| 摘 要： | 通过气相色谱-质谱法对不同麝香样品乙醇提取物进行初步定性分析,以判断不同麝香样品的品质。结果表明,天然麝香样品中除含有效成分麝香酮外,还含有多种甾类化合物;而几种市售麝香样品中有些仅麝香酮含量较为显著,几乎不含甾类化合物,其他物质为高级脂肪酸(酯)。通过乙醇提取气相色谱-质谱法可简单、快速、有效鉴定不同麝香的品质。

| Abstract: | A study for the preliminary quality identification of different musk samples by gas chromatography-mass spectrometry (GC-MS) is presented. The musk samples were extracted using ethanol, and then qualitative analysis by GC-MS was carried out for the musk extracts. The results showed that besides active ingredients, muscone in natural musk, there were various steroids in natural musk which could be used as indicators to identify the quality of musk. In some musk samples without steroids, the higher fatty acid-ester was detected. The experiment has proved that GC-MS was an easy, effective and rapid method for quality identification of different musks. |
