近年来,随着现代科学技术的发展,中药鉴定技术也在不断发展。愈来愈多的新技术如薄层色谱、电泳技术、紫外光谱、红外光谱的应用,使中药鉴别的专属性得以极大提高。其中的红外光谱,由于特征性强、取样量小、快速,简便、准确等特点,不仅广泛用于西药药品的定性鉴别,用于中药材鉴别方面的研究报道也愈来愈多,从而更加引起人们的重视。本文仅对红外光谱鉴别中药材的原理与方法作一简述。一、红外光谱鉴别中药材的原理
In recent years, with the development of modern science and technology, Chinese medicine appraisal technology is also continuously developing. More and more new technologies such as thin-layer chromatography, electrophoresis, ultraviolet spectroscopy, and infrared spectroscopy have greatly improved the specificity of Chinese medicine identification. Infrared spectroscopy is characterized by its strong characteristics, small sample size, rapidity, simplicity, and accuracy. It is not only widely used in the qualitative identification of western medicines, but also used in the identification of Chinese herbal medicines. People’s attention. This article only briefly describes the principles and methods of infrared spectroscopy in identifying Chinese herbal medicines. First, the principle of infrared spectrum identification of traditional Chinese medicine
