This study was undertaken to analyze proximate comosition, mineral contents and fatty acid composition of pure jemsosojoo(PJ) and jemsosojoo added medicinal herb(JMH). Mositure, ash, crude protein and crude fat of pure jemsosojoo were higher than those of the JMH, but carbohydrate content was higher in the JMH. Among minerals, Ca, Mg, Fe, Zn content of the JMH were higher than those of the PJ, while P and Na were higher in the PJ and those difference were significant between the PJ and the JMH(p<0.05). U/S (unsaturaed fatty acid/saturated fatty acid) ratio was higher in the JMH than those of the PJ, the ratio o fglycolipid was 1.75 in the PJ and that of neutral lipid was 3.07 in the JMH. Octadecenoic acid, hexadecanoic acid, octadecenoic acid and hexadecenoic acid were major fatty acids in the total lipids, neutral lipids glycolipids and phospolipids of the PJ and the JMH. Especially, octadecadienoic acid and octadecatrienoic acid were higher in the JMH than those of the PJ.
