Type: article
Abstract: Objective: Corn cob is a part of plant Zea mays that have a phenolic and flavonoid compounds. This research aims to evaluate total phenolic and flavonoid content, free radical scavenging activity and tyrosinase inhibiton of corn cob (Zea mays) extract. Methods: Corn cob were determined in Poltekkes Kemenkes Surakarta. Meanwhile, corn cob were extracted using maceration method applying 70% ethanol solvent. This extract were analyzed through the total fenolic and flavonoids content tests apply spectrofotometric UV Vis, antioxidant activity using radical scavenging test 2,2-difenill-1-pikrilhidrazil (DPPH) and tyrosinase inhibition test applying in vitro tyrosinase enzyme inhibition. Results: Total phenolic content of the corn cob extract were 1.76 %b/b EAG, while the total of flavonoids content were 0.42%b/b EK. The antioxidant activity using DPPH method test of corn cob extract were values IC50 38.57 µg/ml. Tyrosinase inhibition of corn cob extract were values IC50 919.78µg/ml. Conclusion: Corn cob extract had antioxidant activity and tyrosinase inhibition.
