摘　　要：目的基于近红外和主成分分析,建立化橘红快速无损鉴别方法。方法采用近红外光谱技术不经任何化学处理,对原始样品(毛橘红、光橘红、伪品)粉碎后直接检测,获取样品的全部完整的光谱信息,通过聚类分析和主成分分析的模式识别技术对样品进行定性分析,实现了对化橘红的快速无损鉴别。结果化橘红的近红外图谱通过聚类分析和主成分分析能够鉴别出化橘红的优劣。结论近红外光谱法是一种快速、无损鉴别化橘红的方法。OBJECTIVE Establishing a rapid and non-destructive identification method for Citri Grandis Exocarpium based on near-infrared and principal component analysis.METHODS Near-infrared spectroscopy(NIRS)was used to directly detect the original sample without any chemical treatment.The complete spectral information of the sample was obtained.The rapid and nondestructive identification of Citri Grandis Exocarpium was realized by qualitative analysis of samples using pattern recognition technology combining cluster analysis and principal component analysis.RESULTS We can identify the pros and cons of the Citri Grandis Exocarpium by NIRs with cluster analysis and principal component analysis.CONCLUSION The NIRs is a rapid,non-destructive method for identifying Citri Grandis Exocarpium.
