感冒灵清膏干燥工艺的研究

Study on Drying Process of the Gan-Mao-Ling Liquid Extract

摘要: 目的：优选出感冒灵清膏最佳且适合大生产的干燥工艺参数。方法：采用高效液相色谱法检测样品中蒙花苷的含量，以蒙花苷的保存率为指标，比较了减压真空干燥、真空连续带式干燥、微波干燥三种干燥方式。结果：采用真空连续带式干燥温度控制在70度以下，蒙花苷保存率高达98.85%，并且干燥时间短。结论：真空连续带式干燥方便快捷、对热敏性物质稳定、产量高、适合大生产。

Abstract: Objective: To optimize the best and suitable drying process of the Gan-Mao-Ling liquid extract for large-scale production. Methods: Using high performance liquid chromatography to determine the contents of buddleoside and comparing decompression vacuum drying, continuous vacuum belt drying and microwave drying by the standard of buddleoside retention. Results: The continuous vacuum belt drying temperature was controlled at 70 degrees or below, buddleoside retention is up to 98.85%. Conclusion: Continuous vacuum belt drying is fast and convenient, for heat-sensitive material stability, high yield, suitable for large-scale production.
