灵芝孢子油与6种其他植物油中的脂肪酸组分的比较

对灵芝孢子油与菜籽油等6种植物油的脂肪酸组成相似性进行分析,同时探讨了红外光谱法鉴别灵芝孢子油的可行性。采用气相色谱法对灵芝孢子油及菜籽油等6种植物油脂肪酸进行了测定,并利用傅里叶变换红外光谱仪对其信息进行采集。市售不同品牌灵芝孢子油,脂肪酸组成比较接近。脂肪酸组分聚类分析结果显示,灵芝孢子油的脂肪酸组成与菜籽油最相似,其次为花生油和橄榄油。利用1397.4 cm~(-1)、967.1 cm~(-1)、913.7 cm~(-1)处吸收峰,红外光谱法可以将灵芝孢子油与菜籽油、大豆油、玉米油、葵花籽油和橄榄油区别开来。红外光谱法可以将灵芝孢子油与菜籽油等植物油区别开来,这为灵芝孢子油鉴别提供了一种快速有效的途径。

Fatty Acid Composition of Spore Oil from Ganoderma lucidum: A Comparison with Six Other Vegetable Oils

This study analyzed the composition similarity of fatty acids between spore oil from Ganoderma lucidum and six different vegetable oils, and discussed the possibility to indentify the Ganoderma lucidum spore oil using infrared spectroscopy. The composition of fatty acids of Ganoderma lucidum spore oil and six other vegetable oils were analyzed by gas chromatograph (GC). And their infrared spectra informations were collected by fourier transform infrared spectrometer. The fatty acids composition among different commercial brands of Ganoderma lucidum spore oils were close. Hierarchical clustering analysis based on the composition of fatty acids showed that spore oil from Ganoderma lucidum was most similar to rapeseed oil, followed by peanut oil and olive oil. Using the absorption peak at 1397.4 cm-1, 967.1 cm-1 and 913.7 cm-1, infrared spectroscopy can distinguish Ganoderma lucidum spore oil from other vegetable oils. The characteristic of infrared spectroscopy that can distinguish these spore oils from other vegetable oils provides a fast and effective way for Ganoderma lucidum spore oil authenticity identification.
