This study examined the changes of chemical components in Dongchimi when ginseng and pineneedle were added 0.1% and 0.3%, respectively. Those were fermented at room temperature for the first day and at 4$^{\circ}C$ from the second to 29th day. The contents of reducing sugar was significantly increased during fermentation, and showed the highest content in Dongchimi added pineneedle. The contents of proteins were also increased in the Dongchimi with pineneedle during 8 days of fermentation, while the others increased throughout 29 days of fermentation. The contents of non-volatile organic acids were 2.79~4.80 mg/100 ml at the end of fermentation, and the content of lactic acid was the highest among them. Free sugars of the Dongchimi were composited sucrose, glucose and fructose, and the contents of those were in the range of 227.4~247.0 mg/100ml in 8 days of fermentation, then increased to 705.2~943.7mg/100ml in 29 days. the Dongchimi contained 17 kinds of free amino acids except lysine, arginine were the majority of them, and sarcosine, $\beta$-aminoisobutyric acid and ${\gamma}$-aminoisobutyric acid were the major portion of amino acid dervatives.
