Determination and Analysis of Heavy Metals of Paridis Rhizoma from Different Localities and Pieces
To analyze and determine heavy metal content in Paridis Rhizoma from different genus and localities
in order to provide a reference for selecting cultivation areas and establishing the quality standard of Paridis Rhizoma of heavy metals content.
Method:
2
Microwave digestion method combined with inductively coupled plasma atomic emission spectrometry method (ICP-AES) method were applied to determine the contents of 6 heavy metals
i.e. As
Cu
Hg
Cd
Pb and Cr in 39 samples of Paridis Rhizoma of different genus and localities in Yunnan Province. Cluster analysis
statistical analysis and principal component analysis (PCA) were used to compare the differences of heavy metals contents in different localities and species.
Result:
2
The contents of six heavy metals in Paridis Rhizoma met the ISO international standard of
Heavy Metal Limit of Traditional Chinese Medicine
-
traditional Chinese Medicinal Materials
. Under the limited value standard of
Green Trade Standards of Importing Medicinal Plants and Preparations
the over-standard rate of heavy metal As was 15.4%
the excess rate of Cd was 5.1%
and the excess rate of Pb was 2.6%. The contents of Cu and Hg conformed to relevant requirements. Cluster analysis
statistical analysis and principal component analysis showed that for the same variety
differences in producing places had significant effects on heavy metal content
while differences in species had little effects.
Conclusion:
2
The results of this study indicated that the heavy metal content of
Paris
planted in and around Dali basically conformed to relevant standards. The differences of heavy metal content in
Paris
were mainly regional differences
which provided a theoretical basis for standardizing the cultivation of medicinal materials and formulating the limit standards of heavy metals for Paridis Rhizoma.
