摘要(Abstract):

目的:对夜关门的显微特征及其微量元素含量进行测定,为其开发和研究提供理论依据。方法:采用显微鉴别的方法,对夜关门的根、茎、叶、种子的组织结构进行鉴别,同时利用微波消解技术-电感耦合发射光谱(ICP-OES)法对其Ca、K、Mg、Zn、Sn、Cu、Pb、As、Hg、Cd、Mn、Fe、Ag、Al、Ba、Ga、Mo、Ge、Co、Sb、Ni、Cr等元素进行含量测定。结果:鉴定出黔产夜关门的显微特征,且夜关门中含有丰富的微量元素,元素含量由高到低依次为K、Ca、Mg、Ag、Fe、Al、Mn、Zn等元素,精密度试验的RSD为0.244%~2.681%,回收率89.9%~107.0%。结论:黔产夜关门符合截叶铁扫帚的显微特征,重金属元素及微量元素的含量均符合《药用植物及制剂进出口绿色行业标准》,为黔产夜关门的综合开发利用及质量控制提供了科学依据。
Objective: To systematically study the Microscopic features and detect the microelement content of Guizhou Lespsdeza,which provide theoretical basis for future development and research of Guizhou Lespedeza. Methods: To use microscopic identification method to identify the tissue structure of the roots,stems,leaves and seeds of Guizhou Lespsdeza. and microwave digestion technology-inductively coupled emission spectroscopy( ICP-OES) method to detect the content of its Ca,K,Mg,Zn,Sn,Cu,Pb,As,Hg,Cd,Mn,Fe,Ag,Al,Ba,Ga,Mo,Ge,Co,Sb,Ni,Cr,etc respectively according to the " Green Industry Standards for Import and Export of Medicinal Plants and Preparations". Results: Identified the microscopic features of Guizhou Lespedeza,And it contained rich microelement. The order of element content from high to low was: K,Ca,Mg,Ag,Fe,Al,Mn,Zn and so on. The RSD of the precision test was from 0. 244% to 2. 681%,and the recovery rate was from 89. 9% to 107. 0%. Conclusions: The microscopic features of Guizhou Lespedeza are in line with Lespedeza cuneata,the content of heavy metal elements and microelement is in line with the " Green Industry Standard for Import and Export of Medicinal Plants and Preparations". It provides a scientific basis for the comprehensive development and utilization and quality control of Guizhou Lespedeza.
