OBJECTIVEThe contents of mineral elements in soil and each organ from cultivated and wild Prunella vulgaris were determined in order to provide a theoretical basis for exploitation and protection of wild resources and GAP study.

METHODThe contents of mineral elements (P, K, Ca, Mg, Na, Fe, Cu, Zn, Mn, Al) in soil and each organ from cultivated and wild P. vulgaris were determined by ICP-AES, and the results were analyzed by correlation analysis.

RESULTThe contents of mineral elements in soil and different organs of P. vulgaris were significant different between cultivated and wild species; the contents of P and Cu ranked in the order of spica > leaf > stem, the order of Mg, Ca, Zn, Fe, Mn, Al from high to low was leaf > spica > stem, the concentrations of K, Na were mainly distributed in leaf and stem, less in spica. A distinctly positive correlation between soil and spica for Fe content, and the relationship between soil and leaf, stem were significant positive correlation, the concentrations of Zn in spica, leaf, stem were positively related to soil, K contents in soil and stem were significant positive correlation. The different organs of cultivated and wild P. vulgaris had a strong tendency to accumulate P.

CONCLUSIONThere was no direct relationship between the concentrations of mineral elements in P. vulgaris, and their corresponding soil P. vulgaris adjusts the concentration of mineral elements mainly by active absorption.
