ABSTRACT
The family of Zingiberaceae, including the genus Curcuma, has been used since hundreds of years ago as ingredient of traditional medicines. Various scientific studies to support its use as traditional medicine was already done. One of the most prominent biological activity possessed by the family of Zingiberaceae was the antioxidant activity. The aim of this research was to examined the antioxidant activity and flavonoid content of rhizome’s extract of Curcuma heyneana, Curcuma mangga, Curcuma aeruginosa, Curcuma phaeocaulis and Curcuma purpurascens. The antioxidant activity was determined by DPPH method and total flavonoid content was determined by colorimetric method. The antioxidant activity of Curcuma rhizome’s extract in this study ranged from very strong to weak. C. purpurascens had a very strong antioxidant activity (EC50 value of 36.30 ppm) and also the highest flavonoids content measured as quercetin (14.27%). Based on correlation analysis (R2 = 0,6573), there is a positive correlation between total flavonoid content with antioxidant activity of the extract.
