【摘要】 设计了中药材红外光谱阵列相关系数比对软件,在建立红外光谱数据库的基础上,依未知药材与库药材光谱的比对,可自动鉴别未知药材。研究结果表明:指定阵列相关系数的阈值,抓住特征波段光谱的比对,可避开CO2和H2O等外界因素对谱图的干扰,使比对结果准确可靠,该法可作为中药鉴别的常规方法。更多还原

【Abstract】 The software of a correlation coefficient array of FTIR spectroscopy was designed. Based on the fingerprint infrared spectrum database of Chinese herbs, an unknown herb can be identified automatically according to the comparison of the unknown herb’s spectrum with spectrum in the database. The result of the study shows that the factors which disturb spectrum experiment, such as H2O, CO2 etc. , can be avoided through assigning threshold values of correlation coefficients and comparing spectra with characteristic peak bands, and the comparison result is credible and correct. The method will be used as a conventional method for identifying Chinese herbs.更多还原
