Improved HPLC Method for the Determination of Curcumin, Demethoxycurcumin, and Bisdemethoxycurcumin
Journal of Agricultural and Food Chemistry, 2002Commercially available curcumin, a bright orange-yellow color pigment of turmeric, consists of a mixture of three curcuminoids, namely, curcumin, demethoxycurcumin, and bisdemethoxycurcumin. These were isolated by column chromatography and identified by spectroscopic studies. The purity of the curcuminoids was analyzed by an improved HPLC method.

Demethoxycurcumin: A naturally occurring curcumin analogue for treating non‐cancerous diseases
Journal of Cellular Physiology, 2019AbstractTurmeric extracts contain three primary compounds, which are commonly referred to as curcuminoids. They are curcumin, demethoxycurcumin (DMC), and bisdemethoxycurcumin. While curcumin has been the most extensively studied of the curcuminoids, it suffers from low overall oral bioavailability due to extremely low absorption as a result of low ...

Demethoxycurcumin suppresses HK2-mediated glycolysis by targeting PTEN/Akt signaling
Cancer Gene TherapyAerobic glycolysis is a hallmark of tumor cells, with the expression of glycolytic enzymes often being upregulated in many cancers, leading to enhanced metabolic activity. Among the key rate-limiting enzymes in this process, Hexokinase 2 (HK2) plays a crucial role in sustaining the biological activities of human cancers.
