摘　　要：利用傅里叶变换红外光谱法(FTIR)研究了人工栽培与野生的毛头鬼伞,及其液化前后的菌盖样品。毛头鬼伞的红外光谱主要由蛋白质、多糖的特征吸收峰组成。人工菌与野生菌的光谱差异表现为蛋白质和多糖的特征峰强度比,野生菌的多糖特征吸收峰要比人工菌的吸收峰明显。菌盖液化黑色物与液化前的菌盖光谱相比,多糖特征峰明显减弱,表明菌褶液化现象主要是多糖的变化。红外光谱结果为毛头鬼伞的进一步的开发研究提供了参考信息。In the paper, Fourier transform infrared （FTIR） spectroscopy was used to study the fruiting body of wild growing and cultivated Coprinus cornatus and the cap of the mushroom before and after deliquescing into inky liquid. The results show that the infrared spectra of Coprinus cornatus are mainly composed of the absorption bands of protein and polysaccharide. Remarkable differences are observed in the absorption bands of polysaccharide between the spectra of the wild growing and cultivated mushrooms, by which the＇wild growing and cultivated Coprinus cornatus can be discriminated. It was also found that the absorption bands of polysaccharide become weaker obviously in the black-inky samples of deliquescing cap compared with the un-deliquescing cap, indicating that the polysaccharides in the cap of Coprinus cornatus are transformed during the process of cap deliquescing into a black, inky liquid. The spectral results can offer useful information for a further study of Coprinus cornatus.
