摘要
目的:对黑龙江省不同产地的北青龙衣样品进行红外指纹图谱分析鉴别研究。方法:采用一维红外光谱结合二阶导数谱、以及相似性比较软件对13个产地的北青龙衣及其主要活性成分胡桃醌的红外指纹图谱进行处理。结果:鉴别出北青龙衣的指纹特征且比较出其不同产地间的差异。其中集贤县、汤原县、海林市青龙衣化学成分含量相对较高,哈尔滨市、桦南县相对较低。结论:对于不同产地北青龙衣,红外指纹图谱分析是一种有效、快速的鉴别分析方法。
Objective： To identify and analyze the infrared fingerprints of fruits of Juglans mandshurica samples from different areas of Heilongjiang province. Method： One-dimensional IR spectrum combined with the second derivative spectrum, as well as similarity comparison software were used to process the IR fingerprints of fruits of J. mandshurica from 13 origins and their main active ingredient juglone. Result： The fingerprint characteristics of fruits of J. mandshurica were identified and their difference between different origins were studied. The content of chemical composition in fruits of J. mandshurica was higher in Jixian county, Tangyuan county, and Hailin, but lower in Harbin and Huanan county. Conclusion： For fruits of J. mandshurica in different origins, infrared fingerprint analysis is an effective and quick method for identification and analysis.
