目的: 建立顶空气相色谱测定甘草苷中大孔吸附树脂有机残留物的含量。方法: 采用HP-INNOWAX石英毛细管柱(0.32 mm×30 m
0.25 μm);以N
N-二甲基甲酰胺为溶剂
对正己烷、丙酮、苯、甲苯、二甲苯、苯乙烯等残留物进行检测。结果: 被测物质均能得到很好的分离
RSD均<3.0%
峰面积与浓度线性关系良好
回收率为93.2%~100.7%。结论: 该方法稳定、准确
适用于应用D-101型大孔吸附树脂纯化后原料药中有机溶剂残留物的检测。
Abstract
Objective: To build up a headspacemethod for detecting organic residues of D-101 macroreticular resin in liquiritin. Method: Using HP-INNOWAX capillary column (0.32 mm×30 m
0.25 μm).The purpose was to detect hexane
acetone
benzene
toluene
xylene
styrene and other residues
using N
N-dimethyl formamide as solvent. Result: Analytes can be well separated
the RSD were less than 3.0%
peak area and concentration had a good linear relationship
the recoverywas 93.2%-100.7%. Conclusion: This method is stable
accurate and suitable for use D-101 macroporous resin after the detection of residues of organic solvents.
