Abstract本发明公开了一种叶绿素铜酸及铜钠盐的制备方法,包括以下具体步骤:取新鲜植物茎叶,加入90%~95%乙醇,打浆提取,压榨取汁;汁液经过180~300目纱布粗滤后,4000~6000rpm高速离心;加5%NaOH溶液调节pH到11~12皂化,减压浓缩回收乙醇;调pH到2~3,加10%CuSO4溶液铜代;抽滤后得到的沉淀先后经过三次温水洗涤和三次低度乙醇溶液洗涤;得到的沉淀可直接烘干,得到叶绿素酮酸固体粉末;洗涤后的沉淀用丙酮溶解;加5%NaOH乙醇溶液调pH10~12,洗出沉淀,抽滤后烘干,得到叶绿素铜钠盐固体粉末。该制备方法的回收率为0.7~1.0%,得到的叶绿素铜钠盐符合GB36406-2011标准的各项要求。该制备方法将浓缩和皂化两大耗时步骤和在一起,大大减少耗时,省去了有机溶剂萃取步骤,简化了工艺,降低了成本。
