摘要

目的: 对产自河北、广西、江西、江苏、云南5个产区的枳实样品进行宏观成分的整体鉴别。方法: 采用傅里叶变换红外光谱、二阶导数谱和二维相关谱三级鉴别技术分析5个产地枳实的特征谱峰。结果: 一维图谱中5个产地枳实原粉在400~4 000 cm-1整体峰形较为相似

有7个共有峰

各产区枳实的整体化学成分基本相似

二阶导数谱上云南枳实的特征峰少且钝

江苏、江西的谱峰较多

峰形较尖锐。在二维相关谱上

5个产地枳实形成的峰簇的数目和位置有明显差异。结论: 三级红外光谱的谱学特征可以作为鉴别不同产地枳实的依据。

Abstract

Objective: To compare the differences of the chemical constitutions of Frutus Aurantii Immaturus of different origin Places. Method: By one-dimensional FT-IR spectroscopy

second derivative spectra and two-dimensional related spectral analysis of IR spectra

the features of these spectrum peaks of Frutus Aurantii Immaturus were identified. Result: In one-dimensional map

the raw material of Frutus Aurantii Immaturus from 5 different origins had the similar peak shape among the rang of 400-4 000 cm-1

and 7 common peaks. Frutus Aurantii Immaturus from each origin place had the same chemical content. In the second derivative spectra the characteristic peaks of Frutus Aurantii Immaturus from Yunnan were less and blunter

the more peaks of Frutus Aurantii Immaturus from Jiangsu and Jiangxi were found

and the shapes of peaks were sharp. The two-dimensional related spectral map showed there were obvious differences between the peaks of Frutus Aurantii Immaturus from 5 different origin places. Conclusion: This IR spectra technique can identify Frutus Aurantii Immaturusof different origin places.
