Arbutin
Hydroquinone O-beta-D-glucopyranoside is a monosaccharide derivative that is hydroquinone attached to a beta-D-glucopyranosyl residue at position 4 via a glycosidic linkage. It has a role as a plant metabolite and an Escherichia coli metabolite. It is a beta-D-glucoside and a monosaccharide derivative. It is functionally related to a hydroquinone. Extracted from the dried leaves of bearberry plant in the genus Arctostaphylos and other plants commonly in the Ericaceae family, arbutin is a beta-D-glucopyranoside of [DB09526]. It is found in foods, over-the-counter drugs, and herbal dietary supplements. Most commonly, it is an active ingredient in skincare and cosmetic products as a skin-lightening agent for the prevention of melanin formation in various skin conditions that involve cutaneous hyperpigmentation or hyperactive melanocyte function. It has also been used as an anti-infective for the urinary system as well as a diuretic. Arbutin is available in both natural and synthetic forms; it can be synthesized from acetobromglucose and [DB09526]. Arbutin is a competitive inhibitor of tyrosinase (E.C.1.14.18.1) in melanocytes, and the inhibition of melanin synthesis at non-toxic concentrations was observed in vitro. Arbutin was shown to be less cytotoxic to melanocytes in culture compared to [DB09526]. Arbutin is a natural product found in Grevillea robusta, Halocarpus biformis, and other organisms with data available.

Arbutin, also known as hydroquinone-O-beta-D-glucopyranoside or P-hydroxyphenyl beta-D-glucopyranoside, is a member of the class of compounds known as phenolic glycosides. Phenolic glycosides are organic compounds containing a phenolic structure attached to a glycosyl moiety. Some examples of phenolic structures include lignans, and flavonoids. Among the sugar units found in natural glycosides are D-glucose, L-Fructose, and L rhamnose. Arbutin is soluble (in water) and a very weakly acidic compound (based on its pKa). Arbutin can be found in a number of food items such as guava, lingonberry, irish moss, and rowal, which makes arbutin a potential biomarker for the consumption of these food products. Arbutin is a glycoside; a glycosylated hydroquinone extracted from the bearberry plant in the genus Arctostaphylos among many other medicinal plants, primarily in the Ericaceae family. Applied topically, it inhibits tyrosinase and thus prevents the formation of melanin. Arbutin is therefore used as a skin-lightening agent. Very tiny amounts of arbutin are found in wheat, pear skins, and some other foods. It is also found in Bergenia crassifolia. Arbutin was also produced by an in vitro culture of Schisandra chinensis . A monosaccharide derivative that is hydroquinone attached to a beta-D-glucopyranosyl residue at position 4 via a glycosidic linkage. Arbutin is found in apple.

Quercetin
Quercetin appears as yellow needles or yellow powder. Converts to anhydrous form at 203-207 °F. Alcoholic solutions taste very bitter. (NTP, 1992) Quercetin is a pentahydroxyflavone having the five hydroxy groups placed at the 3-, 3-, 4-, 5- and 7-positions. It is one of the most abundant flavonoids in edible vegetables, fruit and wine. It has a role as an antibacterial agent, an antioxidant, a protein kinase inhibitor, an antineoplastic agent, an EC 1.10.99.2 [ribosyldihydronicotinamide dehydrogenase (quinone)] inhibitor, a plant metabolite, a phytoestrogen, a radical scavenger, a chelator, an Aurora kinase inhibitor and a geroprotector. It is a pentahydroxyflavone and a 7-hydroxyflavonol. It is a conjugate acid of a quercetin-7-olate. Quercetin is a flavonol widely distributed in plants. It is an antioxidant, like many other phenolic heterocyclic compounds. Glycosylated forms include RUTIN and quercetrin. Quercetin is a metabolite found in or produced by Escherichia coli (strain K12, MG1655). Quercetin is a flavonoid found in many foods and herbs and is a regular component of a normal diet. Extracts of quercetin have been used to treat or prevent diverse conditions including cardiovascular disease, hypercholesterolemia, rheumatic diseases, infections and cancer but have not been shown to be effective in clinical trials for any medical condition. Quercetin as a nutritional supplement is well tolerated and has not been linked to serum enzyme elevations or to episodes of clinically apparent liver injury. Quercetin is a natural product found in Lotus ucrainicus, Visnea mocanera, and other organisms with data available. Quercetin is a polyphenolic flavonoid with potential chemopreventive activity. Quercetin, ubiquitous in plant food sources and a major bioflavonoid in the human diet, may produce antiproliferative effects resulting from the modulation of either EGFR or estrogen-receptor mediated signal transduction pathways. Although the mechanism of action of action is not fully known, the following effects have been described with this agent in vitro: decreased expression of mutant p53 protein and p21-ras oncogene, induction of cell cycle arrest at the G1 phase and inhibition of heat shock protein synthesis. This compound also demonstrates synergy and reversal of the multidrug resistance phenotype, when combined with chemotherapeutic drugs, in vitro. Quercetin also produces anti-inflammatory and anti-allergy effects mediated through the inhibition of the lipoxygenase and cyclooxygenase pathways, thereby preventing the production of pro-inflammatory mediators. Quercetin is a flavonoid widely distributed in many plants and fruits including red grapes, citrus fruit, tomato, broccoli and other leafy green vegetables, and a number of berries, including raspberries and cranberries. Quercetin itself (aglycone quercetin), as opposed to quercetin glycosides, is not a normal dietary component. Quercitin glycosides are converted to phenolic acids as they pass through the gastrointestinal tract. Quercetin has neither been confirmed scientifically as a specific therapeutic for any condition nor been approved by any regulatory agency. The U.S. Food and Drug Administration has not approved any health claims for quercetin. Nevertheless, the interest in dietary flavonoids has grown after the publication of several epidemiological studies showing an inverse correlation between dietary consumption of flavonols and flavones and reduced incidence and mortality from cardiovascular disease and cancer. In recent years, a large amount of experimental and some clinical data have accumulated regarding the effects of flavonoids on the endothelium under physiological and pathological conditions. The meta-analysis of seven prospective cohort studies concluded that the individuals in the top third of dietary flavonol intake are associated with a reduced risk of mortality from coronary heart disease as compared with those in the bottom third, after adju...
