摘要
目的:寻找一种有效纯化连钱草总黄酮的方法并对工艺条件进行初步摸索。方法:以连钱草总黄酮洗脱率和纯度为考察指标,确定大孔树脂分离纯化连钱草总黄酮的吸附和洗脱参数。结果:药液浓度(总黄酮浓度0.383mg/mL),上样量20mL,以1.0 mL/min的速度进行吸附,5 BV纯化水、10 BV 30%乙醇依次以1.0 mL/min的速度进行洗脱效果最佳,醇洗脱液浓缩后总干燥物中连钱草总黄酮的含量达68.94%。结论:该方法对连钱草总黄酮有较好的纯化作用,且工艺简单,成本低,具有良好的应用前景。
Objective:To study the purification process of total flavones from Glechoma longituba with macroporous adsorption resin. Methods:The eluting power and purified ratio of total flavones were selected as indices,the adsorbility and eluting parameters of the process were studied.Results:The best result that the purity of total flavones from Glechoma longituba could reach 68.94%was based on the followings:total flavones content in the liquid-0.383 mg/mL,feeding volume-20mL,feeding rate-1.0 mL/min,eluting agent -5BV purify water and 10BV 30%ethanol,eluting rate-1.0 mL/min.Conclution:The process is simple and convenient which can be used in the purification of total flavones from Glechoma longituba,it may has a good application foreground.
