Bisdemethoxycurcumin is a curcuminoid found (along with the curcuminoids curcumin and demethoxycurcumin) in turmeric (Curcuma longa), but absent in Javanese turmeric (Curcuma xanthorrhiza).[1] Bisdemethoxycurcumin is used as a pigment and nutraceutical with antimutagenic properties.[2][3] All three of the curcuminoids found in Curcuma longa have been shown to have antioxidant properties, but bisdemethoxycurcumin is more resistant than the others to alkaline degradation.[4] It was found to be effective in sensitizing PC cells resistance against gemcitabine.[5]
