Abstract:

The contents of 19 inorganic elements in different organs (root, stem, leaf, fruit, and seed) of Phyllanthus emblica in dry-hot valley area of Jinsha River were determined by Inductively Coupled Plasma Optical Emission Spectrometer (ICP-OES). The distribution law of the 19 inorganic elements in different organs of P. emblica was studied by one-way ANOVA, correlation analysis, cluster analysis and factor analysis. The results showed that 12 elements (B, Cu, Fe, Mg, Mn, Ni, Zn, Ca, K, Na, P and S) were detected in all P. emblica samples tested. However, Se, Si, Co, Cr, Pb, Cd and Mo were only detected in individual organ samples. The contents of elements B, Cu, Fe, Mg, Mn, Ni, Zn, Ca, K, Na, P, S in different organs were significantly different (P<0.01), and had the characteristics of maximum and minimum values. Significant or extremely significant positive (negative) correlation existed between the contents of the 12 elements. Different organs of P. emblica could be divided into three categories by these 12 inorganic elements (B, Cu, Fe, Mg, Mn, Ni, Zn, Ca, K, Na, P and S). Among them, seed, stem and leaf clustered into the first type, fruit was the second type, and root was the third type. Fe, Na, Zn, Cu, Ca and B were the characteristic elements in different organs of P. emblica. The results indicate that different organs have certain selectivity on the absorption and distribution of different elements, and there are interactions between inorganic elements.
