  • In this study, antioxidant activities, proximate composition, and physicochemical characteristics of tetraploid 'Etteum' variety in Platycodon grandiflorum (SD) were evaluated and compared with those of a domestic diploid variety in P. grandiflorum (ND). Moisture content, crude fat, crude fiber, and crude ash contents were higher in ND, whereas crude protein and carbohydrate content were higher in SD. The amount of crude saponin in SD (2.01%) was higher than that in ND (0.88%). The reducing sugar contents of ND and SD were 3.09% and 2.82%, respectively (P<0.05). The pH level was lower in the ND (ND, 4.98; SD, 5.68). Acidity was 2.74% in ND and 2.34% in SD. Under the Hunter color system, redness was lower and lightness/yellowness higher in SD compared to those in ND. Total phenol contents of ND and SD were 0.100 mg/mL and 0.227 mg/mL, respectively. Antioxidant activities based on 1,1-diphenyl-2-picrylhydrazyl scavenging activity and SOD-like activity of SD were higher than those in ND. Based on these results, SD is a good candidate for food processing in terms of its physicochemical and antioxidative activities.
