“…Additionally, the correlation coefficient of the linearity was represented by the r 2 values. The limit of detection (LOD) and limit of quantification (LOQ) were analyzed using a blank solvent ( n = 20); the LOD had an standard deviation (SD) of 3 and the LOQ had an SD of 10 (Filipiak‐Szok, Kurzawa, & Szłyk, 2015). All the test samples were analyzed in triplicate.…”

Bupleuri Radix is a famous traditional Chinese medicine (TCM) and an important raw material in TCM patent prescriptions. It is widely used in several countries, including China, Japan, South Korea, and America. However, the impact of heavy metal transfer rules on TCMs remains unknown. In this study, a total of 45 paired original medicines (OMs), decoction pieces (DPs), and vinegar‐processed (VPs) samples were simultaneously determined via inductively coupled plasma‐mass spectrometry after a microwave digestion. The concentrations of the elements were shown at three levels: (a) Al and Fe at the mg/g level; (b) Pb, Cu, Ba, Mn, Cr, and Ni at the mg/kg level; (c) Co, As, Cd, and Hg at μg/kg level. It is worth noting that the Cu levels were found to exceed the maximum concentration set by Chinese legislation (20.0 mg/kg). In addition, Mn, Ni, and Cu levels were higher in samples from the Gansu province than those from other provinces. The accumulation of the heavy metals decreased in the order of OMs > DPs > VPs; this was especially true for the Al and Fe levels. Furthermore, the results indicate that decocting the samples may reduce the intake of heavy metals. The element transfer ratios for decoctions were under 50% compared to herbal medicines and decreased in the order of Co > As > Mn > Hg > other metals. Our study strongly suggests that long‐term and regular monitoring for heavy metals in the plant is necessary.

“…[4][5][6] However, these products need a better quality control 7 due to the presence of potentially toxic and essential (macro and micro) elements, which can have harmful effects when their intake significantly exceeds the recommended amounts in herbs. [8][9][10][11] For most of the analytical determinations from several biological samples, sample digestion is required. The selection of the optimum method for sample pretreatment is based on specific parameters, such as concentration of the analyzed metals, nature of the sample (solid, liquid, etc.)…”

In this study, the elemental composition of nine medicinal plants and phytomedicines was evaluated by using axial view inductively coupled plasma optical emission spectrometry (ICP OES) after three digestion procedures: dry ashing (DA) and two wet digestions with a mineral acid (HNO 3 /H 2 O 2 ) mixture on a conventional hot plate (CD), besides microwave digestion (MW). Accuracy was assessed from spinach leaves (CRM 1570a) and recovery values were in the range of 82 to 113.8%. Precisions, such as relative standard deviation (RSD), below 10% were reached. The MW procedure was preferred for its accuracy (recovery values of 94 to 102%), reduced contamination, increase in the efficiency of the decomposition process, lower residual acidity and reduced time required for digestion. The concentrations of analytes in the samples (minimummaximum in μg g ). The levels of Al, Ba, Cd, Cr, Mo, Pb, Se and V in all investigated samples were found to be below the limit of detection of ICP OES. The multielement analysis by ICP OES showed that the method is simple, fast and reliable for the multielement determination in medicinal plants and phytomedicines.
