目的研究大孔树脂纯化天山雪莲有效成分的工艺条件。方法以紫丁香苷、绿原酸和芦丁的吸附量和解吸率为评价指标,筛选树脂,并优化了吸附和洗脱条件。结果HPD400型树脂对天山雪莲各有效成分具有较好的吸附分离性能,适于纯化天山雪莲有效部位。最佳工艺条件为:雪莲样品溶液4BV,上样液的pH值为2～3,吸附流速1BV/h,吸附时间为12h,先用4BV水洗涤,再用30%、50%乙醇各6、4BV进行梯度洗脱,流速1BV/h,合并30%、50%乙醇洗脱液,即为目标产品。各有效成分的质量分数均提高了5倍左右。结论采用HPD400树脂分离纯化天山雪莲中有效成分是可行的。

Objective To study the technological parameters of the purification process for active cons-tituents from Saussurea involucrata.Methods Using absorption and desorption rates of syringin,chologenic acid,and rutin as the primary screening indexes,four resins were selected,and the conditions of absorption and desorption were optimized for active constituents.Results Resin HPD400 gave good separation performance and was selected to purify the active constituents in S.involucrata.The optimum parameters were established as followings:4 BV(bed volume)sample extract whose pH value was adjusted to pH 2-3 by HCl was passed through the column with a flow rate of 1 BV/h,12 h later,the column was washed with 4 BV water,6 BV 30% ethanol and 4 BV 50% ethanol,respectively.The combined 30% and 50% ethanolic elutes were taken as object products.Conclusion The contents of active constituents were increased to about five times.Macroporous absorption resin HPD400 could be well used in separating and purifying the active constittuents from S.involucrata.
