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 the optimum conditions of ultrasonic extraction of total sugar in Jade Screen, and to compare the advantages and disadvantages of the compound and unilateral extraction of total sugar in Jade Screen. Methods: The optimal extraction process of total sugar of Yuping wind was determined by orthogonal design test, compared with the conventional extraction method, and the overall and unilateral extraction rate of the total sugar of Yupingfeng was compared. Results: The optimum conditions were as follows: solid-liquid ratio 1:20, ultrasonic temperature 55 ℃ and ultrasonic time 20 min. Under the optimum conditions, the extraction rate of total sugar of JFB was 14.25% 5.44%, the extraction rate of conventional stirring 180 min was 7.35%. Conclusion: Compared with the traditional extraction methods (impregnation method and stirring method), ultrasonic extraction has the advantages of saving time, saving energy and high efficiency, which provides sufficient conditions for the large-scale and high-efficiency production of modern pharmaceutical enterprises.
