The aim of this work is to explore the extraction conditions of Pistacia chinensis bunge oil and to optimize the technological parameters for preparing biodiesel. Results: The proper conditions of extracting the oil are ratio of petroleum ether volume to seed mass 5 : 1, reaction time 2 h, and reaction temperature 70 ℃. The oil yield is 31.8 %.The optimum conditions of transesterification with Pistacia ehinensis bunge oil obtained by L9 (34) orthogonal experiments are as follows: mass ratio of oil to methanol 1:6, catalyst dose 1.2%, reaction time 2 h, and reaction temperature 60 ℃.The conversion rate is 96.0 %. The performance index values of the produced biodiesel are close to No. 0 diesel, so it is an ideal substitution to No. 0 diesel.
