奇楠沉香挥发油化学成分分析

摘要

The volatile oil was extracted from tagara agarwood by water steam distillation.Chemical constituents of volatile oil was analyzed by gas chromatography-mass spectrometry,the relative content of these chemical constituents were calculated using square peaks to normalization.As a result,36 chemical constituents were isolated and identified in the volatile oil from tagara agarwood.It was found that the main constituents of this volatile oil are sesquiterpenes,which comprised more than 76.31 % of total volatile oil from agarwood.The major characteristic constituents from agarwood are Baimuxinal（36.31 %）,α-agarofuran（3.18 %） and Agarospirol（1.73 %）.%采用水蒸气蒸馏法提取奇楠沉香挥发油,通过气相色谱-质谱联用分析手段对奇楠沉香挥发油的主要成分进行分析,并采用峰面积归一化法确定各组分的相对含量。结果,本实验从奇楠沉香挥发油分离鉴定出36个组分,占挥发油总量的94.57%,其中倍半萜类化合物含量最高,占挥发油总量的76.31%。奇楠沉香挥发油中含有的沉香特征性倍半萜类成分白木香醛、α-沉香呋喃和沉香螺旋醇的含量分别为36.31%、3.18%和1.73%。
