  • In this study, the anticancer activity of the water extract at $100^{\circ}C$ was compared to that of the callus extracts via a ultrasonification extraction process. All the extracts were utilized to evaluate cytotoxicity, antioxidant and immune activities. The callus extracted via ultrasonification extraction showed relatively low cytotoxicity on normal human cell lines, HEK293 and HEL299, showing 13.17% and 21.78%, respectively. The callus extract has 59.82% which was similar to 61.70% for water extracts. It was also found that callus extract yielded higher nitric oxide secretion form macrophage than other extracts. The growths of both human stomach adenocarcinoma (AGS) cell and human lung carcinoma (A549) were inhibited up to 70% by adding 1.0 mg/mL of the callus extracts with ultrasonification extraction. This inhibition ratio (70%) was almost close to that of water extract. Human hepatoma carcinoma (HEP3B) cell growth was most significantly inhibited up to 75% by adding 1.0 mg/mL of callus extracts, and its selectivity was highest compared to other extracts. It indicates that the callus extracts could selectively inhibit growth of digestive system-related cancer cells. It can be also concluded from the results of this study that the callus extracts associated with ultrasonification extraction process have the potential for anticancer activity.

  • Shelf-life of brined baechu cabbage was extended by pasteurization at $65^{\circ}C$ for 30 min. Starters (Leu. citreum and Lab. plantarum) were added to the pasteurized brined cabbage to supply beneficial lactic acid bacteria during kimchi fermentation. Control kimchis made with baechu cabbage without pasteurization and no addition of the starters to the pasteurized cabbage kimchi were also prepared. The fermentation characteristics and health functionalities of DPPH free radical scavenging activities and in vitro anticancer effects in AGS human gastric cancer cells were compared. The pasteurized brined cabbage could not be fermented well and the functionalities were also low; however, the addition of starter(s), especially mixed starters of Leu. citreum and Lab. plantarum to the pasteurized brined cabbage, significantly increased the counts of lactic acid bacteria, hardness (texture) and overall acceptability in sensory evaluation. The free radical scavenging activities and the anticancer effects were also increased. The fermentation patterns of starter added kimchi prepared with pasteurized brined cabbage were similar to those of naturally fermented kimchi. It seemed that growth of lactic acid bacteria during kimchi fermentation contributed to increased taste and health functionality of kimchi.

  • This study was carried out to find the preventive medical and therapeutic effects of Sarcodon asparatus on adult disease by employing several biological and biochemical assays. Nitrate scavenging ability(NSA) of Sarcodan asparatus extracts was displayed up to 99.9% at pH 1.2 in a dose-dependent manner. They also had 90.4% electron donating ability(EDA) at the concentration of 0.1 mg/mL. Extracts of Sarcodon asparatus were also able to function as a powerful antioxidant at all concentrations(0.01∼l.0 mg/mL). Furthermore, we observed that 1 mg/mL concentration of the extracts was more powerful than BHT, With respect to fibrolytic activity, Sarcodon asparatus showed 1,843.8 unit/g, which was higher than streptokinase(1,189 unit/g). The inhibitory effects of the extracts on angiotensin converting enzyme, measured by the normal and pretreatment methods, were 53 and 58%, respectively. We also performed cytotoxicity effect of Sarcodon asparatus extracts on a various cancer cell lines. The growth inhibitory effects of the extracts(5.0 mg/mL) on A549, HeLa, AGS, and SK-Hep-1 cells were 78.9, 55.3, 69.0, and 42.5 %, respectively. Interestingly, Sarcodon asparatusextracts induced mutation on Salmonella typhimurium TA98 and TA100 when Ames test was done.
