摘 要: 在单因素试验的基础上,利用L9(34)正交试验法研究了竹叶中叶绿素的提取工艺。结果表明,以乙醇为溶剂,竹叶叶绿素的最佳提取条件为:乙醇体积分数80%、液固比25∶1.5(mL∶g)、提取温度60℃、提取时间3.5 h,叶绿素的得率0.49%。制备的糊状叶绿素,检验结果符合化工产品企业标准。 The extraction technology of chlorophyll from bamboo leaf was studied through L9 (34) orthogonal experiment based on single factor tests. The results indicated that the optimum chlorophyll extraction conditions were as follows : 80 % ethanol ( volume fraction) , ratio of liquid to solid as 25 : 1.5 ( mL: g) extraction for 3.5 h under 60 ℃. According to this extraction technology, the yield of chlorophyll was up to 0.49 %. The prepared paste chlorophyll was examined to reach the factory standard.
