In the present paper, FTIR was used for obtaining vibrational spectra of untreated Amanitaceae mushrooms harvested in the mountains of Yunnan province, Southwest of China. The results show that the spectra of fruiting body and spore exhibit obvious differences. In the spectra of fruiting body, the strongest absorption band appears at about 1 655 cm(-1), which is described as amide I. There are two strong absorption bands at 1 077 and 1 042 cm(-1) which are assigned to C-O stretching in carbohydrate. The vibrational spectra indicate that the main compositions of the Amanitaceae mushrooms are protein and carbohydrate. The spectrum of spore of Amanita fritillaria shows strong bands at 2 926, 2 855 and 1 747 cm(-1), which can be assigned to the absorption of lipids. The spectra of fruiting body exhibit complicated patterns in the interval between 1 800 and 750 cm(-1), which may be used to discriminate different species of Amanitaceae mushrooms. In addition, FTIR spectral differences were observed between different parts of Amanita manginiana. The result suggests that the chemical constituents are various in different parts of fruiting bodies. It is showed that FTIR spectroscopic method is a valuable tool for rapid and nondestructive identification of Amanita mushrooms.
在本论文中，傅里叶变换红外光谱（FTIR）被用于获取采自中国西南部云南省山区的未处理鹅膏科蘑菇的振动光谱。结果表明，子实体和孢子的光谱呈现出明显差异。在子实体光谱中，最强吸收带出现在约1655 cm⁻¹处，被描述为酰胺I。在1077和1042 cm⁻¹处有两个强吸收带，它们归属于碳水化合物中的C - O伸缩振动。振动光谱表明鹅膏科蘑菇的主要成分是蛋白质和碳水化合物。川贝母鹅膏菌孢子的光谱在2926、2855和1747 cm⁻¹处显示出强吸收带，可归属于脂质的吸收。子实体光谱在1800至750 cm⁻¹区间呈现出复杂的图谱，这可用于区分不同种类的鹅膏科蘑菇。此外，在芒氏鹅膏不同部位之间观察到了FTIR光谱差异。结果表明子实体不同部位的化学成分各不相同。结果表明，FTIR光谱法是一种用于快速无损鉴定鹅膏菌的有价值工具。
