基于化学计量学结合ICP-MS分析黄花角蒿不同部位元素含量变化
Analysis of elemental content variation in different parts of Incarvillea sinensis using chemometrics combined with ICP-MS
摘要
Abstract
Objective To establish a method for determining the content of 27 inorganic elements in Incarvillea sinensis.Methods The samples of Incarvillea sinensis were pretreated by microwave digestion.The contents of 27 inorganic elements in five parts(root,stem,leaf,flower,and fruit)were determined using inductively coupled plas-ma mass spectrometry(ICP-MS).Origin software was employed for content characteristic analysis,fingerprint analy-sis,heavy metal element analysis,principal component analysis,transfer coefficient analysis,and correlation analysis.Results The variation trends of inorganic element content in Incarvillea sinensis from different origins were general-ly consistent,while significant differences were observed among different plant parts.Among the 27 elements,cal-cium(Ca),magnesium(Mg),aluminum(Al),and iron(Fe)exhibited higher contents,with the leaf part containing the highest levels across all five parts.Incarvillea sinensis demonstrated strong transfer ability for Mg,boron(B),mo-lybdenum(Mo),selenium(Se),and mercury(Hg),but weak transfer ability for chromium(Cr),nickel(Ni),and cadmium(Cd).The correlation coefficients for Fe-Al,titanium(Ti)-Fe,beryllium(Be)-Fe,vanadium(V)-Ti,Be-Ti,and Be-V exceeded 0.98,indicating significant correlations(P＜0.05 or P＜0.01).Conclusion Incarvillea sinensis is rich in inorganic elements,with most heavy metal contents falling within safe limits.The distribution cha-racteristics of elements across different parts are relatively distinct,providing a reference for the development,utiliza-tion,and quality evaluation of its wild resources.关键词
