| Abstract: | The contents of 10 mineral elements in Leccinum rugosiceps from five regions were determined by microwave digestion-inductively coupled plasma-atomic emission spectrum (ICP-AES), and the obtained data were analyzed by analysis of variance (ANOVA) and principal component analysis (PCA) using the SPSS software. The results showed that recovery rates from tea standard (GBW 07605) ranged from 91% to 101% and the detection limits were 0.000 1–0.616 5 mg/kg. Mg, Cu, Ca, Na and Zn were more abundant in Leccinum rugosiceps. However, there were significant differences among mushroom samples collected from different regions. PCA showed that the cumulative contribution rate of the first three principal components was 87.87%, which could express most information. Principal component comprehensive scores could reflect the enrichment levels of ten mineral elements in Leccinum rugosiceps from different origins. |
