摘要: 研究大孔树脂对蒲公英中绿原酸和咖啡酸的富集工艺。利用高效液相色谱法建立绿原酸和咖啡酸的含量测定方法,采用单因素和正交试验优化富集工艺。最佳工艺条件是以XDA-1B树脂为载体,树脂:药材(g:g)=1:5,上样液(pH为3)浓度为40 g(以药材计)/L,吸附流速4 BV/h,水洗脱8BV(流速1 BV/h),20%乙醇洗脱9BV(流速0.5 BV/h),富集物中绿原酸和咖啡酸的含量和转移率分别为50.32±0.74%、91.26±1.06%、37.94±0.67 %和90.14±0.93%(n=5),总含量为88.18±1.22% (n=5)。不同质量树脂(20~640 g)的含量和转移率差别无统计学意义。树脂可重复使用4次。工艺简便、稳定、线性宽、耐用性强,能够获得高含量和高转移率的有效部位富集物。

Abstract: To study enrichment technology of chlorogenic acid and caffeic acid from Taraxacum mongolicum by macroporous resin.Determination method of chlorogenic acid and caffeic acid was established by HPLC.Preparation technology was optimized by mono factor test and orthogonal test.The optimal conditions were using XDA-1B macroporous resin,resin:Taraxacum (g:g) =1:5,the concentration of sample solution (pH3) was 40 g (Taraxacum)/L,the adsorption flow rate was 4 BV/h,The sample was eluted by water with 8 BV(flow rate was 1 BV/h) and 20% ethanol of 9 BV(flow rate was 0.5 BV/h),respectively.The content and transfer rate of chlorogenic acid and caffeic acid in enrichment were 50.32±0.74%,91.26±1.06%,37.94±0.67% and 90.14±0.93% (n=5),total content was 88.18±1.22% (n=5).The content and transfer rate was no difference by the resin with different mass (20-640 g).The resin could be repeatedly used for 4 times.The process was simple,stable,linear width,strong durability,to obtain enrichment of effective parts with high content and high transfer rate.
