A head-space capillary GC method was established for the determination of resin residues in mulberry twig total alkaloids extract. The DB-624 column was used for the determination of n-hexane, benzene, methylcyclohexane, toluene and divinylbenzene, and the DB-WAX column was used for the determination of xylene and styrne, with nitrogen as the carrier gas, FID detector and temperature programmed control. Standard addition method was used. Seven residual solvents were separated completely. The calibration curve for benzene was linear in the range of 0.2 -10 μg while those for the others were linear in the range of 2 - 100 μg. The recoveries were 96.6% - 101.7% with RSDs less than 10%.
