| 摘 要： | 目的:探讨在半枝莲提取工艺过程将黄金分割法作为筛选方法的可行性。方法:以野黄芩苷和总黄酮含量为考察指标,用黄金分割法和等距法筛选提取半枝莲的乙醇浓度的水平范围,以正交试验验证。结果:半枝莲的最佳提取工艺为15倍70%乙醇回流提取,提取3次,每次1 h。结论:将黄金分割法用于半枝莲提取工艺研究基本可行,可作为中药提取工艺的预筛选方法。

| Abstract: | Objective:To probe into the feasibility of golden section method in the optimization of the extraction process of Scutellaria barbata.Method:With the determination of the content of scutellarin and total flavonoids,selecting the range of alcohol concentration in the extraction of S.barbata was determined by the golden section method and method of equal interval,and validated it by orthogonal design.Result:The best extraction technique is that extract 3 times with 15 times of the alcohol which concentration is 70%,and each time for 1 h.Conclusion:Applying golden section method in the extraction of S.barbata is practical,which as a method of preliminary trial,indicates that golden section method can also be applied into the field of optimization of extraction process of traditional Chinese medicine. |
