Abstract: We analyzed the oils from the seeds or fruits of 100 species of the Chincse plants which belong to 71 genera of 41 families. Their contents, refractive index, specific gravity, saponification value, acid value, and iodine value were examined. The quantilative determination of fatty acid was also made by means of GLC. According to the results of the experiment, the percentages of various saturated fatty acids, unsaturated fatty acids, and uses of oils in Compositac, Styracaceae, Oleaceae, Theaceae, Lauraccae and Guttiferae were mainly discussed in this paper.

Key words: Chinese plants, oils, component, acids
