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

摘要： 本文根据我国一百种油脂植物（隶41科，71属的种于成果实，进行了含油量、折光率、比、皂化值、碘值等理化常数的测定，运用气相色谱仪对它们的常见脂肪酸进行了定量．根据分析结果本文着重讨论了在菊科、安息香科、木樨科、茶科、樟科和藤黄科油脂植物中各种常见的饱和脂肪酸和不饱和脂肪酸的含量及其利用价值．
