AKTIVITAS ANTIOKSIDAN DARI EKSTRAK TONGKOL JAGUNG (Zea mays L.)

Abstract

The objective of this research was to determine the potential antioxidant phytochemical
extracts corn cob (Zea mays L.). Corn cobs extracted using maceration method for 1x24 hours.
Determination of phytochemical content is done by calculating the total phenolic. Testing
antioxidant activity using free-radical scavengers DPPH (1,1-diphenyl-2-pikrilhidrazil). Results of
this research showed that the extract of corn cobs have total phenolic. Extract 60% corn cobs have
prophylactic activity of free radicals, followed by extract 40, 80 and 20%. Conclusion of this
