摘要
Swertia chirayita 是用于治疗多种疾病的最重要的药用植物之一。本研究利用一种新兴的非破坏性激光诱导击穿光谱(LIBS)技术,对獐牙菜(Swertia chirayita)植物进行了成分分析。通过光发射研究,证实了 Mg、Ca、K、Fe、Sr、Cr 和 Na 为必需元素,而 Al、Ti、Si、Ba、Mn 和 Li 为非必需元素。利用波尔兹曼图技术和星界展宽参数,计算出等离子体温度和电子数密度的范围分别为 (10,000-12,000) K ±1000 K 和 (1.5-1.8) × 1017 cm-3。最后,利用免校准(CF-LIBS)分析法进行了成分分析,并将结果与 ICP-MS 进行了比较。结果表明,钙和铁的浓度高于其他检测到的元素。所有有毒元素都在安全范围内。因此,这种药用植物可用于治疗因缺乏这些元素而引起的各种疾病。
Compositional analysis of Swertia chirayita medicinal plant using laser-induced breakdown spectroscopy and ICP-MS.
One of the most significant medicinal plants used to treat numerous illnesses is Swertia chirayita. The present study demonstrated the compositional analysis of the Swertia chirayita (S. chirayita) plant using an emerging and non-destructive laser-induced breakdown spectroscopy (LIBS) technique. Mg, Ca, K, Fe, Sr, Cr, and Na were verified as necessary elements by the optical emission investigations, while Al, Ti, Si, Ba, Mn, and Li were non-essential. Using the Boltzmann plot technique with stark broadening parameters, plasma temperature and electron number density were calculated in the range of (10,000-12,000) K ±1000 K and (1.5-1.8) × 1017 cm-3, respectively. Finally, compositional analysis was carried out using calibration-free (CF-LIBS) analysis and results were compared with ICP-MS. It was observed that the concentration of Ca and Fe is higher than other detected elements. All the toxic elements are found to be within the safe limit. So, this medicinal plant can be used to cure a variety of diseases that arise due to the deficiency of these elements.
