从白蚁散白蚁中分离得到一种荧光生物碱去甲哈尔烷，其结构经1H NMR、UV/维斯、质谱和气相色谱/质谱表征。微线圈1H NMR光谱允许从质量有限的材料中获得光谱，便于鉴定去甲哈尔烷，这是白蚁在紫外光下荧光的主要成分。去甲哈尔烷均匀地存在于约1纳克/毫克的散白蚁tibialis银行工人，士兵，和有翅类;散白蚁flavipes（Kollar）工人;和散白蚁virginicus（银行）工人。观察到一些白蚁发出强度较低的荧光，但未检测到去甲哈尔烷水平的差异。机制，可能占荧光的差异进行了讨论，是可能的生态影响去甲哈尔烷白蚁。
The fluorescent alkaloid norharmane has been isolated from Reticulitermes termites and characterized by 1H NMR, UV/Vis, mass spectrometry, and gas chromatography/mass spectrometry. Microcoil 1H NMR spectroscopy allowed spectra to be obtained from mass-limited material, facilitating the identification of norharmane, which is the major component in termite fluorescence under UV light. Norharmane was uniformly present at approximately 1 ng/mg in Reticulitermes tibialis Banks workers, soldiers, and alates; Reticulitermes flavipes (Kollar) workers; and Reticulitermes virginicus (Banks) workers. Some termites were observed to fluoresce with less intensity, but no differences in norharmane levels were detected. Mechanisms that may account for fluorescent differences are discussed as are the possible ecological implications of norharmane in termites.
