仙人掌叶绿素的提取及叶绿素铜钠盐的制备工艺研究

Study on extraction processing of chlorophyll and preparation of sodium copper chlorophyllin from cactus

探讨了"米邦塔"仙人掌叶绿素的提取及制备叶绿素铜钠盐的工艺条件。结果表明,仙人掌叶绿素最佳提取工艺条件为:以80%丙酮及95%乙醇比例为3:1的混合溶液作浸提剂,料液比1:45,浸提温度40℃,浸提时间5h;提取的叶绿素,经过皂化、酸化、铜代、成盐等工序制成叶绿素铜钠盐,产品质量符合国家标准GB3262-82。

The extraction process of chlorophyll and the preparation of sodium copper chlorophyllin from cactus were studied.The results showed ：the solvent was 80% acetone and 95% ethanol ratio of 3：1 ,the ratio of solute to solvent was 1：45 ,the temperature was 40℃ and the extracting time was 5 hours.Then sodium copper chlorophyllin was made by chemical progressing. The sodium copper chlorophyllin＇ s quality measures up to the national standard GB3262-82.
