摘要： 对不同表面活性剂协同芦丁提取的效果进行了比较,筛选出对芦丁提取具有较好协同作用的表面活性剂———吐温20(Tween20)。通过试验,得到了Tween20协同提取芦丁的最佳工艺条件:提取两次,每次槐米与水、硼砂及Tween20的质量比为100:700:0.75:0.5,在60℃下提取30min。合并提取液,用盐酸调pH值至2～3,静置40min,分离出沉淀物,干燥,即得芦丁,产率为17.5%,纯度为92.5%。与传统碱水提取法相比,Tween20协同芦丁提取法能缩短提取时间和沉淀时间并提高芦丁产率。

Abstract: Different surfactants were used as assistants to extract rutin from Flos sophorae,from which Tween 20 was confirmed as the best surfactant. The optimal technology is obtained as follows: extracting twice at 60℃ for 30 min,each time with a mass ratio of material to solvent, Tween 20 and borax by 100:700:0.75:0.5,adjusting the extracted liquor′s pH value to 2-3 with 15% hydrochloric acid,laying aside for 40 min to deposit completely followed by separating out the precipitate.Rutin product can be obtained at yield 17.5% and purity 92.5% after drying of the precipitate. Compared with traditional alkaline liquor extraction, the extraction assisted with Tween 20 has the advantages of decreased extracting time and depositing time,and increased yield.

Key words: surfactant, Tween 20, rutin, Flos sophorae
