摘　　要：目的采用近红外高光谱成像技术(HSI)鉴别四裂红景天和长鞭红景天。方法采集935~1720nm长鞭红景天和四裂红景天的高光谱图像信息。采用主成分分析法(PCA)和正交-偏最小二乘判别分析法(OPLS-DA)进行分类判别。结果OPLS-DA比PCA分析具有更好的分类性能,HSI和OPLS-DA分析结合可准确识别两种红景天。结论所用方法可快速、无损地鉴别长鞭红景天和四裂红景天,为红景天的品种鉴定、质量控制和评估提供了参考。OBJECTIVE To identify the Rhodiola fastigiata and R.quadrifida by near-infrared hyperspectral imaging(HSI).METHODS HSI information of Rhodiola was collected in the wavelength range of 935 nm to 1720 nm.Principal component analysis(PCA)and Orthogonal partial least squares-discriminant analysis(OPLS-DA)were used for classification.RESULTS OPLS-DA had better classification performance than PCA,and the combination of HSI and OPLS-DA analysis could accurately identify the two Rhodiola species.CONCLUSION This method can quickly and nondestructively identify R.fastigiata and R.quadrifida,which provides reference for species identification,quality control and evaluation of Rhodiola medicinal plants.
