説明

Effects of monochromatic lights on the photolysis of chlorophylls and their derivatives were studied.<BR>Chlorophyll a and b were significantly degraded by irradiation with the wave length under 300 nm of ultraviolet light, and at the same time were considerably degraded by visible light around their absorption maxima.<BR>Pheophytin a and b were also significantly degraded by irradiation with the wave length under 300nm of ultraviolet light, while in the visible region, their discolorations were not observed. Chlorophylline a and b were more susceptible to irradiation of light than chlorophylls, especially in the visible region.<BR>The relative stability between chlorophyll a and b or pheophytin a and b to light varied with the solvent systems used.
