| 摘 要： | 考察了引种于俄罗斯的大果沙棘不同部位总黄酮含量的差异。用超声提取作为沙棘总黄酮的制备方法;以芦丁为对照品,采用分光光度法作为沙棘总黄酮的测定方法。实验结果表明,沙棘叶、果肉和果皮中总黄酮含量分别为1.71%、0.76%和0.55%,叶中总黄酮含量分别是果肉和果皮的2.3倍和3.1倍,因此引种于俄罗斯的大果沙棘叶具有较大的开发价值和应用前景。

| Abstract: | The content distribution of total flavonoids in different parts of Hippophae rhamnoides L. from Russia was investigated. The sample pretreatment process involved ultrasonic extraction. The total flavonoids were determined by spectrophotometry, rutin as control sample. The experiment results showed that the contents of total flavonoids in leaf, pulp and pericarp were respectively 1.71% , 0.76% and 0. 55% , that the means content of total flavonoids in leaf is 2.3 and 3.1 times higher than that in pulp and pericarp. Thereby the leaf of Hippophae rhamnoides L. from Russia has value to be developed and used. |
