-stress effect. It is an oxygenated carotenoid and an antioxidant.

Urechistachykinin II (Uru-TK II) is an invertebrate rapid kinin-related peptide (TRPs) isolated from carotenoid worms.

Astaxanthin (trans-Astaxanthin) is a keto-carotenoid in the terpenes class of chemical compounds. It is classified as a xanthophyll but it is a carotenoid with no vitamin A activity. It is present in most red-colored aquatic organisms. Astaxanthin has shown to mediate anti-oxidant and anti-inflammatory actions. It may be found in fish feed or some animal food as a color additive.

Zeaxanthin is a dietary carotenoid that accumulates in the retina (particularly the macula) and has antioxidant activity that may improve obesity, prevent age-related macular degeneration, and protect against nonalcoholic steatohepatitis.
