The aim of this study was to investigate functional food material for the antioxidant and biological activities of untreated and steam-treated Corni fructus extracts in extraction solvents (through hot-water extraction, 50% ethanol extraction, and 50% methanol extraction). The yield of UCH (hot-water extract of untreated Corni fructus) was 47.45% and it was higher than those of extracts (13.20-27.18%) obtained by the other extraction methods. The total phenolic and flavonoid contents were 12.23 g/100 g (SCE, 50% ethanol extract of steam-treated Corni fructus) and 5.08 g/100 g (SCE), respectively, and the total sugar content was 71.32 g/100 g (SCH, hot-water extract of steam-treated Corni fructus). The main organic acid components of the extracts were oxalic acid, citric acid, malic acid, formic acid, and gallic acid. The DPPH and ABTS radical scavenging activities of SCE at 1,000 μg/mL were 72.37% and 43.15%, respectively. The ferric-reducing antioxidant power of SCE at 1,000 μg/mL was 689.49 μM. The extracts were investigated for their function in L-132, RAW 264.7, HeLa, and MCF-7 cell lines. The SCE performed better than the other extracts in terms of its protective effects against oxidative stress in L-132 cells and increased the production of NO. Further the SCE showed antitumor activities against HeLa and MCF-7 cancer cells. Therefore, the SCE extracts is a good functional food material for the prevention of woman disease. Therefore, in our study, the SCE extracts is good functional food material for the prevention of oxidant, immunological, and tumor related disease.
