摘要(Abstract):

采用微波消解-电感耦合等离子体发射光谱法(ICP-AES)分别对10个不同居群的明党参植株不同部位及根际土壤中22种矿质元素含量进行测定,分析明党参主要分布区土壤和明党参植株内的矿质元素特征,探讨明党参质量形成机制,为明党参药材质量评价与栽培调控提供依据。结果表明:明党参主要分布区土壤环境质量较好,微量元素含量较高,磷、钾2种常量元素偏低,各分布区之间土壤中矿质元素含量差异较大;硒、磷、钾3种元素在明党参根中有强累积性,不同产地明党参根中矿质元素总含量存在显著性差异;明党参植株不同部位间矿质元素含量差异显著。各主要分布区明党参药材均属于安全级,明党参植株内矿质元素的分布特征可以作为其药材质量评价的指标。
The contents of 22 kinds of mineral elements in different parts of Changium smyrnioides and in the rhizosphere soil of 10 different populations were determined by microwave digestion-inductively coupled plasma atomic emission spectrometry( ICP-AES).The characteristics of mineral elements in the plants and the soil of main distribution area of Ch. smyrnioides was analyzed and the mechanism of the quality formation of Ch. smyrnioides was explored to provide the basis for the quality evaluation and cultivation regulation of Ch. smyrnioides. The results showed that the quality of soil environment was better in the main distribution area of Ch. smyrnioides,the content of trace elements was higher,the contents of P and K were lower and the contents of mineral elements in the soil of each distribution area was significantly different. The three elements of Se,P and K are significantly accumulated in the root of Ch.smyrnioides. There were significant differences in the total contents of mineral elements in the roots of Ch. smyrnioides in different producing areas. The contents of mineral elements in different parts of Ch. smyrnioides were significantly different. Ch. smyrnioides of the main distribution area of Ch. smyrnioides belonged to the safety level,the distribution of mineral elements in the plants can be used as an indicator of the quality of medicinal herbs.
