摘　　要：以荷叶为原料,丙酮为溶剂提取获得叶绿素,经过皂化、酸化、铜代等过程,制备得到叶绿素铜钠盐,并测定了其对光、热及几种常见金属离子的稳定性.结果表明,叶绿素铜钠的热稳定性较差,对自然光有一定耐受能力,且具有较好的耐受还原剂的能力.Chlorophyll was extracted from leaves of Lotus by use of acetone as solvent.Sodium copper chlorophyllin was prepared from the chlorophyll extract through the processes of saponification,acidification,and copper substitution.Moreover,its photo-stability,thermo-stability and the stability to some of the commonly-seen metal ions were determined.The findings revealed that the sodium copper chlorophyllin was of a poor thermal stability,yet its photo-stability was satisfactory and exhibited a rather good tolerance of reducing agents.
