摘要(Abstract):

利用共有峰率和变异峰率2个指标,以不同产地中药独活样品的红外指纹图谱为标准,计算出所测样品的共有峰率和变异峰率。结果显示4种产自四川的中药独活样品,共有峰率均大于73%,2种产自甘肃样品共有峰率为79.5%,变异峰率仅为12.9%,2种产自湖北样品共有峰率在76.3%,同一产地,种质资源相似,化学成分也非常相似,不同产地,种质资源发生变化,化学成分也会发生相应的变化。傅里叶变换红外光谱法能从整体水平分析谱图特征峰变化规律,可用于探讨不同产地中药独活的种质资源变化以及化学成分变化。
Common and variation peak rates were calculated as dual-index for drug samples based on the infrared spectrogram of Angelicae Pubescentis Radix samples from different places. The results indicated that the common peak rates of 4 samples from Sichuan province,2 samples from Gansu province,and 2 samples from Hubei province were higher than 73%,79. 5% and 76. 3%,respectively. Also,the variation peak rates of 2 samples from Gansu province were lower than 12. 9%. Therefore,there is similar germplasm resources and similar chemical composition in the samples originated from the same place. However,for the samples originated from different places,their germplasm resources and chemical composition maybe have been changed. Fourier transform infrared spectrometry could be used to evaluate the rule of the fingerprint and overview of Angelicae Pubescentis Radix originated from different places by its changes of germplasm resources and chemical composition.
