摘要
目的:探讨超声强化提取玉屏风总糖的最佳工艺条件,比较玉屏风总糖的复方和单方提取的优劣。方法:利用正交设计试验确定玉屏风总糖最佳提取工艺,与常规提取方法进行比较,并比较玉屏风总糖的复方整体和单方提取率。结果:结果表明最佳工艺条件为固液比1∶20,超声温度55℃,超声时间20 min,此优化条件下,复方玉屏风总糖的提取率为14.25%,浸渍180 min的提取率为5.44%,常规搅拌180 min的提取率为7.35%。结论:与传统提取方法 (浸渍法和搅拌法)比较,超声提取具有省时、节能、高效等优点,为现代药企进行大规模、高效率的生产提供了充分条件。
Objective：To investigate optimum extraction technology conditions of polysaccharides from Yupingfeng by ultrasonic-assisted extraction,and to compare extraction rate of polysaccharides between compound extraction and unilateral extraction.Method：Optimum extraction conditions were obtained by orthogonal design test,compared with traditional extraction technology,and compared extraction rate of polysaccharides from Yupingfeng by compound extraction and unilateral extraction.Result： Result showed that optimum technology conditions were：ultrasound temperature 55 ℃,ratio of solid-liquid 1∶20,ultrasonic time 20 min,under these optimum conditions,extraction rate of polysaccharides from Yupingfeng was 14.25%,extraction rate of impregnation method was 5.44% in 180 min,extraction rate of conventional mixing method was 7.35%.Conclusion： Compared with traditional extraction methods（impregnation method and mixing method）,ultrasonic extraction had some advantages,such as time-saving,energy saving,high efficiency and so on.It offered sufficient conditions for large-scale and efficient production of modern medicine enterprises.
