Objective: To study the quantitative method of oleic acid in Brucea javanica oil. Methods : The content of oleic acid was determined by dual wavelength thin-layer scanning method. The λs was 40 nm and the λR was 650 nm. Results: The average recovery rate was 98 7%, with an RSD of 22%. Conclusion : This method provides the basis for evaluating and controlling the quality of Brucea javanica
