Astragalus is an important traditional Chinese herb that has therapeutic potential in the treatment of diseases. In this study, the dissolution of metallic elements during the material decoction process was investigated using laser-induced breakdown spectroscopy (LIBS). The Ca, Mg, Al, and Fe in the drug residues, liquid, and vapor were selected for the study of the transfer of elements after different decocting times. It was found that the intensities of the spectral lines for these elements in the drug liquid increased with increasing decocting times. The contrast trend was observed in the residues and only calcium was detected in the vapor. Furthermore, the relative mass concentrations of Ca, Mg, Al, and Fe in the liquid were quantitatively determined by a combination of the standard addition method and calibration-free-LIBS method by adding the standard concentration solution of Cu and Cd elements into the drug liquids, it can be found that the maximum error between ...

用LIBS技术分析不同煎煮时间黄芪中金属元素的溶解

黄芪是一种重要的传统中草药，具有治疗疾病的潜力。在这项研究中，使用激光诱导击穿光谱法（LIBS）研究了材料煎煮过程中金属元素的溶解。选择药物残留，液体和蒸气中的Ca，Mg，Al和Fe，以研究不同煎煮时间后元素的转移。已经发现，药液中这些元素的谱线强度随煎煮时间的增加而增加。在残留物中观察到对比趋势，并且在蒸气中仅检测到钙。此外，Ca，Mg，Al的相对质量浓度
