葉綠素衍生物之光敏抗菌研究

Abstract

結合光敏劑與特定光源產生活性氧分子，應用於抑制微生物生長，乃近年常見的抑菌研發技術。本研究將菠菜葉綠素降解，製備成具光敏性的衍生物。經高效液相層析儀（high performance liquid chromatography; HPLC）分析顯示，衍生物主要成分為脫鎂葉綠素或脫鎂葉綠酸。 The combination of a photosensitizer and a specific light source to generate reactive oxygen species for the inhibition of microbial growth is a developing antibacterial technique. In this study, the chlorophyll of spinach was degraded to prepare photosensitizer chlorophyll derivatives. The results of high performance liquid chromatography (HPLC) analysis showed that the main component was pheophytin or pheophorbide.
