摘要: 采用回流提取法提取红背桂(Excoecaria cochinchinensis Lour.)总黄酮,通过单因素试验,考察提取方法、提取溶剂体积分数、提取体积、提取时间对其药材总黄酮提取率的影响,采用正交试验优化提取工艺条件,筛选出红背桂总黄酮的最佳提取工艺。结果表明,红背桂总黄酮的最佳提取工艺为70%乙醇、料液比1∶40(g∶mL)、回流提取时间1.0 h。该方法能有效测定红背桂药材总黄酮含量,重复性较好、方法稳定、可行。

Abstract: The total flavonoids of Excoecaria cochinchinensis Lour. were extracted by reflux extraction method. The effects of extraction method, extraction solvent volume fraction, extraction volume and extraction time on the total flavonoid extraction rate of the medicinal materials were investigated by single factor experiment. The orthogonal test was used to optimize the extraction conditions. The best extraction process for a total flavonoid of Excoecaria cochinchinensis Lour. was screened out. The result showed that the optimal extraction process of a total flavonoid of Excoecaria cochinchinensis Lour. was 70% methanol, the ratio of material to liquid was 1∶40(g∶mL), and the reflux extraction time was 1.0 h. This method can effectively determine the content of total flavonoids in Excoecaria cochinchinensis Lour. The repeatability was good, the method was stable and feasible.

Key words: Excoecaria cochinchinensis Lour., total flavonoids, extraction process
