【摘要】：为研究艾叶化学成分与其产地之间关系,分别以产自河南南阳和新疆的艾叶为实验材料,对比研究其酚类化合物和挥发油的组成。以体积分数60%乙醇溶液为溶剂超声提取酚类化合物,高效液相色谱法结合标样检测其组成;同时蒸馏萃取结合气相色谱-质谱联用检测挥发油的化学成分。结果表明,河南南阳和新疆艾叶挥发油得率分别为2.644%、0.805%;河南南阳、新疆艾叶分别检测出标准品中的19种和14种酚类化合物,总含量达13.43 mg/g和9.75 mg/g;挥发油中分别鉴定出29种和12种化合物,占挥发油总量的80.24%和71.22%。河南南阳艾叶比新疆艾叶含有更加丰富的酚类化合物和挥发油。
[Abstract]:In order to study the relationship between the chemical constituents of Artemisia argyi leaves and its origin, the phenolic compounds and volatile oils of Artemisia argyi from Nanyang of Henan Province and Xinjiang of Xinjiang were used as experimental materials to compare the composition of phenolic compounds and volatile oils. Phenolic compounds were extracted by ultrasonic method using 60% ethanol solution as solvent. The components of phenolic compounds were determined by high performance liquid chromatography (HPLC) combined with standard sample, and the chemical constituents of volatile oil were determined by distillation and extraction combined with gas chromatography-mass spectrometry (GC-MS). The results showed that the volatile oil yields of Nanyang and Xinjiang were 2.6444.0.805, 19 and 14 phenolic compounds were detected in Nanyang and Xinjiang, respectively. The total contents were 13.43 mg/g and 9.75 mg / g, and 29 and 12 compounds were identified in the volatile oil, accounting for 80.24% and 71.22% of the total volatile oil, respectively. There are more phenolic compounds and volatile oils in the leaves of Artemisia argyi than in Xinjiang.
