摘要
【目的】对2个以上中草药样品进行定性评价,以阐明不同产区间的相似程度,为中药材真伪鉴定和品质评价奠定基础。【方法】利用共有峰率和变异峰率2个指标,以不同臭灵丹样品的红外指纹图谱为标准,计算出所测样品相对于标准品的共有峰率和变异峰率。按照共有峰率的大小,建立了不同的共有峰率和变异峰率双指标序列方法。【结果】文中指纹图谱显示,臭灵丹不同产区样品间最大共有峰率为93.33%,最小共有峰率为38.89%,变异峰率最大为114.29%,最小为0.00%。【结论】红外指纹图谱中的共有峰率和变异峰率在一定程度上能反映出不同产区臭灵丹的相近情况,为臭灵丹的进一步研究提供了理论依据。
[ Objective] Qualitative evaluation of more than two Chinese medicinal herbs samples was studied to clarify the similarity level among the samples from different areas, which provided foundation for authenticity identification and quality evaluation of Chinese medicinal herbs. [ Method ] Using the common peak rate and the variation peak rate methods, the standard samples of them were calculated based on the infrared fingerprint of the different Laggera pterodonta samples. According to the figures of the common peak rate, the different common peak rate and mutation peak rate of dual-index sequential analysis method were established. [ Result] The fingerprint spectral implicated that the maximum common peak rate was 93.33 %, while the minimum was 38.89 %, the maximum mutation rate was 114.29 % and the minimum was 0.00 % for different areas of Laggera pterodonta. [ Conclusion] The common peak rate and the variation peak rate in the infrared fingerprints could reflect the similarity of Laggera pterodonta in different areas, which provided a theoretical basis for the further study of the Laggera pterodonta.
