<![CDATA[Antioxidant is very important to give protection against free radical activity and highlyreactive molecules that could lead in slowing the progression of degenerative disease.In case of degenerative disease, internal antioxidant cannot neutralize the increasingconcentration of free radical. Because of that, human needs external antioxidant.Kersen (Muntingia calabura L.) is a plant that is known for its antioxidant content.Plants containing antioxidant experience is kersen (Muntingia calabura L.). Researchstudy to determine the antioxidant activity of Kersen plant and knows the differenceof antioxidant activity, based on the process of extract and infusion. Research wasdone by experimental study which was oriented in testing antioxidant activity in(Morinda citrifolia L.) extract and infusion. Extraction was done by using 96% ethanolas solvent, meanwhile infusion was made by using aquadest. Extract and infusionwas divided into group of concentration and antioxidant activity was tested byDPPH(2,2-Diphenyl-1-Picrylhidrazyl) method by measuring the absorbance usingspectrophotometer at 520 nm wavelength. Percentage of DPPH inhibition and IC50then analyzed using linear regression analysis. Ethanolic extract of kersen leaf andepiphyte had IC50 value of 113,801 ppm and 98,7802 ppm, respectively. Kersen leafinfusion showed 191,7624 ppm IC50 values, besides its epiphyte had 131,6750 ppm.Antioxidant activity of Muntingia calabura L. in the order from kersen leaf anepiphyte, and epiphyte extract has a higher antioxidant content than others.]]>
