Pigments curcumin

A series of natural and synthetic products have also shown antiamyloid properties as amyloid scavengers or P-breakers. One example is the phenolic yellow curry pigment curcumin, which has potent anti-inflammatory and antioxidant activities and can suppress oxidative damage, inflammation, cognitive deficits, and amyloid... 

Sesquiterpenes ketone (65% e.g. turmerone), zingiberene (about 25%), pliellandrenc, sabinene, borneol and cineole 3%-4% pigments curcumin, monodemethoxy curcumin, bi.sdemethoxycurcumin, di-p-ccmmaioylmethane... 

The purpose of this chapter is to provide an overview of our present knowledge about the health benehts of pigments, particularly their effects on chronic diseases. We examine the effects of lipophilic (carotenoids, chlorophylls) and hydrophilic pigments (anthocyanins and flavones-flavonols), and curcumin. Descriptive and mechanistic studies are reviewed in regard to common chronic diseases. 

Curcumin (diferuloyl methane) is the main pigment of turmeric. It is widely used as a colorant and preservative agent. No data regarding its daily intake in western countries are available intake may reach 80 to 200 mg in adult Indians. To date, no study has explored the effect of curcumin consumption on the incidence of diseases, but many beneficial effects on health have been reported in cell and animal models. These include anti-carcinogenic, anti-diabetic, anti-atherosclerotic, and anti-Alzheimer s disease properties. ... 

Stable dispersion of water-insoluble and/or hydrophobic natural pigment such as carotenoid, curcumin, porphyrin pigment, or vegetable carbon black in form of bodies of average size of 10 ram Addition of 0.5 ppm P-carotene to yogurt containing 200 ppm riboflavin color did not change after 40 days at 6°C compared with control (decoloration at 1 day)... 

Curcumin is a bright yellow pigment that is oil soluble. It is sometimes produced in a water dispersible form.

The colour pigment of turmeric is curcumin. Curcumin is relatively polar and almost unsoluble in C02 at extraction pressures below 400 bar. At pressures higher than 500 bar a yellow mixture of oil and cristalline curcumin can be obtained. The extraction yield varies between 5 and 12% depending on raw material. 

Curcumin is obtained from the spice turmeric which comes from the plant Curcuma longa, which itself is related to ginger. Curcumin is a bright yellow pigment which is obtained by extraction from the plant to give a deodorised product. It is oil soluble but is sometimes produced in a water dispersible form. 

One example that can demonstrate the effectiveness and great promise of nanoencapsulation is the curcumin nanoemulsions. Curcumin is the major yellow pigment in turmeric Curcuma longa Linn). In South and Southeast Asia, curcumin preparation or turmeric has been used extensively to treat inflammatory conditions and chronic diseases (Reddy and Rao 2003). Orally administered curcumin usually has low systemic bioavailability. Only trace amounts of curcumin (or its metabolites) appear in the blood, and most of ingested curcumin is excreted in the feces. One reason is that curcumin has low solubility and does not disperse for absorption. The absorbed curcumin is rapidly metabolized in the intestine and liver to several reduction products (di-, tetra-, and hexa-hydrocurcumin and hexahydrocurcuminol) and... 

Curcumin, a yellow pigment isolated from turmeric, and cystic fibrosis (Opener, Problem 17.52)... 

The major pigment in Curcuma species (Zingiberaceae family) is the yellow phenolic diarylheptanoid curcumin (Jl). Curcumin and its analogs have potent antioxidant and antiinflammatory effects, cytotoxicity against tumor cells, and antitumor-promoting activity (96). The biologic effects and targets of curcumin, as well as its possible roles in cancer prevention and therapy, have been reviewed recently (97, 98). 

Turmeric or curcumin is the fluorescent-yellow-colored extract from the rhizome of various species of curcuma plant, Curcuma longa L. The main pigment of curcuma is curcumin (Formula 9.18).
