title: Evaluation of Trace Metal Profile inCymbopogon validusandHyparrhenia hirtaUsed as Traditional Herbs from Environmentally Diverse Region of Komga, South Africa.
abstract: FAAS was used for the analysis of trace metals in fresh and dry plant parts ofCymbopogon validusandHyparrhenia hirtaspecies with the aim of determining the trace metals concentrations in selected traditional plants consumed in Eastern Cape, South Africa. The trace metal concentration (mg/kg) in the samples of dryCymbopogon validusleaves (DCVL) showed Cu of 12.40 ± 1.000; Zn of 2.42 ± 0.401; Fe of 2.50 ± 0.410; Mn of 1.31 ± 0.210; Pb of 3.36 ± 0.401 mg/kg, while the samples of freshHyparrhenia hirtaflowers (FHHF) gave Cu of 9.77 ± 0.610; Zn of 0.70 ± 0.200; Fe of 2.11 ± 0.200; Mn of 1.15 ± 0.080; Pb of 3.15 ± 0.100 mg/kg. Abundance of metal concentrations follows the order: Cu > Fe > Pb > Mn > Zn in the flower samples ofCymbopogon validusandHyparrhenia hirtaspecies. The concentrations of trace metals in both plant parts were below the permissible limits (PL) set by WHO. It is suggested that pharmacovigilance be carried out periodically to improve the quality, safety, and efficiency of various herbal products.
