Abstract
Objective: To investigate the correlation between soil mineral elements and NIR fingerprint of Angelica sinensis.
Methods: The fingerprint of 130 batches of Angelica sinensis from 12 production regions were determined by near infrared spectra with integrating sphere and diffuse device of near infrared spectrometer. The determination of 15 kinds of mineral elements in the corresponding origin of soil mass fraction were determined by atomic absorption spectrometry or inductively coupled plasma mass spectrometry, grey correlation analysis and multivariate nonlinear regression method were used to analyze.
Results: The soil mineral elements and their contribution were Cu > Pb, which were the main influencing factors of Angelica sinensis NIR fingerprint maximum absorbance on peak 7 249cm-1; the contribution of mineral elements in soil were Cr > Fe > Zn > Cd > Ca on peak 6 996 cm-1,there were positive correlation between Cr and Cd, and negative correlation between Fe and Ca; on peak 5 900 cm-1were Cu; on peak 5 000 cm-1were K > Ca > Zn; on peak 4 762 cm-1were K > Sb; on peak 4 651 cm-1were Ca > K > As > Cr, there were positive correlation between Ca and K, and the positive correlation or negative correlation between the square of As and Cr; the contribution of mineral elements in soil on peak 4 545cm-1were Ni > Cu > As; on peak 4 347 cm-1were Cd > Ca > As > Fe > K > Sb, and there were positive correlation among Cd, K, As and Fe.
Conclusion: Angelica sinensis NIR fingerprint spectrum characteristics associate with a variety of soil mineral elements, which show the multiplicity and interactivity.
目的:探讨土壤矿质元素与当归近红外指纹图谱的相关性。方法:采用近红外光谱仪积分球扩散装置对12个产地130批当归药材进行近红外指纹图谱分析。采用原子吸收光谱法或电感耦合等离子体质谱法测定土壤质量分数中相应来源的15种矿质元素，并采用灰色关联分析和多元非线性回归分析方法进行分析。结果:土壤矿质元素Cu > Pb是影响当归近红外指纹图谱7 249cm-1峰最大吸光度的主要因素;土壤矿质元素在6 996 cm-1峰上的贡献为Cr > Fe > Zn > Cd > Ca, Cr与Cd呈正相关，Fe与Ca呈负相关;峰5900 cm-1为Cu;5 000 cm-1峰K > Ca > Zn;4762 cm-1峰上K > Sb;4 651 cm-1峰Ca > K > As > Cr, Ca与K呈正相关，As与Cr的平方呈正相关或负相关;4 545cm-1峰土壤矿质元素贡献为Ni > Cu > As;4 347 cm-1峰Cd > Ca > As > Fe > K > Sb, Cd、K、As和Fe呈正相关。结论:当归近红外指纹图谱特征与多种土壤矿质元素相关，表现出多样性和交互作用。
