This study was conducted to investigate antioxidant activity and functional component analysis in different sections of Korean mountain ginseng (seed, leaf, stem and root). The major free amino acids were arginine, proline, $\gamma-amino-n-butyric$ acid, alanine and aspartic acid, and proline showed the highest content 22.98 mg/g in 80% MeOH extract of seed. Contents of $\gamma-amino-n-butyric$ acid and alanine were the highest in 80% MeOH extract of leaf, with 26.04 mg/g and 13.07 mg/g. Aspartic acid showed the highest content 23.42 mg/g in 80% MeOH extract of leaf. The major fatty acids were identified as palmitic acid, oleic acid and linoleic acid by GC. Content of total phenolic compounds were 737 mg% in 80% EtOH extract of seed, and 560 mg% in 80% MeOH extract of seed. The highest contents of ferulic acid and salicylic acid were $875{\mu}g/g\;and\;78{\mu}g/g$ in 80% MeOH extract of leaf, and $\rho-coumaric$ acid was $181{\mu}g/g$ in 80% MeOH extract of stem, respectively. The highest contents of ginsenoside-Rg1, Re, Rd and Rc were $14.5{\mu}g/g,\;48.78{\mu}g/g,\;27.57{\mu}g/g\;and\;4.87{\mu}g/g$ in 80% MeOH extract of leaf, respectively. Antioxidant activities by DPPH were 83.82% in water extract of leaf, 89.74% in 80% EtOH extract of leaf and 88.37% in 80% MeOH extract of leaf, and 92.81% in BHA (200 ppm). These results suggest that Korean mountain ginseng is very important as functional food material.
