摘  要:
以新疆和田玉枣为原料,采用正交试验设计通过香草醛-高氯酸显色法对不同超声处理条件下的和田玉枣粗提物中总皂甙含量进行测定,优化和田玉枣总皂甙超声提取工艺。结果表明:超声提取和田玉枣总皂甙的最佳工艺为超声功率150W、乙醇体积分数70%、料液比1:12(g/mL)、提取时间30min,测得和田玉枣粗提物中总皂甙含量为9.358mg/g。该提取方法简便、快捷,可用于和田玉枣总皂甙提取和测定。

摘  要:
Total saponins from Hetian-jade jujube were extracted by an orthogonal array design and determined by color development reaction with vanillin and perchloric acid.The results showed that the optimal extraction conditions were as follows:70%of ethanol concentration,1:12 of ratio of raw material to liquid,and 30 min of extraction time.The content of total saponins in the crude extract obtained under the above conditions was 9.358 mg/g.A convenient and quick process has been presented for the extraction of total saponins from Hetian-jade jujube.
