Beschreibung: Biodiesel is one of the most important bioenergy products. But the feedstock is the bottleneck of its production. In order to mine potential feedstock from the natural resources, a wild survey was conducted in 10 provinces or cities of North China, and 952 seed samples, which came from 587 species of 102 families, were collected for analysis of oil content, oil composition, and chemical properties. The result showed that there are 23 families with the average oil contents higher than 20%, and families of Lauraceae, Magnoliaceae, Celastraceae, Brassicaceae, Labiatae, Sapindaceae are dominant families rich in oil. The fatty acid composition of various vegetable oils is very different, showing the characteristics of different families, genera, and species. Erucic acid was mainly found in the Cruciferae；Pinolenic acid and taxoleic acid was mainly found in the Pinaceae; Oleic acid was mainly found in the Euphorbiaceae. The average iodine value in 81.4% of the families is less than 120 g/100g. Families with an acid value of less than 10 are mainly distributed in Rosaceae, Leguminosae, Cruciferae, Labiatae, Compositae, Liliaceae, Aceraceae, Rhamnaceae, Solanaceae, Cannabaceae, Malvacea, Oleaceae, Cornaceae, Sapindaceae, etc. The saponification value is concentrated between 140 and 220 mg/g in 344 species (62.66%). In 84 species (60.87%), the predicted cetane number is higher than 49, mainly distributed in the families of Rosaceae, Anacardiaceae, Betulaceae, Fagaceae, Oleaceae, Umbelliferae, Theaceae, Celastraceae, etc. These results will help in developing potential biodiesel feedstock, also provide a guide for development of specific oil industry
