摘　　要：以翠云草叶片为试材,通过物理干燥和化学保色相结合的方法研究其保色工艺。物理干燥法采用自然干燥法、压花板干燥法、烘箱干燥法、熨斗干燥法和微波干燥法等5种不同方法;化学保色法采用浓度为1%、5%、10%、15%、20%蔗糖、葡萄糖、麦芽糖、硫酸铜溶液和浓度为2%、4%、6%、8%、10%氯化钙溶液,浸泡翠云草叶片(4 h、8 h、12 h、16 h、20 h),结合连续强光照射,研究不同种类保色剂对翠云草叶片的保色效果。结果表明,翠云草叶片最适合的干燥方法为熨斗干燥法;15%葡萄糖溶液浸泡翠云草叶片12 h保色效果最佳,其次为10%硫酸铜溶液处理12 h。The processes of color-keeping on pressed leaves was studied by means of physical drying and chemical color-keeping methods by using the leaves of Selaginella uncinata as materials.Physical drying methods adopted natural drying method,embossing board drying method,oven drying method,iron drying method and microwave oven drying method.Chemical color-keeping method adopted the concentration of 1%,5%,10%,15%,20%sucrose,glucose,maltose,copper sulfate solution and the concentration of 2%,4%,6%,8%,10%calcium chloride solution,soaked for 4 hours,8 hours,12 hours,16 hours,20 hours,combined with continuous strong light exposure to study the effect of different kinds of color preservatives on the color-keeping of pressed leaves.The results showed that the most suitable drying method was iron drying method.The best color-keeping effect was obtained when the leaves were soaked in 15%glucose solution for 12 hours,followed by 10%copper sulfate solution for 12 hours.
