Panu ginseng (6 Year old) was grown $17^{circ}C$/$15^{circ}C$ and $27^{circ}C$ day/$23^{circ}C$ night in the light room of phytotron for 84 days. The composition of neutral lipid(NL), glycolipid(GL), phospholipid(PL) and fatty acids were investigated in leaves. The contents of NL and GL were higher in $25^{circ}C$ while PL was lower. Similarity (simple correlation) of lipid composition between $16^{circ}C$ and $25^{circ}C$ was not significant for PL and GL but significant for NL(p = 0.001), indicating that PL and GL were important factors in the mostability. Similarity of fatty acid composition between growth temperatures was highly significant (p = 0.001) for all three lipids, while similarity between lipids was significant between NL and PL (p=0.01) and NL and GL (p=0.05), but nonsignificant between GL and PL at $16^{circ}C$. .In NL digalactosyldiacylglycerol (3->$7^{circ}$) increased but monogalactosyldiacylglycerol (10%) did not change at $25^{circ}C$. In PL phosphatidic acid (22 -> 4%) and phosphatidylinositol (18 -> 5%) decreased but phosphatidyl ethanolamine (12->l6%) increased at $25^{circ}C$. Percent unsaturated acid slightly decreased in NL and PL but greatly increased in GL at $25^{circ}C$. Percent unsaturated bond slightly decreased in NL but did not change in PL and GL.
