| Abstract: | Objective To establish a headspace gas chromatography（HS-GC） method for the determination of chloroform residue in galanthamine hydrobromide.Methods The chromatographic column was the DB-624 quartz capillary column with temperature programming.The ECD detector was used with the temperature of 250 ℃,the inlet temperature was 200 ℃,and water was used as solvent.Results The linear range of chloroform concentrations was 0.12-6.0 μg/mL（r=0.999 9）.The average recovery rate was 99.1%（RSD=1.2%）.The quantification limit was 200 pg/mL.Conclusion The method is simple,accurate,highly sensitive and better reproducible,which can be used for the determination of chloroform residual in galanthamine hydrobromide. |
