摘　　要：本文采用傅里叶变换红外光谱仪测定了四大种植主产区(安徽、江苏、福建、贵州)的栽培品及河南的野生品,共13个批次太子参甲醇提取物,获得不同产地太子参栽培品的FTIR指纹图谱,并对指纹图谱进行了相似度的计算,同时结合(共有峰率,变异峰率)双指标序列分析方法,对不同产地太子参的FTIR光谱进行了研究。结果表明,该方法所建立的太子参FTIR指纹图谱能够区分栽培品和野生品的差异,双指标序列分析法能够为产区间和产区内太子参品质差异提供参考,两种分析方法结合可为该药材的质量分析、评价与控制提供依据。This work was designed to measure the methanol extracts of 13 batches＇ Pseudostellaria heterophylla [collected from Anhui,Jiangsu,Fujian,Guizou,Henan（wild）] by the Fourier transform infrared spectrometer（FTIR）.The FTIR fingerprint of P.heterophylla was established and calculated with similarity.In addition,the FTIR spectra of different samples were analyzed by the dual-index sequence method（common peak rate and varied peak rate）.The results showed that the cultivated and wild P.heterophylla can be distinguished through the FTIR fingerprint.The dual-index sequence analysis can give references for evaluating differences of samples from different origins.The combination of these two methods can provide a basis for the quality analysis,evaluation,and control of the crude drug.
