| 摘要: |
| 以总黄酮为指标,优化聚花过路黄醇提取工艺条件,采用正交设计法进行试验;结果表明:过路黄的乙醇回流提取最佳工艺条件为乙醇体积浓度的55%左右,提取次数为3次,溶剂用量为投料量的8倍,提取时间为每次2 h;按优化条件测定的重庆产聚花过路黄总黄酮的质量分数为10.980 6 mg/g。 |

| Abstract: |
| In order to study the extraction process for the total flavones of Lysimachi congestifloa Hemsl,the optimum extraction process was selected with the oethogonal design.The contant of total flavones was determined by UVspectrophotometry.The siginficant effe |
