概要
- 論文の詳細を見る
Methyl linoleate containing chlorophylls and/or pheophytins was exposed to light in the presence of oxygen. The photooxidative reaction of both chlorophylls a and b was first-order, and the reaction rate for chlorophyll a was higher than that for chlorophyll b. On the other hand, pheophytins a and b hardly decomposed even after irradiation for 24hr, and retained a green or a brownish-green color. In qualitative analysis of the photooxidation products of chlorophylls a and b, no pheophytins or pheophorbides were detected, while green and polar red pigments were observed on a thin layer chromatogram near the spot of chlorophyll and the origin, respectively. These photooxidation compounds also had prooxidant effects as well as did chlorophyll.
