Accumulation dynamics of elements in Panax notoginseng during its whole
Panax notoginseng is a valuable traditional medicine in China, which
could stanch the blood, disperse gore and reduce the pain caused by
blood diseases. Understanding the accumulation dynamics of elements
during the growth of PN is conducive to guiding rational fertilization
in production. In this study, 17 elements (B, Na, Mg, Al, P, K, Ca, Cr,
Mn, Fe, Co, Ni, Cu, Zn, Mo, Cd, and Pb) in PN from different periods
were determined by ICP-OES and ICP-MS. The result showed that the change
of element accumulation in different periods was consistent with the
growth rule of PN. Element content in leaves and roots differed during
the same period. Therefore, according to the changes of element content
in different periods, scientific fertilization can be carried out to
improve the quality and yield of PN. Besides, to study the accumulation
characteristics of Panax in the same place, 17 elements in P.
vietnamensis, P. stipuleanatus and P. bipinnatifidus were also
determined by ICP-OES and ICP-MS. The result showed that P. vietnamensis
and P. stipuleanatus exhibited more similar in elements than the P.
notoginseng and P. bipinnatifidus. HCA and PCA analysis found that
different Panax species can be distinguished based on element content.
