摘　　要： 为了实现对中药粉末掺假现象的快速鉴别,有效地控制中药粉末的质量,引入光谱成像分析技术,以中药黄连和黄柏的混合粉末为例进行检测。首先以中国药品生物制品检定所提供的黄连、黄柏对照药材为参照,分别构建黄连和黄柏的光谱成像指纹图谱,进而分析二者指纹图谱的差异,提取特征波段。将质量各为1 g的两种粉末混合,采集混合粉末检品的光谱图像,依据两种中药粉末的光谱特征,采用波段比重构光谱图像,并采用域值法进行图像分类。分类结果实现了对检品的鉴别,同时得到检品的空间分布状态。鉴别结果表明光谱成像分析技术是一项有望解决掺假中药粉末鉴别难题的技术,且检测过程无损、快速。 In order to identify the adulteration of traditional Chinese medicine（TCM） powder quickly and control the quality of TCM powder effectively,spectral imaging analysis technology is used to test the mixed powder of rhizoma coptidis and cortex phellodendri chinensis.The standard samples of rhizoma coptidis and cortex phellodendri chinensis applied by National Institute for the Control of Pharmaceutical and Biological Products are used to construct the fingerprintatlas.After analyzing the differences of two fingerprints,the characteristic wave bands are obtained.Take 1 g of rhizoma coptidis powder and cortex phellodendri chinensis powder respectively,and mix them.The spectral images of mixed powder are captured.The spectral images are reconstructed with band ratio method and classified with threshold method.The technology realizes the identification of mixed powder and obtains the spatial distribution of samples.The results show that the spectral imaging analysis technology can resolve the problem of TCM powder adulteration and that the testing process is nondestructive and rapid.
