. AbstractsThis research is to study the antioxidant activity of Canna By screening from Canna Canna 10 type is GISC 2 GISC 6 GISC, 22 for wanwisa Rangsit, sky every way. Waraporn10 g extracted with methanol ratio 1:5 period 5 days and filter, tested the ability to resist free radicals 3 methods. Methods, DPPH assay ABTS assay,FRAP assay and quantitative analysis of polyphenols with Folin-Ciocaltue method showed that the Canna varieties have the ability to resist free radicals by the best. The Canna varieties by 1000 g. Soaked in methanol ratio 1:5 period 5 days. Filter and volatile solvent by distillation rotary evaporation, crude extract all 39.201g (3%) used to separate pure crude extract. Technique of chromatography a thickness (PTLC) with the mobile phase is 20% ethyl acetate in hexane And pure happened 4 position Rf was 0.156 (A1), 0.281 (A2), 0.563 (A3) and 0.656 (A4), respectively. The ethanol extract 4 type. To test the ability of antioxidant and 4 methods, DPPH assay ABTS assay FRAP assay, and determination of พอลิฟีน digital found pure species. A2 have antimicrobial activities A1 more pure, free radicalsA3 A4 by A2 EC50 equal value and 0.896 ppm (TEAC was 1 224.2 mg, Trolox / g extract) were FRAP value was 2.021 mmol. / g extract and were compared with standard compounds polyphenol Gaelic (GAE) was 35.267 mg / g extract when the pure natural A2 to test group introduction. Used for measuring machine with double - wisitsri UV spectrophotometer and ฟูริเออร์ Fourier transform infrared spectrometer, it is found that the substance is A2 substances saponin
