摘要
为研究青钱柳叶总三萜化合物超声辅助提取的最佳工艺条件,在考察了乙醇浓度、料液比、提取时间、提取温度、提取级数、超声功率、提取溶剂等单因素的基础上,采用L9(34)正交设计确定在多因素条件下青钱柳总三萜提取的最佳工艺。结果表明,最佳提取工艺条件为:70 %的乙醇、料液比1〖DK〗∶40,在400 W条件下超声45 min。采用该提取方法所得青钱柳叶总三萜平均得率为222 %。该优化工艺稳定,适合于青钱柳叶三萜类化合物的提取。
Abstract
To study the optimum technological conditions of ultrasonicassisted extractiny triterpenoid compounds from Cyclocarya paliurus leaves, on the basis of single factor experiments(ethanol concentration, ratio of solvent to material, extraction time, extraction temperature, extraction times, ultrasonic power, extraction solvent), the experiment was designed with L9(34). The results indicated that 70 % ethanol solution, 1〖DK〗∶40 between material and extraction solution, 400 W ultrasonic power and 45 minutes for extraction were optimum conditions. With the optimized technology, the average yield is 222 %. The technology is relatively stable,so it is suitable for extraction triterpenoid compounds from Cyclocarya paliurus leaves.
