Abstract:
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.
