不同金莲花药材的IR鉴别研究

Identification Study of Different Flos Trollii by IR

目的:建立不同金莲花药材的红外光谱鉴别方法,为对其科学评价与品质鉴定提供新技术。方法:采用FTIR图谱直观-选点归一法。结果:10个金莲花药材的FTIR吸收峰的峰形、峰位及峰强度存在一定的差异。结论:金莲花药材可用IR图谱直观分析-选点归一法进行鉴定,为研究影响中药质量因素的鉴别特征提供了新的方法。

Objective： To establish a method to identify different Flos Trollii with IR spectra and to provide a new technique for their science estimation and quality identification. Mehtods ： Their IR spectra were obtained by the method of intuitionistic analysis-selecting point to normalization. Results ： Differences on the shape, the position, the height and the relative intensity of absorption peaks were shown in IR spectra of the ten samples. Conclusions： Different Flos Trollii can be identified using IR spectra obtained by the method of intuitionistic analysis-selecting point to normalization. This new method can be used to study the identification features of the influence factors of Traditional Chinese Medicine quality.
