摘要
目的:建立银杏叶片中9种大孔树脂有机溶剂残留物的检测方法。方法:采用顶空气相色谱法测定大孔树脂残留物正己烷、苯、甲苯、邻二甲苯、间二甲苯、对二甲苯、苯乙烯、二乙基苯和二乙烯苯的含量。结果:9种大孔树脂残留物得到较好的分离,呈良好线性关系(r为0.999 2-0.999 8),精密度良好,平均回收率为80%-110%。结论:该方法准确快捷,灵敏度高,适用于银杏叶片中树脂残留物的检查。
This study was aimed to establish the determination method of nineorganic solvent residues of macrop-orous resin. Headspace capillary gas chromatography （GC） was used in the content determination of hexane, benzene, methyl-benzene, o-xylene, m-xylene, p-xylene, styrene, diethyl-benzene and divinyl-benzene of macroporousresin residues in Ginkgo leaf tablets. The results showed that ninemacroporous resin residues in Ginkgo leaf tablets were completely separated. The calibration curves were in good linearity （r=0.9992-0.9998）. The average recoveries were 80%-110%. It was concluded that themethod was accurate, quick, and sensitive, which can be used to determine the macroporous resin residues in Ginkgo leaf tablets.
