芳香新塔花挥发油化学成分的GC/MS分析

Analysis on Chemical Constituents of Essential Oil from Ziziphora clinopodioides Lam. by GC/MS

摘要: 运用水蒸气蒸馏法提取挥发油，采用气相色谱-质谱联用技术（GC/MS）对挥发油成分进行分离鉴定，并采用面积归一化法确定各成分的相对百分含量。从3个样本中分别鉴定出10种、16种和19种挥发油成分，占各自挥发油总量的99.62%、99.71%和99.28%。3个采集地的芳香新塔花的主要成分相同，均为长叶薄荷酮和薄荷酮，两者总量分别达到了89.02%（乌鲁木齐市雅山样品）、83.51%（乌鲁木齐市南郊样品）和87.11%（新疆布尔津县禾木乡样品），其他主要成分为异薄荷酮、胡椒烯酮、异长叶薄荷酮、柠檬烯等。

Abstract: The essential oil of Ziziphora clinopodioides Lam. from three specimens was extracted using steam distillation.The chemical components of the essential oil were analyzed by GC/MS. 10, 16 and 19 components are identified from three specimens,which accounted for 99.63%, 99.70% and 99.28% of volatile fraction， respectively. The major components are pulegone and menthone, which accounted for 89.02%(Yamalike Hill at Urumqi), 83.51%(southern suburbs of Urumqi)and 87.11%(Horm rural Buerjin county of Xinjiang). Others are isomenthone, piperitenone,isopulegone and limonene et al.
