摘要(Abstract):

目的 :建立一种符合甘草自身特点的红外指纹图谱分析方法。方法 :利用 2个指标 :共有峰率 ,变异峰率 ,分别以各甘草样品的红外指纹图谱为标准 ,计算其他样品相对于该标准样品的共有峰率和变异峰率 ,并按照共有峰率的大小建立不同的序列。结果与结论 :利用共有峰率和变异峰率双指标序列分析法可以对 2个或多个不同品种、不同产地甘草样品进行方便可靠的鉴别。
Objective: To investigate a new method for the analysis of IR fingerprint spectra of Radix Glycyrrhizae. Method: Two indexes, common peak ratio and variation peak ratio, are used to compare the IR spectra of various Radix Glycyrrhizae samples, and the values are calculated by means of sequent analysis. Result and Conclusion: The dual-index sequence method provides a good approach to discriminate Radix Glycyrrhizae samples of different species and geographical origins.
