Abstract: Methanol and acetone were used to extract heartwood of Olag hay larch (Larix olgensis Henry) by internal reflux method, then the extracts were distilled, and the distillates were analyzed by gas chromatography-mass spectrometry(GC-MS). Nine compounds, or 4 kinds of compounds in methanol extract were identified, including phenols(3 types, 20.344%), esters(4 types, 48.169%), acid(1 type, 11.740%), phenanthrene(1 type, 8.345%). Nineteen compounds, or 7 kinds of compounds in acetone extract were identified, including phenols(8 types, 19.965%), phenanthrenes(4 types, 8.987%), acids(2 types, 15.738%), esters(2 types, 16.160%), indene(1 type, 3.172%), naphthalene(1 type, 0.550%), and alkene(1 type, 0.504%).

Key words: Larix olgensis Henry, heartwood, extraction, distillation
