叶绿素色素包括叶绿素a、叶绿素b、胡萝卜素和叶黄素等主要组份。用硅藻土G、硅胶、纤维素或其混合物等不同物质作载体,用薄层色谱法分离叶绿素已有过报道。色谱法分离叶绿素现在已被一些高校列为无机化学专业实验。我们曾用纤维素作载体让学生做实验,由于制板后蓬松、分离效果也不好,作者试图作些改进。就制板和使用方便,硅胶G是理想的载体,尽管M.F.Bacon指出在硅胶G上分离叶绿素时,叶绿素a保持在基线上,但我们 Chlorophyll pigments include chlorophyll a, chlorophyll b, carotene and lutein and other major components. The use of different materials such as diatomaceous earth G, silica gel, cellulose or mixtures thereof as carriers for the separation of chlorophyll by thin-layer chromatography has been reported. Chromatographic separation of chlorophyll has now been some colleges and universities as inorganic chemistry experiment. We used cellulose as a carrier for students to experiment. Because the system was fluffy and separation effect was not good, the author tried to make some improvements. Silica gel G is the ideal vehicle for ease of handling and ease of use, although M.F. Bacon states that while chlorophyll is isolated on silica G, chlorophyll a remains at baseline, but we
