荧光法鉴别中药材具有实用、快速、操作方便等优点,根据中药材与混淆品产生的荧光不同而得以区分。一般观察荧光的紫外光波长为365nm,如果用短波254nm时,应指明,因为两波长下的荧光现象不同。笔者整理了21种中药材与其混淆品的荧光鉴别,(?) Fluorescence identification of traditional Chinese medicine has the advantages of practicality, rapidness, and convenient operation, and can be distinguished according to the different fluorescence produced by Chinese herbal medicines and adulterants. Generally, the fluorescence wavelength of the ultraviolet light is 365 nm.
