The objective of this study was to determine the concentrations, potential sources and evaluate the risks of heavy metals in selected plants from Awash River Basin, Ethiopia. A total of 57 samples were analyzed from four different plant species. Microwave-assisted digestion was applied to digest the samples and the concentration of nine elements namely: Al, Cr, Ni, Cu, Zn, As, Cd, Hg, and Pb were analyzed using Inductively Coupled Plasma-Mass Spectrometry (ICP- MS) (Thermos X SERIES2).

Introduction: Lung cancer is one of the most common cancers worldwide. In certain countries such as United States of America, it is the leading cause of related cancer mortality among both men and women. Natural products play an important role in overcoming the limitations of chemotherapy and radiotherapy.

Background: Worldwide particularly in developing countries, a large proportion of the population is at risk for tropical parasitic diseases. Several medicinal plants are still used traditionally against protozoal infections in Yemen and Saudi Arabia. Thus the present study investigated the in vitro antiprotozoal activity of twenty-five plants collected from the Arabian Peninsula.

The present research study deals with the evaluation of sixty four methanolic and aqueous extracts of thirty Yemeni plants used in traditional medicine for their in vitro antiproliferative activity against three human cancer cell lines in a microtiter plate assay based on cellular staining with crystal violet, for their antimicrobial activity against antibiotic susceptible three Gram-positive, three Gram-negative bacterial and one fungal stains and three multiresistant Staphylococcus strains by the agar diffusion method and the determination of MIC against three Gram-positive bacteria with the broth micro-dilution assay, as well as for their antioxidant activity using the DPPH radical scavenging method. Furthermore the chemical composition of the methanolic extracts was determined by using chromatographic methods. As a result of this work, 12 Yemeni herbs namely Centaurothamus maximus, Costus arabicus, Cupressus sempervirens, Dichrocephala integrifolia, Euphorbia schimperi, Gomphocarpus fruticosus, Kanahia laniflora, Meriandera benghalensis, Pulicaria inuloides, Solanum glabratum, Tarconanthus camphoratus and Vernonia leopoldii demonstrated a noteworthy growth inhibitory effect against all cancer cell lines with IC50 values <50 microg/ml.
