The objective of this study is to evaluation the total polyphenol and the antioxidant activity of freeze‐dried ginseng( Panax genseng C.A. meyer cv Yun‐poong) for root area and diameter. Ginseng root consists of the main root(MR), lateral root(LR) and fine root(FR). These roots were sorted 3~4 group(MR 1~4 group, LR 1~4 group, FR 1~3 group) depending on the diameter of each center region. Total polyphenol content of ginseng showed the highest in FR‐3 among the all samples. The antioxidant activity measured using DPPH radical‐scavenging activity and ABTS radical scavenging activity. DPPH radical‐scavenging activity of FR‐3(IC 50 : 7.03 mg/mL) showed the highest value in all samples but MR‐2(IC 50 : 37.02 mg/mL) showed the lowest value. On the whole, hydrogen donating activity of FR was significantly higher than for other groups. ABTS radical scavenging activity of FR‐3 was significantly higher than any of the other samples. Polyphenol content and antioxidant activity of ginseng showed the highest in FR‐3 and the result exhibited that polyphenol content and antioxidant activity of ginseng were related to root area and diameter.
