Coconut oil enriched with phenolic compounds from some curcuma species can be used in cosmetic products or food supplement. The objectives of this work were to produce coconut oil incorporated with some extract of curcuma species including Curcuma aromatica Salisb, Curcuma longa L., Curcuma xanthorrhiza Roxb., Curcuma Zediaria Roscoe, Cucuma aeruginosa Roxb, Curcuma aurantiaca Van Zijip., and Cucuma parviflora Wall H., and to determine the antioxidant activity and the total phenolic content of the coconut oil obtained. The antioxidant activity of resulting coconut oil was assayed with DPPH (2,2-diphenyl-1-prohydrozyl), and ABTS. Antioxidant activity with ABTS and DPPH calculated in IC50 (the concentration of an antioxidant at with 50% inhibition of free radical activity), IC50 values at 30 min was found in the range of 0.35 to 13.58 mg/ml and 2.66 to 179.40 for ABTS and DPPH, respectively. The results showed that the coconut oil with extracted Curcuma Zediaria Roscoe had the highest antioxidant activity calculated in IC50, 0.35 mg/ml and 2.66 for ABTS and DPPH radical scavenging assay, respectively. Based on the Folin-Ciocalteu method, the total phenolic content was found in the range of 2.95 to 132.42 mg/g oil. Coconut oil with extracted Curcuma Zediaria Roscoe had the highest total phenolic content (132.42 mg/g oil) among other species.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
