Turmeric/curcumin are potential agents for wound healing. The therapeutic mechanism of wound healing has been studied by examining the antioxidant effects of curcumin on hydrogen peroxide induced damage to cultured human keratinocytes and fibroblasts (Phan et al 2001).

Curcumin Curcuma longa, a herb belonging to the Zingiberaceous family, is indigenous to India and Southeast Asia. The functional components of this herb, when ground up, are the rhizomes that yield turmeric. Curcumin (3) is a common ingredient in many foods. 

The principal coloring matter in turmeric and its oleoresin is curcumin [458-37-7] (l,6-heptadiene-3,5-dione, l,7-bis[4-hydroxy-3-methoxy-phenyl] (45), an orange-yeUow, crystalline powder, insoluble in water and ether but soluble in ethanol and glacial acetic acid. It has a reported melting point of 180-183°C. 

Curcumin is the main color found in the root of the turmeric plant Curcuma longa, grown in south Asia. 

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. ...

Turmeric contains two main classes of compounds the curcuminoids responsible for the yellow color and the aroma compounds. The coloring principle of turmeric consists of three major phenolic derivatives curcumin, demethoxycurcumin, and bisdemethoxycurcumin. Commercially available products called curcumins contain curcumin (l,7-bis(4-hydroxy-methoxyphenyl)-l,6-heptadiene-3,5-dione) as the major component (about 77% of total curcuminoids). Some other minor phenohc compounds such as cyclocurcumin and calebin were also isolated from turmeric. See Figure 5.2.1. 

The three commercial forms based on Curcuma longa L. are turmeric powder, turmeric oleoresin, and curcumin powder. Turmeric powder is obtained from dried rhizomes. The fresh material is dried under open sun days) or in conventional (fuel, electric) or unconventional driers. Dried rhizomes can be polished to improve... 

Four different commercially available varieties of turmeric containing curcumin were isolated, separated by column chromatography, and identified by spectroscopy. The purity of the curcuminoids was analyzed by an improved HPLC method, performed on a Ci8 column using methanol, acetic acid, and acetonitrile and detection at 425 nm. The total percentages of curcuminoids in turmeric were between 2.34...

Turmeric, also known as curcuma, is an easily fading yellow dye that was used in Mesopotamia many centuries b.c.e. and later became popular in ancient Rome. It is derived from the turmeric plant, Curcuma longa, and other varieties of Curcuma indigenous to China and Southwest Asia. The dye is extracted with hot water from the shredded rhizomes of the plant and then dried into a yellow powder. The coloring matter in turmeric is the organic compound curcumin.
