Bis-desmethoxycurcumin
Bisdemethoxycurcumin is a curcuminoid found (along with the curcuminoids curcumin and demethoxycurcumin) in turmeric (''Curcuma longa''), but absent in Javanese turmeric (''Curcuma xanthorrhiza''). Bisdemethoxycurcumin is used as a pigment and nutraceutical with antimutagenic properties. All three of the curcuminoids found in Curcuma longa have been shown to have antioxidant properties, but bisdemethoxycurcumin is more resistant than the others to alkaline degradation. It was found to be effective in sensitizing PC cells resistance against gemcitabine. See also * Curcumin * Desmethoxycurcumin Desmethoxycurcumin is a curcuminoid found in turmeric.

Curcuminoid
A curcuminoid is a linear diarylheptanoid, a relatively small class of plant secondary metabolites that includes curcumin, demethoxycurcumin, and bisdemethoxycurcumin, all isolated from turmeric (Turmeric, curcuma longa). These Chemical compound, compounds are natural phenols and produce a pronounced yellow color that is often used to color foods and medicines. Curcumin is obtained from the Rhizome, root of turmeric. Curcuminoids are solubility, soluble in dimethyl sulfoxide (DMSO), acetone and ethanol, but are poorly soluble in lipids. It is possible to increase curcuminoid solubility in water, aqueous phase (matter), phase with surfactants or surfactant, co-surfactants. Most common derivatives have different substituents on the phenyl groups. There is an increasing demand for demethoxycurcumin, bisdemethoxycurcumin, and other curcuminoids because of their biological activity. Cyclodextrins Curcuminoids form a more stable Coordination complex, complex with solutions which c ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Turmeric
Turmeric () is a flowering plant, ''Curcuma longa'' (), of the ginger family, Zingiberaceae, the rhizomes of which are used in cooking. The plant is a perennial, rhizomatous, herbaceous plant native to the Indian subcontinent and Southeast Asia that requires temperatures between and a considerable amount of Annual rainfall in india, annual rainfall to thrive. Plants are gathered each year for their rhizomes, some for propagation in the following season and some for consumption. The rhizomes are used fresh or boiled in water and dried, after which they are ground into a deep orange-yellow powder commonly used as a food coloring#Natural food dyes, coloring and flavoring agent in many Asian cuisines, especially for Curry, curries, as well as for dyeing, characteristics imparted by the principal turmeric constituent, curcumin. Turmeric powder has a warm, bitter, black pepper-like flavor and earthy, mustard plant, mustard-like aroma. Curcumin, a bright yellow chemical produced by ...

Curcumin
Curcumin is a bright yellow chemical produced by plants of the ''Curcuma longa'' species. It is the principal curcuminoid of turmeric (''Curcuma longa''), a member of the ginger family, Zingiberaceae. It is sold as a herbal supplement, cosmetics ingredient, food flavoring, and food coloring. Chemically, curcumin is a diarylheptanoid, belonging to the group of curcuminoids, which are natural phenol, phenolic pigments responsible for the yellow color of turmeric. Laboratory and clinical research have not confirmed any medical use for curcumin. It is difficult to study because it is both unstable and poorly bioavailable. It is unlikely to produce useful leads for drug development. History Curcumin was named in 1815 when Henri Auguste Vogel and Pierre Joseph Pelletier reported the first isolation of a "yellow coloring-matter" from the rhizomes of turmeric. Later, it was found to be a mixture of resin and turmeric oil. In 1910, Milobedzka and Lampe reported the chemical structure ...

Food Colorings
Food coloring, or color additive, is any dye, pigment, or substance that imparts color when it is added to food or drink. They come in many forms consisting of liquids, powders, gels, and pastes. Food coloring is used in both commercial food production and domestic cooking. Food colorants are also used in a variety of non-food applications, including cosmetics, pharmaceuticals, home craft projects, and medical devices. Purpose of food coloring People associate certain colors with certain flavors, and the color of food can influence the perceived flavor in anything from candy to wine. Sometimes, the aim is to simulate a color that is perceived by the consumer as natural, such as adding red coloring to glacé cherries (which would otherwise be beige), but sometimes it is for effect, like the green ketchup that Heinz launched in 2000. Color additives are used in foods for many reasons including: * To make food more attractive, appealing, appetizing, and informative * Offset col ...

Phenol Antioxidants
Phenol (also called carbolic acid) is an aromatic organic compound with the molecular formula . It is a white crystalline solid that is volatile. The molecule consists of a phenyl group () bonded to a hydroxy group (). Mildly acidic, it requires careful handling because it can cause chemical burns. Phenol was first extracted from coal tar, but today is produced on a large scale (about 7 billion kg/year) from petroleum-derived feedstocks. It is an important industrial commodity as a precursor to many materials and useful compounds. It is primarily used to synthesize plastics and related materials. Phenol and its chemical derivatives are essential for production of polycarbonates, epoxies, Bakelite, nylon, detergents, herbicides such as phenoxy herbicides, and numerous pharmaceutical drugs. Properties Phenol is an organic compound appreciably soluble in water, with about 84.2 g dissolving in 1000 mL (0.895 M). Homogeneous mixtures of phenol and water at phenol to wate ...
