The seeds of Korean pine, Pinus koraiensis, had been used as one of edible fruits for long time, but its chemical analysis of the nutrient components was extremely limited. The purpose of this study is to analyze the content of chemical components of Korean pine seeds. The results obtained are as follows : 1. In general analysis of Korean pine seeds, moisture is 4.4%, crude protein 18.3%, crude fat 67.3%, crude fiber 4.7%, ash 2.2%, and nitrogen-free extract 3.4%, respectively, 2. The Korean pine seed contained 18 different kinds of amino acid : lysine, histidine, arginine, aspartic acid, threonine, serine, glutamic acid, proline, glycine, alanine, valine, methionine, isoleucine, leucine, tyrosine, phenylalanine, cysteic acid, and tryptophan. The glutamic acid is highest content among 18 kinds of amino acid. 3. The Korean pine seed contains all the essential amino acids such as arginine, histidine, lysine, threonine, valine, methionine, isoleucine, leucine, phenylalanine, and tryptophan. 4. The Korean pine seed contains 13 different kinds of fatty acid such as myristic acid, palmitic acid, palmitoleic acid, stearic acid, oleic acid, linoleic acid, linolenic acid, arachidic acid, 9-icosenoic acid, 9, 11-icosenoic acid, 8, 11, 14-icosatrienoic acid, and tn-o unknown substances. Also it contains all the essential fatty acids as linoleic acid and linolenic acid. The linoleic acid is highest content among 13 kinds of fatty acid. 5. The Korean pine seed contained 5 different kind., of vitamin such as vitamin A, vitamin $B_1$, vitamin $B_2$, vitamin E and niacin. The content of vitamin E is the largest among 5 kinds of vitamin.
