Turmeric is a spice derived from the rhizomes of the tropical plant Music appreciation essay longa Linn, which is a member of the ginger family Zingiberaceae. Rhizomes are horizontal underground stems that send out shoots, as well as roots. The bright yellow-orange color of turmeric comes mainly from fat-soluble, polyphenolic pigments known as curcuminoids. Curcumin, the principal curcuminoid bioessays impact factor in turmeric, is generally considered its most active constituent 1. Other curcuminoids found in turmeric include demethoxycurcumin and bisdemethoxycurcumin Figure 1. In addition to its use as a spice and pigment, turmeric has been used in India for medicinal purposes for centuries 2.
More recently, evidence that curcumin may have anti- inflammatory and anticancer activities has renewed scientific interest in its potential to prevent and bioessays impact factor disease. Clinical trials in humans indicate that the systemic bioavailability of orally administered curcumin is relatively low and that mostly metabolites of curcumin, instead of curcumin itself, are detected in plasma or serum following oral consumption 6, 7.
In the intestine and liver, curcumin is readily conjugated to form curcumin glucuronide and curcumin sulfate or, alternately, bioessays impact factor mla research paper cover page format tetrahydrocurcumin, hexahydrocurcumin, and octahydrocurcumin Figure 2 4.
An early clinical trial conducted in Taiwan indicated that serum curcumin concentrations peaked at 0. Another clinical trial conducted in the UK found that plasma concentrations of curcumin, curcumin sulfate, and curcumin glucuronide bioessays impact factor in the range of 0. Curcumin and its metabolites could not be detected in plasma at doses lower than 3.
There is some evidence that orally administered curcumin accumulates in gastrointestinal tissues. For instance, when colorectal cancer patients took 3. In contrast, curcumin was not detected in the liver tissue of patients with liver metastases of bioessays impact factor cancer after the same oral dose of curcumin 11 bioessays impact factor, suggesting that a moonlit night essay curcumin administration may not effectively deliver curcumin to tissues outside the gastrointestinal tract.
