Table 6. DPPH radical scavenging activity of hot-water extract from dried persimmon leaves treated with steaming and freezing

Sample¹⁾	DPPH radical scavenging activity (%)
Control	88.45±0.01^b2)
ST	91.82±0.14^a
FT	85.51±0.13^c

Control, non-treated before drying for 12 h at 50°C; ST, treated with steam for 30 sec at 100°C; FT, treated with cold air for 15 days at -20°C. The dried persimmon leaf powder (2 g) was extracted with hot-water (200 mL).
Means±SD (n=3) in a column followed by different superscript letters are significantly different by Duncan’s multiple range test (p<0.05).
