| 摘 要： | 目的：优选樱草杜鹃中总黄酮的最佳提取工艺。方法：以芦丁为评价指标,考察黄酮质量分数,通过正交试验对超声法提取黄酮的工艺进行优化。结果：超声提取法的最佳工艺条件为以樱草杜鹃叶为原料,75%乙醇为提取液,m（樱草杜鹃）∶v（提取液）=1∶10,超声时间为60min,提取3次;在该条件下,总黄酮的提取率为11.01%,RSD为0.43%（n=3）。结论：优选了樱草杜鹃总黄酮的最佳提取工艺,提高药材的利用率,为更好地利用该药材提供了理论依据。

| Abstract: | Objective：To optimize the best extraction technology of flavonoids in leaves of Rhodendron primulaeflorum Bur.et Franch.Methods：For the evaluation of rutin to study the mass fraction of flavonoids,ultrasonic extraction process was optimized flavonoids by orthogonal test.Results：The optimum ultrasonic extraction conditions as follows：the Rhodendron primulaeflorum Bur.et Franch.leaves was as raw material,75% ethanol for the extract,m（Rhodendron primulaeflorum Bur.et Franch.）：v（extract） was 1：10,ultrasonic was 60 min,extracted three times;in this condition,the extraction rate of flavonoids was 11.01% with a RSD of 0.43%（n=3）.Conclusion：Optimize the best extraction technology of flavonoids in Rhodendron primulaeflorum Bur.et Franch.leaves and improve the utilization of medicinal herbs in order to better use of the medicine provides a theoretical basis. |
