A solution headspace gas chromatography for the determination of residual organic solvent in Artemether was established. A DB-1 wide bore capillary column was used with Referencel standard.The linear range for methanol, ethanol and dichloromethane were 30.2-635.2 μg·mL^-1(r=0.9991), 6.4-64.5 μg·mL^-1 (r=0.9991) and 5.5-68.7 μg·mL^-1 (r=0.9990) respectively. The average recoveries of methanol, ethanol and diehloromethane were 99.9%, 103.8%and 99.3%respectively. The lowest test limits of methanol , ethanol and dichloromethane were 0.02 μg·g^-1, 0.04 μg·g^-1 and 0.01 μg·g^-1 ,respectively. The method was simple, accurate, sensitive and repeatable.
