Transcript of "The Antibacterial Effect of Tea - YukiAraie"

  1. 1. The Antibacterial Effect of Tea Faculty of Pharmaceutical Sciences freshman Yuki Araie
  2. 2. Outline• Introduction• Materials and methods• Results• Discussion• Conclusion
  3. 3. Introduction Tea – world wide beveragePurpose• What kind of tea is effective? • Green tea• How’s the effect of blended tea? • Average of all
  4. 4. Materials• Tea Blend • Oxidation • Fermentation Green Oolong Black Pu’er • Blended all• Bacteria • 8 species from researchers’ body surface
  5. 5. Methods Incompletely inhibited• Agar culture medium + tea extracts (1%, 4%, 10%, 25%)• Bacteria were attached on the same lines. Agar medium• Incubated at 37℃ for a day.• Bacterial growths were examined with the eye. Completely inhibited
  6. 6. Results ↑ 0% ↑ Green tea 4% ↑ Green tea 10% ↑ Green tea 25%
  7. 7. Graph: the antibacterial effect of teaThe number of species of bacteria 8 7 6 5 4 3 2 25% 1 10% 0 4% Blended 1% Green Oolong Black Puer Heights: The number of species of bacteria which were completely inhibited their growth by tea.
  8. 8. Graph: the antibacterial effect of teaThe number of species of bacteria 8 7 6 5 4 3 2 25% 1 10% 0 4% Blended 1% Green Oolong Black Puer Heights: The number of species of bacteria which were completely inhibited their growth by tea.
  9. 9. Graph: the antibacterial effect of teaThe number of species of bacteria 8 7 6 5 4 3 2 25% 1 10% 0 4% Blended 1% Green Oolong Black Puer Heights: The number of species of bacteria which were completely inhibited their growth by tea.

  13. 13. Discussion The Antibacterial Effect of Tea Blended ≒ Green ≒ Oolong > Black > Pu’er damage the effect Oxidative FermentationBlended Green Oolong Black Pu’er
  14. 14. Conclusion Oxidative fermentation damages the antibacterial effect of tea. For future studies: The effect of tea in vivo. ex. Tea intake as a treatment of disease. a prevention of cold.
