토종 복분자 Rubus coreanus와 외래종 복분자 Rubus occidentalis 추출물의 항산화능 비교

摘要: This study compared the antioxidant effects of two kinds black raspberry extract, obtained from fruits Rubus coreanus and occidentalis, which can be found in Korea. The R. occidentalis were each extracted with 0%, 25%, 50%, 75%, 100% ethanol (EtOH). Among extracts these varieties, 50% EtOH extract showed highest contents total polyphenols (46.96±2.78 mg/g) flavonoid compounds (11.77±0.81 mg/g). activity (84.77±0.97%) terms DPPH radical scavenging activity. On contrary, 25% best (29.65±2.41%) ABTS In results ferric reducing power (FRAP) assay, (0.49±0.02%). cytotoxicity test stimulated H2O2, 75% cell viability (93.54±3.37% 97.19±0.74%, respectively). According to our results, higher activities than coreanus. Especially, polyphenol significant correlation FRAP by Pearson's (P=0.005 P=0.013,
