It is now agreed that food plays a major role in the maintenance of good health. The awareness of consumers about diet‐related health problems has increased. Hence, nowadays, preference is given to the natural food ingredients, which are expected to be safe and health promoting. Recently, many studies on health benefits associated with curcumin have been reported. In the present study, an attempt had been made to isolate curcumin from a mixture of curcuminoids by means of column chromatography technique. Further, the antioxidant activity of curcumin was studied in refined sunflower oil (RSFO). The activity was compared with that of mixture of curcuminoids in RSFO. The results showed that the other curcuminoids, i.e., demethoxycurcumin and bisdemethoxycurcumin had a profound effect on the activity of curcumin. Practical Applications Natural extracts have potential to stabilize unsaturated essential fatty acids effectively. It is well known that the presence of an active constituent in these natural extracts provides the property of antioxidant to the extract. The results revealed that the minor constituents had a profound effect on the activity of active constituent. The synergistic activity of all the constituents in an extract determines the resultant antioxidant activity of the extract.

“…As discussed in our previous study, curcuminoids showed pro-oxidant effect in refined sunflower oil [26] due to absence of free fatty acids. The behaviour of curcuminoids in presence of lecithin in RSFO was evaluated.…”

“…In the view of the importance of curcumin, the objective of the study was to evaluate the activity of curcuminoids in crude and refined sunflower oil containing tertiary butylhydroquinone (TBHQ). The synergistic activity of curcuminoids with other natural antioxidants is illustrated [26,27]. However, curcuminoids do not show remarkable synergistic effect in the presence of lipophobic antioxidant like ascorbic acid in water-in-oil emulsion [28].…”
