Applied Analytical Methods for Detecting Heavy Metals in Medicinal Plants

Impact of Heavy Metal Pollution in the Environment on the Metabolic Profile of Medicinal Plants and Their Therapeutic Potential

“…Understanding the mechanisms by which medicinal plants absorb and accumulate heavy metals is vital for ensuring the safety and efficacy of herbal remedies [ 93 ]. Regular monitoring of heavy metal levels in both medicinal plants and the surrounding environment, coupled with sustainable cultivation practices, can help mitigate the risks associated with heavy metal contamination in medicinal plants [ 94 ]. This knowledge contributes to the development of guidelines and regulations to safeguard the quality and safety of herbal medicines.…”

Atomic spectrometry update: review of advances in the analysis of clinical and biological materials, foods and beverages

“…Concern over contamination by PTEs in medicinal plants , which have been a major source of drugs for hundreds, if not thousands, of years, means that concentrations of these elements must be monitored. The relevant literature over the past 25 years has been reviewed (206 references with titles), 9 to provide an understanding of the current situation regarding the concentrations of PTEs in medicinal plants, but also to develop an in-depth awareness of the main methods of analysis. The review covered the important topic of sample preparation, including the possibilities for direct analyses of solids, before dealing with each instrumental technique.…”

Luminescent metal–organic frameworks as optical sensors for selective sensing towards Fe3+ and Cu2+

“…Generally, iron and copper ions are widely present in the human body and the environment, and thus, it is quite important for the specific detection of these two ions. Up to now, the traditional techniques, such as atomic absorption or emission spectrometry (AAS/AES), inductively coupled plasma mass spectrometry (ICP-MS), 8 anodic stripping voltammetry, and capillary electrophoresis, often require precise instrumentation or complicated sample preparation procedures. Compared to other analytical approaches, luminescence detection strategy not only offers ease of acquisition but also exhibits remarkable advantages in terms of sensitivity, selectivity, response time, and in situ detection capabilities, with wide applications in biochemistry, medicine, chemical industry, and domains over recent years.…”
