[Study on the correlation between the quality of Cornus officinalis and the contents of the inorganic elements in the planting soil].
OBJECTIVE
To analyze the correlation between the quality of Cornus officinalis and the contents of the inorganic elements in the planting soil.


METHODS
The contents of 11 kinds of inorganic elements including Zn, Mn, K, Fe, Mg, Ca, Cu, Cd, As, Pb and Hg in Cornus officinalis and the planting soil were determined; The contents of loganin, ursolic acid, polysaccharides, tannins, organic acid, water-soluble extractives and ethanol-soluble extractives in Cornus officinalis were determined; The correlation between the quality of Cornus officinalis and the contents of the inorganic elements in the planting soil was analyzed.


RESULTS
There was no significant difference in the content of chemical components of Cornus officinalis produced in the three main areas. The contents of loganin and water-soluble extract complied with pharmacopoeial provisions. Especially, inorganic elements of Fe, Mn and K had significant effects on the quality of Cornus officinalis.


CONCLUSIONS
The results provide the foundation for the selection of cultivating area and the reference for standard cultivation of Cornus officinalis.
