In order to find more biodiesel plants and develop biodiesel industry, the species composition, distribution and present situation of utilization of wild oil plant resources in Sichuan Province were investigated and analyzed. 367 species of oil plants were collected, and according to the National biodiesel quality standards, some indicators are measured. The oil content of seeds or kernels of 156 species are more than 10 percent. There are 55 species with oil content over 30 percent, among which 11 species are rich in Saturated fatty acids, 11 species rich in Oleic acid, 15 species rich in Linoleic acid and 3 species rich in Linolenic acid respectively. 13 species of non-food biodiesel plants are screened out based on the quality indexes of biodiesel. 11 species are sustainable for development and utilization being the biodiesel plants. This result can be an important reference for Sichuan biodiesel industry development.
