本文采用傅里叶变换红外光谱方法(FTIR)对中药材重楼及其伪品开口箭的红外光谱进行了测试及对比分析。研究表明,重楼和开口箭各自有其独特的红外光谱特征,二者各自所包含的红外吸收峰的峰位明显不同,二者的红外光谱的峰形整体上有非常明显的区别,特别是在1650cm-1处及1405～1258cm-1范围这两个地方二者的峰形有非常明显的区别。采用傅里叶变换红外光谱方法可对重楼及其伪品开口箭加以鉴别和区分。 In this paper, Fourier transform infrared spectroscopy (FTIR) was used to test and compare the infrared spectra of the open arrowheads of the reticulata and its counterfeit goods. The results show that the re-building and the opening arrow have their own unique infrared spectral characteristics, the two contain the peak of the infrared absorption peak was significantly different, the two peak shape of the infrared spectrum as a whole has a very significant difference, especially There is a very significant difference between the peak shapes at 1650 cm-1 and 1405 cm-1258 cm-1. Using Fourier transform infrared spectroscopy method can be re-floor and its counterfeit open arrows to identify and distinguish.
