摘　　要：本文通过傅里叶变换红外光谱法(FTIR)对大红袍和红花的吸收峰的峰强、峰形、峰位进行了对比研究。研究表明,大红袍和红花的红外光谱图极相似,在3427、2929、2029、1635、1083、642、529cm-1附近均有吸收峰出现且大红袍的强度强于红花,说明二者含有相同或相近的药物成分。根据光谱图看出,两种药物具有其各自的特征峰,这与二者的某些特有功效是相对应的。此外,大红袍为地方性药物,红花为中草药常见药物,此分析为药物大红袍的推广和应用提供了科学合理的依据。Chinese medicines of radix campylotropis hirtella and safflower are studied by Fourier transform infrared spectroscopy （FTIR） and their band intensity, shape and posi- tions are compared. It is shown that radix campylotropis hirtella and safflower have very similar IR spectra and common absorption peaks in 3427,2929,2029,1635,1083,642 and 529 cm^-1, indicating that they contain similar medicinal compositions. However, each drug has its own characteristic absorption peaks, being correlated to its special curative effect. This analysis provides scientific and rational basis for the applications of the local medicine radix campylotropis hirtella and common drug safflower.
