Chlorogenic acid is the major polyphenolic compound in coffee, isolated from the leaves and fruits of dicotyledonous plants. This compound, long known as an antioxidant, also slows the release of glucose into the bloodstream after a meal. Coffee is a complex mixture of chemicals that provides significant amounts of chlorogenic acid. The chlorogenic acid content of a 200 ml (7-oz) cup of coffee has been reported to range from 70-350 mg, which would provide about 35-175 mg of caffeic acid. The results of epidemiological research suggest that coffee consumption may help prevent several chronic diseases, including type 2 diabetes mellitus, Parkinsons disease and liver disease (cirrhosis and hepatocellular carcinoma). Most prospective cohort studies have not found coffee consumption to be associated with significantly increased cardiovascular disease risk. However, coffee consumption is associated with increases in several cardiovascular disease risk factors, including blood pressure and plasma homocysteine. At present, there is little evidence that coffee consumption increases the risk of cancer. (PMID:16507475, 17368041).

beta-Carotene

1,3,3-trimethyl-2-[(1E,3E,5E,7E,9E,11E,13E,15E,17E)-3,7,12,16-tetramethyl-18-(2,6,6-trimethylcyclohex-1-en-1-yl)octadeca-1,3,5,7,9,11,13,15,17-nonaen-1-yl]cyclohex-1-ene

C40H56 (536.4381776)


Beta-carotene is a cyclic carotene obtained by dimerisation of all-trans-retinol. A strongly-coloured red-orange pigment abundant in plants and fruit and the most active and important provitamin A carotenoid. It has a role as a biological pigment, a provitamin A, a plant metabolite, a human metabolite, a mouse metabolite, a cofactor, a ferroptosis inhibitor and an antioxidant. It is a cyclic carotene and a carotenoid beta-end derivative. Beta-carotene, with the molecular formula C40H56, belongs to the group of carotenoids consisting of isoprene units. The presence of long chains of conjugated double bonds donates beta-carotene with specific colors. It is the most abundant form of carotenoid and it is a precursor of the vitamin A. Beta-carotene is composed of two retinyl groups. It is an antioxidant that can be found in yellow, orange and green leafy vegetables and fruits. Under the FDA, beta-carotene is considered as a generally recognized as safe substance (GRAS). Beta-Carotene is a natural product found in Epicoccum nigrum, Lonicera japonica, and other organisms with data available. Beta-Carotene is a naturally-occurring retinol (vitamin A) precursor obtained from certain fruits and vegetables with potential antineoplastic and chemopreventive activities. As an anti-oxidant, beta carotene inhibits free-radical damage to DNA. This agent also induces cell differentiation and apoptosis of some tumor cell types, particularly in early stages of tumorigenesis, and enhances immune system activity by stimulating the release of natural killer cells, lymphocytes, and monocytes. (NCI04) beta-Carotene is a metabolite found in or produced by Saccharomyces cerevisiae. A carotenoid that is a precursor of VITAMIN A. Beta carotene is administered to reduce the severity of photosensitivity reactions in patients with erythropoietic protoporphyria (PORPHYRIA, ERYTHROPOIETIC). See also: Lycopene (part of); Broccoli (part of); Lycium barbarum fruit (part of). Beta-Carotene belongs to the class of organic compounds known as carotenes. These are a type of polyunsaturated hydrocarbon molecules containing eight consecutive isoprene units. Carotenes are characterized by the presence of two end-groups (mostly cyclohexene rings, but also cyclopentene rings or acyclic groups) linked by a long branched alkyl chain. Beta-carotene is therefore considered to be an isoprenoid lipid molecule. Beta-carotene is a strongly coloured red-orange pigment abundant in fungi, plants, and fruits. It is synthesized biochemically from eight isoprene units and therefore has 40 carbons. Among the carotenes, beta-carotene is distinguished by having beta-rings at both ends of the molecule. Beta-Carotene is biosynthesized from geranylgeranyl pyrophosphate. It is the most common form of carotene in plants. In nature, Beta-carotene is a precursor (inactive form) to vitamin A. Vitamin A is produed via the action of beta-carotene 15,15-monooxygenase on carotenes. In mammals, carotenoid absorption is restricted to the duodenum of the small intestine and dependent on a class B scavenger receptor (SR-B1) membrane protein, which is also responsible for the absorption of vitamin E. One molecule of beta-carotene can be cleaved by the intestinal enzyme Beta-Beta-carotene 15,15-monooxygenase into two molecules of vitamin A. Beta-Carotene contributes to the orange color of many different fruits and vegetables. Vietnamese gac and crude palm oil are particularly rich sources, as are yellow and orange fruits, such as cantaloupe, mangoes, pumpkin, and papayas, and orange root vegetables such as carrots and sweet potatoes. Excess beta-carotene is predominantly stored in the fat tissues of the body. The most common side effect of excessive beta-carotene consumption is carotenodermia, a physically harmless condition that presents as a conspicuous orange skin tint arising from deposition of the carotenoid in the outermost layer of the epidermis. Yellow food colour, dietary supplement, nutrient, Vitamin A precursor. Nutriceutical with antioxidation props. beta-Carotene is found in many foods, some of which are summer savory, gram bean, sunburst squash (pattypan squash), and other bread product.

Lutein

(1R,4R)-4-[(1E,3E,5E,7E,9E,11E,13E,15E,17E)-18-[(4R)-4-hydroxy-2,6,6-trimethylcyclohex-1-en-1-yl]-3,7,12,16-tetramethyloctadeca-1,3,5,7,9,11,13,15,17-nonaen-1-yl]-3,5,5-trimethylcyclohex-2-en-1-ol

C40H56O2 (568.4280076)


Lutein is a common carotenoid xanthophyll found in nature. Carotenoids are among the most common pigments in nature and are natural lipid-soluble antioxidants. Lutein is one of the two carotenoids (the other is zeaxanthin) that accumulate in the eye lens and macular region of the retina with concentrations in the macula greater than those found in plasma and other tissues. Lutein and zeaxanthin have identical chemical formulas and are isomers, but they are not stereoisomers. The main difference between them is in the location of a double bond in one of the end rings. This difference gives lutein three chiral centers whereas zeaxanthin has two. A relationship between macular pigment optical density, a marker of lutein and zeaxanthin concentration in the macula, and lens optical density, an antecedent of cataractous changes, has been suggested. The xanthophylls may act to protect the eye from ultraviolet phototoxicity via quenching reactive oxygen species and/or other mechanisms. Some observational studies have shown that generous intakes of lutein and zeaxanthin, particularly from certain xanthophyll-rich foods like spinach, broccoli, and eggs, are associated with a significant reduction in the risk for cataracts (up to 20\\\\\%) and age-related macular degeneration (up to 40\\\\\%). While the pathophysiology of cataract and age-related macular degeneration is complex and contains both environmental and genetic components, research studies suggest dietary factors including antioxidant vitamins and xanthophylls may contribute to a reduction in the risk of these degenerative eye diseases. Further research is necessary to confirm these observations (PMID: 11023002). Lutein is a carotenol. It has a role as a food colouring and a plant metabolite. It derives from a hydride of a (6R)-beta,epsilon-carotene. Lutein is an xanthophyll and one of 600 known naturally occurring carotenoids. Lutein is synthesized only by plants and like other xanthophylls is found in high quantities in green leafy vegetables such as spinach, kale and yellow carrots. In green plants, xanthophylls act to modulate light energy and serve as non-photochemical quenching agents to deal with triplet chlorophyll (an excited form of chlorophyll), which is overproduced at very high light levels, during photosynthesis. Lutein is a natural product found in Eupatorium cannabinum, Hibiscus syriacus, and other organisms with data available. Lutein is lutein (LOO-teen) is a oxygenated carotenoid found in vegetables and fruits. lutein is found in the macula of the eye, where it is believed to act as a yellow filter. Lutein acts as an antioxidant, protecting cells against the damaging effects of free radicals. A xanthophyll found in the major LIGHT-HARVESTING PROTEIN COMPLEXES of plants. Dietary lutein accumulates in the MACULA LUTEA. See also: Calendula Officinalis Flower (part of); Corn (part of); Chicken; lutein (component of) ... View More ... Pigment from egg yolk and leaves.

beta-Cryptoxanthin

(1R)-3,5,5-trimethyl-4-[(1E,3E,5E,7E,9E,11E,13E,15E,17E)-3,7,12,16-tetramethyl-18-(2,6,6-trimethylcyclohex-1-en-1-yl)octadeca-1,3,5,7,9,11,13,15,17-nonaen-1-yl]cyclohex-3-en-1-ol

C40H56O (552.4330926)


beta-Cryptoxanthin has been isolated from abalone, fish eggs, and many higher plants. beta-Cryptoxanthin is a major source of vitamin A, often second only to beta-carotene, and is present in fruits such as oranges, tangerines, and papayas (PMID: 8554331). Frequent intake of tropical fruits that are rich in beta-cryptoxanthin is associated with higher plasma beta-cryptoxanthin concentrations in Costa Rican adolescents. Papaya intake was the best food predictor of plasma beta-cryptoxanthin concentrations. Subjects that frequently consumed (i.e. greater or equal to 3 times/day) tropical fruits with at least 50 micro g/100 g beta-cryptoxanthin (e.g. papaya, tangerine, orange, watermelon) had twofold the plasma beta-cryptoxanthin concentrations of those with intakes of less than 4 times/week (PMID: 12368412). A modest increase in beta-cryptoxanthin intake, equivalent to one glass of freshly squeezed orange juice per day, is associated with a reduced risk of developing inflammatory disorders such as rheumatoid arthritis (PMID: 16087992). Higher prediagnostic serum levels of total carotenoids and beta-cryptoxanthin were associated with lower smoking-related lung cancer risk in middle-aged and older men in Shanghai, China (PMID: 11440962). Consistent with inhibition of the lung cancer cell growth, beta-cryptoxanthin induced the mRNA levels of retinoic acid receptor beta (RAR-beta) in BEAS-2B cells, although this effect was less pronounced in A549 cells. Furthermore, beta-cryptoxanthin transactivated the RAR-mediated transcription activity of the retinoic acid response element. These findings suggest a mechanism of anti-proliferative action of beta-cryptoxanthin and indicate that beta-cryptoxanthin may be a promising chemopreventive agent against lung cancer (PMID: 16841329). Cryptoxanthin is a natural carotenoid pigment. It has been isolated from a variety of sources including the petals and flowers of plants in the genus Physalis, orange rind, papaya, egg yolk, butter, apples, and bovine blood serum. In a pure form, cryptoxanthin is a red crystalline solid with a metallic lustre. It is freely soluble in chloroform, benzene, pyridine, and carbon disulfide. In the human body, cryptoxanthin is converted into vitamin A (retinol) and is therefore considered a provitamin A. As with other carotenoids, cryptoxanthin is an antioxidant and may help prevent free radical damage to cells and DNA, as well as stimulate the repair of oxidative damage to DNA. Structurally, cryptoxanthin is closely related to beta-carotene, with only the addition of a hydroxyl group. It is a member of the class of carotenoids known as xanthophylls. Beta-cryptoxanthin is a carotenol that exhibits antioxidant activity. It has been isolated from fruits such as papaya and oranges. It has a role as a provitamin A, an antioxidant, a biomarker and a plant metabolite. It derives from a hydride of a beta-carotene. beta-Cryptoxanthin is a natural product found in Hibiscus syriacus, Cladonia gracilis, and other organisms with data available.

C40H56O2 (568.4280076)


Zeaxanthin is a carotenoid xanthophyll and is one of the most common carotenoid found in nature. It is the pigment that gives corn, saffron, and many other plants their characteristic color. Zeaxanthin breaks down to form picrocrocin and safranal, which are responsible for the taste and aroma of saffron Carotenoids are among the most common pigments in nature and are natural lipid soluble antioxidants. Zeaxanthin is one of the two carotenoids (the other is lutein) that accumulate in the eye lens and macular region of the retina with concentrations in the macula greater than those found in plasma and other tissues. Lutein and zeaxanthin have identical chemical formulas and are isomers, but they are not stereoisomers. The main difference between them is in the location of a double bond in one of the end rings. This difference gives lutein three chiral centers whereas zeaxanthin has two. A relationship between macular pigment optical density, a marker of lutein and zeaxanthin concentration in the macula, and lens optical density, an antecedent of cataractous changes, has been suggested.

The novel carbohydrate-derived b-carboline, 1-pentahydroxypentyl-1,2,3,4-tetrahydro-b-carboline-3-carboxylic acid, was identified in fruit- and vegetable-derived products such as juices, jams, and tomato sauces. This compound occurred as two diastereoisomers, a cis isomer (the major compound) and a trans isomer, ranging from undetectable amounts to 6.5 ug/g. Grape, tomato, pineapple, and tropical juices exhibited the highest amount of this alkaloid (up to 3.8 mg/L), whereas apple, banana, and peach juices showed very low or nondetectable levels. This tetrahydro-b-carboline was also found in jams (up to 0.45 ug/g), and a relative high amount was present in tomato concentrate (6.5 ug/g) and sauce (up to 1.8 ug/g). This b-carboline occurred in fruit-derived products as a glycoconjugate from a chemical condensation of d-glucose and l-tryptophan that is highly favored at low pH values and high temperature. Production, processing treatments, and storage of fruit juices and jams can then release this b-carboline. Fruit-derived products and other foods containing this compound might be an exogenous dietary source of this glucose-derived tetrahydro-b-carboline.(PMID: 12137498) [HMDB] Window width to select the precursor ion was 3 Da.; CONE_VOLTAGE is 20 V.; This record was created by the financial support of MEXT/JSPS KAKENHI Grant Number 19HP8024 to the Mass Spectrometry Society of Japan.
