영문 초록

To obtain the information on various physiological activities in Camellia sinensis L., we investigated antioxidant, antimicrobial and anticancer activities using methanol extracts of leaf, stem, ovary, seed and flower. Total phenolic compound and flavonoid contents were the highest in leaf and followed by stem, flower, ovary, and seed. As RC50 value, that was, the concentration of sample required for 50% reduction of 2,2-diphenyl-1-picrylhydrazyl (DPPH) free radical, was 2.5-5.4 μg/mL in leaf, stem, ovary and flower. C. sinensis had antimicrobial activities against six strains such as Bacillus subtilis, Bacillus cereus, Staphylococcus aureus, Citrobacter freundii, Candida albicans,and Saccharomyces cerevisiae by different harvesting parts. Especially, flower had a very high antimicrobial activity against S. aureus. All harvesting parts of C. sinensis had anticancer activities with high growth inhibition rates of AGS (stomach cancer cell), HELA (cervix cancer cell), HT-29 (colon cancer cell), and MCF-7 (breast cancer cell).
