Curcuminoids are bioactive compounds found in turmeric, primarily in the rhizome of the Curcuma longa plant. The most well-known curcuminoid is **curcumin**, but there are others, such as demethoxycurcumin and bisdemethoxycurcumin. These compounds are responsible for turmeric's vibrant yellow color and are recognized for their potential health benefits.
