A GC-MS method for the determination of three kinds of root inhibitors in asphalt-based waterproof coiled material was established,and the internal standard method was used for quantifincation.The samples were extracted by ultrasonic extraction of methylene chloride.The pretreatment time was short and the operation was simple.In the concentration range of 10～150mg·L-1,the linearity ship was good,and the correlation coefficients were all greater than 0.99.The recoveries at the 0.3％spiked level were 98.6％～114.2％and the precision was 1.08％～1.65％.The method is fast and accurate,and can meet the need of the content determination of root inhibitor asphalt based waterproof coiled material.
