【摘要】 为全面了解关黄柏药材及产区土壤无机元素含量特征,在关黄柏基源植物黄檗的分布区内设置31个样点,采集药材及土壤样本,测定两者中钠(Na)、镁(Mg)、磷(P)、硫(S)、钾(K)、钙(Ca)、锰(Mn)、铁(Fe)、锌(Zn)等9种无机元素的含量并进行分析。关黄柏药材中Ca(10级)和Zn(3~9级)的含量较高,其余元素的含量较低(1~2级);不同产地药材中各无机元素的含量相对稳定;各产区土壤无机元素含量差异不显著,分析表明其与药材中无机元素的含量无相关性。关黄柏药材中各无机元素的相对含量具有较强的规律性,以此建立的指纹图谱可用于药材鉴定;土壤中无机元素的含量对药材中无机元素的含量无显著影响。更多还原

【Abstract】 To find the content characteristics of inorganic elements in Phellodendri amurensis Cortex and thesoil of production area, the content of nine inorganic elements of 31 medicinal materials and 31 soil samplesfrom 31 distribution plots of Phellodendron amurense Rupr., which are mainly distributed in Heilongjiang,Jilin, Liaoning and Beijing, were detected and analyzed, including Na, Mg, P, S, K, Ca, Mn, Fe and Zn.According to the study, the content of each inorganic element from different regions was relatively stable, whilethe contents of Ca(10 level) and Zn(3-9 level) were higher than the other inorganic elements(1-2 level) inPhellodendri amurensis Cortex referred to the content level of inorganic elements in herbs. On statistics, therewas no obvious difference of inorganic elements contents among all soil samples, while there was no pertinenceof inorganic elements contents in soil with that in medicinal materials. For a deeper analysis, notable regularitywas discovered in the content of these inorganic elements from medicinal materials, based on which afingerprint was established for identification and quality evaluation of Phellodendri amurensis Cortex. Thestudy also showed the content of inorganic elements in soil had no significant effects on those in medicinalmaterials.更多还原
