Most of the diseases begin with an excessive oxidation reaction in the body. The reactivity of free radicals can be inhibited by antioxidant systems. Plants that can be used as an compound antiradical is spinach leaf and the ettuce have a flavonoid compounds that can be used as antioxidant. This study was conducted to determine antiradical DPPH (1,1 diphenyl-2-Picrilhidrazyl) activity of the combination of spinach leaf extract and lettuce extract of in compotition 0: 1, 1: 0, 1: 2, and 2: 1. The methode extraction by maceration with 96% ethanol. The resultsof antiradical DPPH activity test showed that the combination has better than singular. The value of IC50 combination 1: 0 0: 1 1: 2 and 2: 1 are 409,7208 ppm, 297,9908 ppm, 269,7271 ppm, 273,510 ppm, respectively
