利用傅里叶变换红外光谱技术对长柄鹅膏菌、粗鳞白鹅膏菌、格纹鹅膏菌、红黄鹅膏菌、黄柄鹅膏菌、灰疣鹅膏菌、欧氏鹅膏菌、小豹斑鹅膏菌进行傅里叶变换红外光谱研究,发现八种鹅膏菌的傅里叶变换红外光谱极为相似,特征区和指纹区(1800～1100cm-1)的相关系数均大于0.966。因此从这八种鹅膏菌的原始光谱对其鉴别将十分困难。通过差谱技术处理后,八种鹅膏菌在1800～1100cm-1范围呈现出各自的特征,相关分析结果定量反映出它们之间差异较为明显。利用差谱中特征区和指纹区的差异可快速鉴别出该八种鹅膏菌。研究表明:傅里叶变换红外光谱技术能提供大型真菌所含化学成分的分子结构信息,结合差谱技术可以鉴别同属下的不同种高等真菌。
Using Fourier transform infrared spectroscopy techniques, the effects of auricula auricula, glabra amanita, amanita amanita, red amanita, yellow amanita, gray warts amanita, Euclid The results showed that the Fourier transform infrared spectra of eight kinds of amanita were very similar, and the correlation coefficients between characteristic area and fingerprint area (1800 ~ 1100cm-1) were all greater than 0.966. Therefore, it is very difficult to identify the eight kinds of amanita original spectrum. After treatment by the differential spectrum technique, the eight kinds of amanita showed their own characteristics in the range of 1800 ~ 1100cm-1. The correlation analysis quantitatively reflected the obvious difference among them. The eight species of amanita can be quickly identified by using the difference between the characteristic region and the fingerprint region in the differential spectrum. The results show that Fourier transform infrared spectroscopy (FTIR) can provide the molecular structure information of the chemical constituents contained in the macrofungi, and the differential spectroscopy technique can identify different species of higher fungi in the same genus.
