Curcumin: Structural Characteristics
Classification of Active Compounds in Turmeric
The active compounds in turmeric are typically classified as non-volatile or volatile compounds:
The rhizomes of turmeric abound in many phenolic compounds known as Curcuminoids —responsible for the yellow colour.
It is comprised of Curcumin (75–81%), Demethoxycurcumin (15–19%) and Bisdemethoxycurcumin (2.5–6.5%).
Most of commercial Curcuminoids sold as “Curcumin”, are mixtures of the three Curcuminoids. Curcumin C3 Complex®, the branded composition of natural Curcuminoids, pioneered and patented by Sabinsa Corporation, is a well characterized composition. The Curcumin C3 Complex® is standardized to contain ≥95% Curcuminoids by HPLC analysis and is currently being used by several clinical researchers with Investigational New Drug (IND) approval from the USFDA and other regulatory organizations overseas.
