Dried leaves of Raphanus sativus L. and Angelica keiskei L. extracts have strong antioxidant potential and in consequence profound effects on ulcerative colitis. Present study was conducted to explore the effect of diet mixtures containing dried leaves of Raphanus sativus and Angelica keiskei powder on ulcerative colitis in mice and antioxidant potential of radish green and Angelica extracts as well. Both dried leaves of Raphanus sativus and Angelica keiskei extracts exhibited higher antioxidant activity due to the presence of polyphenols, favonoids and antioxidant enzymes like superoxide dismutase (SOD). Analyzed data indicate that Angelica keiskei extract had higher polyphenol and flavonoid contents compared with radish green, while maximum SOD activity was noted in dried leaves of Raphanus sativus extract Likewise, higher antioxidant (348.72 ± 31.65 μg/mL) and ABTS+ radical scavenging (17%) activities were noted in dried leaves of Raphanus sativus extract compared with Angelica keiskei.
