荧光法是根据中药的某些成分在紫外光下能产生荧光的性质进行鉴定。《中国药典》1990年版一部收载的509种植物药材中,有64种规定了荧光法鉴别,其它均未作此规定。1991年初,我们对全区所属中药材公司、医院中药房、中医院等34家单位进行了20种中药饮片的考核评比工作。考核中,查出伪品4种、掺伪1种。前4个品种的真伪在性状上极易混淆,在药典未作荧光法规定的情况下,为了找出较明显的区别方法,笔者将考核后的检品留样作了荧光观察,发现这四品种的真伪在紫外光下大多数都具有荧光,而且容易区别,现将观察结果介绍如下:
Fluorescence is based on the nature of certain components of traditional Chinese medicine that can produce fluorescence under UV light. Of the 509 plant herbs listed in the 1990 edition of the Chinese Pharmacopoeia, 64 were regulated by the fluorescence method, and others did not. In early 1991, we conducted evaluation and appraisal of 20 Chinese Herbal Medicine Pieces in 34 companies in the region, including Chinese herbal medicine companies, hospital pharmacies, and Chinese medicine hospitals. During the assessment, four types of counterfeit products and one type of adulteration were identified. The traits of the first four varieties are easily confusing. In the case of the pharmacopoeia without the fluorescence method, in order to find out the obvious difference method, the author made a fluorescent observation of the sample after the examination and found that The authenticity of the four varieties is mostly fluorescent under ultraviolet light, and it is easy to distinguish. Now the observation results are described as follows:
