Evaluation of Twenty-seven Mineral Elements in Rubus Chingii Hu from Different Growing Areas

OBJECTIVE To evaluate twenty-seven mineral elements in Rubus chingii Hu of different regions.METHODS The content was determined by inductively coupled plasma mass spectrometry.SPSS software was used to conduct comprehensive evaluation through cluster analysis,main component analysis and correlation analysis.RESULTS The 27 elements tested were detected,and 25 elements were detected in all samples,including the average content of K,Mg,Ca,Al,Fe,Mn was high,and the harmful elements in all samples met the limit standard of Chinese Pharmacopoeia.A fingerprint map of the Rubus chingii Hu mineral elements was also established.Clustering analysis showed that there was no significant difference in the mineral element content between the regions.The main component analysis results showed a total of 3 main components analysis,with a cumulative variance contribution rate of 76.0%.The variance contribution of the first main component was 33.2%,where the Ca,Mn,Zn,Mg,K,Fe has a higher load value,a characteristic element of the Rubus chingii Hu.CONCLUSION The method is accurate and repetitive,which provides theoretical basis for Rubus chingii Hu quality evaluation,basic research and resource development and utilization.
