activity, nitrite scavenging activity, superoxide dismutase like activity of the radish leaves (Raphanus sativus
L.) extracts. Radish leaves extracts were prepared using water extraction, 50% ethanol extraction and 50%
methanol extraction. The yield of Kwandong radish leaves extracts without blanching treatment (DRLK) was
26.56∼32.56% and the extract yield of Minongdanbaek radish leaves without blanching treatment (DRLM)
was 34.34∼36.90%. On the other hand, the yield of samples with blanching treatment was a lower range value
of 18.70∼23.56% than samples without blanching treatment. In the total contents of phenolic compound, samples
with and without blanching treatment were 49.1∼59.4 mg/g and 53.41∼62.08 mg/g, respectively. Minongdanbaek
radish leaves extracts (DRLM, BDRLM) showed higher contents value than Kwandong radish leaves extracts
(DRLK, BDRLK) in the total phenolic compounds. Samples without blanching treatment showed electron donating
activity above 80%, nitrite scavenging activity of 36.63～51.17% and superoxide dismutase like activity
of 38.53～45.38%. Generally, Kwandong samples showed a little higher activity more than Minongdanbaek samples
in the electron donating activity, nitrite scavenging activity and superoxide dismutase like activity. Also,
radish leaves extracts without blanching treatment showed high physiological activities.
