Rauwolfia serpentina is an important medicinal plant widely used in formulating various drugs and medicines in the pharmacological industries. The efficacy of the medicinal plants mainly depends upon its constituents like nutrients and trace metals that require their detection with sophisticated techniques having cost-effective, fast data acquisition and multi-elemental detection capability. Therefore, the aim of this study is to investigate the elemental profile of the leaf and seed of the Rauwolfia serpentina plant using direct current arc optical emission spectroscopy. The emission spectrum of the powder of the leaves and seeds of the Rauwolfia serpentina has been acquired in the spectral region 300–900 nm at a resolution of 0.3 nm. The spectrum shows the persistent lines of the calcium, potassium, sodium, iron, magnesium, manganese, molybdenum, nickel, chromium, cadmium, aluminum, titanium, bismuth, mercury, lead, tin, barium, vanadium, silicon and strontium, which confirms the occurrence of these elements in the leaf and seed. Area of the spectral profile evaluated by curve fitting has been used for comparing the content of elements present in leaf and seed of Rauwolfia serpentina. The role of the detected elements has been described with reference to human health.

直流弧光发射光谱法对蛇形非洲狼蛛（Sarpagandha）叶和种子的元素评估

蛇形紫花菊是重要的药用植物，广泛用于配制药理学行业中的各种药物。药用植物的功效主要取决于营养成分和微量金属等成分，这些成分需要使用具有成本效益，快速数据采集和多元素检测能力的先进技术进行检测。因此，本研究的目的是使用直流弧光发射光谱法研究蛇纹紫杉植物叶片和种子的元素分布。蛇蝎叶和种子的粉末的发射光谱已在300-900 nm的光谱区域中以0.3 nm的分辨率获取。光谱显示出钙，钾，钠，铁，镁，锰，钼，镍，铬，镉，铝，钛，铋，汞，铅，锡，钡，钒，硅和锶的持久线，这证实了这些元素在叶片和种子中的出现。通过曲线拟合评估的光谱分布面积已被用于比较蛇纹紫薇叶片和种子中元素的含量。已经参考人类健康描述了所检测元素的作用。
