激光拉曼光谱检测灵芝孢子油

采用激光拉曼光谱分析比较了灵芝孢子油、橄榄油、葵花籽油及鱼肝油的光谱特征，结果显示激光拉曼光谱法可以用于快速检测灵芝孢子油：灵芝孢子油具有位于1 563 cm-1处峰强较弱线宽较宽的特征拉曼峰，而且位于1 445和1 660 cm-1两处拉曼峰的相对强度比与其他油不同。同时运用激光拉曼光谱法分析了变质的灵芝孢子油和廉价的灵芝孢子油，发现暴露在空气中一段时间后的灵芝孢子油的活性成分基本被氧化了，市场上廉价的灵芝孢子油可能是由变质的灵芝孢子油、葵花籽油、或其他廉价植物油混合掺杂而成的。

Raman Spectroscopy Study of Ganoderma Spore Oil

Raman spectroscopy has been applied for rapid analysis of ganoderma spore oil. It is found that the Raman spectrum of ganoderma spore oil has a weak and broad characteristic phonon mode at 1 563 cm-1, which is not observed in olive oil, sunflower seed oil, and cod-liver oil. In addition, the relative intensity ratio of the two phonon modes at 1 445 and 1 660 cm-1 in ganoderma spore oil is very different comparing with that in olive oil, sunflower seed oil, and cod-liver oil. Furthermore, Raman analysis of deteriorated ganoderma spore oil and fake ganoderma spore oil is investigated. Our results showed that when ganoderma spore oil is exposed in air, its active ingredients will be oxidized, and the fake ganoderma spore oil on market could be a mixture of deteriorated ganoderma spore oil, sunflower seed oil, or other cheap vegetable oils.
