Abstract

Extracts of Curcuma domestica Val. in Extra Virgin Olive Oil and Virgin Coconut Oil is an herbal oil that has potential as herbal medicines. The extraction method used was hot maceration. The antioxidant activity test parameter uses the DPPH method and the identified functional groups using FTIR spectrophotometer. Total phenol levels were tested using Folin-Ciocalteu reagent. Turmeric extract with EVOO at a concentration of 40% had the highest antioxidant activity value with an EC50 of 1220 ppm, meanwhile turmeric extract with VCO at a concentration of 30% had the highest antioxidant activity value with an EC50 of 487 ppm. The FTIR test showed the presence of functional groups O-H, C=O, C=C, and C-H which are typical functional groups in curcumin. The highest total phenol content of turmeric extract in EVOO was obtained at a dose concentration of 40%, extraction temperature of 70°C and extraction time of 6 hours with a value of 7.48% GAE. Meanwhile, the highest total phenol content of turmeric extract in VCO was obtained at a concentration of 40%, extraction temperature of 70°C and extraction time of 4 hours with a value of 11.4% GAE.
