摘　　要：目的:运用近红外漫反射光谱技术,以标准中药材为样本建立指纹图谱库,对样品进行快速、无损的定性鉴别。方法:分别用三种数据块(原谱、一阶导数光谱、二阶导数光谱)在不同的谱区范围建立了金丝桃、蓝桉、楮实子3种中药材的NIRDRS指纹图谱库,对未知样品进行鉴别。结果:改善了采样技术和标准化数据处理技术之后,3种中药材能够唯一鉴别。结论:NIRDRS指纹图谱库的建立是可行的,该方法能更全面、可靠地反映待测样品的特征信息,具有广泛的应用前景。Objective： To establish fingerprint databases with standard traditional Chinese herbs by NIRDRS and rapidly discrimi- nate the samples. Method： The databases of NIRDRS for Hypericum,Eucalyptus globules and broussonetia papyrifera were established within suitable spectral ranges with three kinds of data block（ original spectrum, first-order derivative spectrum and second-order derivative spectrum ） to discriminate unknown samples. Result： Three kinds of traditional Chinese herbs could be solely discriminated as long as the spectral measurement technique was optimized and the data processing technique were standardized. Conclusion： The establishment of NIRDRS database was feasible. Database technique provided complete and more reliable reflection on the feature.
