摘要
用甲醇和丙酮分别对长白落叶松心材进行热回流提取,并对2种提取物蒸馏,用气相色谱-质谱(GC-MS)对蒸馏产物进行分析。甲醇提取物的蒸馏产物中有9种主要化学成分被鉴定,占总量的88.598%,其中有酯类(4种,48.169%)、酚类(3种,20.344%)、酸类(1种,11.740%)、菲类(1种,8.345%)共4类化合物;丙酮提取物的蒸馏产物中有19种主要化学成分被鉴定,占总量的65.076%,其中有酚类(8种,19.965%)、菲类(4种,8.987%)、酸类(2种,15.738%)、酯类(2种,16.160%)、茚类(1种,3.172%)、萘类(1种,0.550%)、烯类(1种,0.504%)共7类化合物。
Methanol and acetone were used to extract heartwood of Olag hay larch （Lar/x 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 % ）.
