Bisdemethoxycurcumin is a polyphenolic curcuminoid pigment present in turmeric rhizomes (Curcuma longa) alongside curcumin and demethoxycurcumin. It features two 4-hydroxyphenyl groups linked by a heptadiene-dione chain and lacks the methoxy substituents found in curcumin. This structural difference influences its antioxidant potency, anti-inflammatory activity, and bioavailability. Research indicates potential roles in modulating NF-κB pathways, reducing oxidative stress, and exhibiting antiproliferative effects in cancer cell lines. It contributes to the yellow color of turmeric and is studied for nutraceutical applications, though it shows lower bioavailability than curcumin. The compound is extracted using organic solvents and is stable under acidic conditions but degrades in alkaline environments.
