Abstract
4-year-old fresh ginseng was stored for 12 weeks at 4$^{\circ}C$ under the CA storage and samples were withdrawn after every 1, 2, 3, 4, 6, 8 and 12 weeks for processing of red ginseng. Antloxidative and cytotoxic activities of steamed red ginseng for the quality evaluation are summarized as follows: Reducible activity of water extract to 1, 1-dipenyl-2-picryl hydrazyl increased with increasing storage period. Antioxldative activity of red ginseng did not change in petroleum ether fraction, while it had a tendency to increase In the fractions of ethyl ether and ethyl acetate with increasing storage period. in contrast to fresh ginseng, malonaldehyde formation In heparin mlcrosome of red ginseng processed from fresh ginseng stored In CO2:O2:Nl (6:4:90) with a 0.5% DF-100 immersion condition decreased but was not changed significantly by the period of storage. Cytotoxic activity against cancer cell at a 40 mg/ml concentration of red ginseng slightly increased with an increase in storage period but no effect was observed at the concentration less than 10 mg/ml.
