摘要

目的: 建立当药提取物中大孔树脂残留物的检测方法。方法: 采用顶空气相色谱法测定当药提取物中大孔树脂残留物(正己烷、苯、甲苯、二甲苯、苯乙烯、二乙基苯及二乙烯苯)含量。结果: 7种成分均获得较好的分离

且呈良好线性关系(r为0.994 0~0.999 7)

平均回收率93.4%~98.4%

精密度RSD均<10%

3批样品中均未检测出7种树脂残留物。结论: 该方法简便快速、准确、重复性好

可用于大孔树脂有机溶剂残留量的测定。

Abstract

Objective: To Establish a method for detecting residues of macroporous resin in extract of Swertia pseudochinensis. Method: Headspace-GC was used to determine the content of macroporous resin residues of n-hexane

benzene

methylbenzene

dimethylbenzene

phenylethylene

diethylenzene

divinylbenzene in extract of S. pseudochinensis. Result: All of seven residues were separated and good linear responses were obtained in the mass concentration with r between 0.994 0 to 0.999 7.The average recoveries of these 7 residues were in the range of 93.4%-98.4% with RSD<10%

these 7 residues were not detected in three batches of samples. Conclusion: This analytical method was convenient and accurate with good repeatability

it could be used to determine organic solvents residues in macroporous resin.
