Objective : To isolate and identify the chemical constituents of the seeds of eucalyptus (Koelreuteria paniculata Laxm.) METHODS: The structures were determined by reflux extraction with petroleum ether and extraction with 95% EtOH. Column chromatography on silica gel, IR, MS, UV, 1HNMR and 13 CNMR. Results: 8 compounds were separated, 3 O tetradecanoyl 1 nitrile 2 methyl 1,2 propylene (1), 3 O eicosa 14,15 alkenoyl 1 nitrile 2 methyl 1,2 propylene (2), 3 O Eicosyl 14,15 Alkenoyl 4 O Octadecanoyl 1 Nitrile 2 Oxymethylene 1,2 Propene (3), 3 O (6’ Terengyl Glucose) β-Sitosterol (4) , 1 O β D Glucose 2 O Oleic Acid 3 O Hexadecanediglyceride (5), 1 O Hexadecanoate (6), 14, 15 Eicogase (7), III Glyceryl oleate (8). Conclusions: 1～3 are new compounds, and 4～8 lines were obtained from this plant for the first time and belonged to their spectral signals.
