ZHOU Guang-jiao, WANG Chao-qun, QUAN Chun-mei, et al. Correlation Between Quality of Paeoniae Radix Alba in Bozhou and Main Inorganic Elements in Soil[J]. Chinese journal of experimental traditional medical formulae, 2018, 24(18): 76-80. DOI: 10.13422/j.cnki.syfjx.20181507.
Objective: To investigate the correlation between the quality and the contents of inorganic elements in Paeoniae Radix Alba in Bozhou. Method: The contents of nineteen elements
such as Zn
Mn
K
Fe
Ca
Mg
Cu
Cd in Paeoniae Radix Alba were collected from twelve towns in Bozhou
the corresponding soil were determined using inductively coupled plasma mass spectrometry (ICP-MS) and the contents of gallic acid
paeoniflorin and paeonolide were determined by using high performance liquid chromatography(HPLC). In addition
the contents of water-soluble extractives were also determined
and the correlation between them was analyzed by using SPSS 19.0 software. Result: In the twelve towns
Paeoniae Radix Alba had high contents of six kinds of inorganic elements
namely Fe
Mn
Zn
K
Ca and Mg. Among them
the contents of K
Ca and Na were the highest
the contents of Fe and Mn were the second
and the content of Zn was the lowest. The contents of Cr
Hg
Cd and Cu in soil were significantly correlated with the contents of inorganic elements
and the contents of other elements
such as Ca
Al
Ti and Mn
were significantly correlated with other elements in Paeoniae Radix Alba in Bozhou
while other inorganic elements in soil were not correlated. The content of Na in soil had the greatest impact on the quality of Paeoniae Radix Alba in Bozhou
and it was negatively correlated with the contents of gallic acid
paeoniflorin
paeonolide
benzoic acid
benzoyl paeoniflorin and water-soluble extractives. The contents of heavy metal elements were low
which was within the range on the basis of the 2015 Chinese Pharmacopoeia. Conclusion: By analyzing the correlation between the quality and the contents of inorganic elements in Paeoniae Radix Alba in Bozhou and the contents of the inorganic elements in corresponding soil
we can provide basic data and reference for the future choice of production areas and the construction of GAP bases of Paeoniae Radix Alba in Bozhou.
