Abstract

The effects of heavy metals, from Hame-Kasi Mine in Western Iran, on the in vitro antibacterial effects of the aqueous extracts of polluted Verbascum speciosum check for this species in other resources Schard. (Scrophulariaceae) flowers in different concentrations were investigated. Determination of heavy metals (Cu, Fe, Mn, and Zn) in collected soils and plants from the control and mine area was performed using Flame Atomic Absorption Spectrophotometry.The control sites were from 5 km distance of the mine. The antibacterial activity of the extracts was examined against 10 bacterial strains (three Gram-positive and seven Gram-negative bacteria). Results showed high Fe, Mn and Zn concentration in polluted soil, and high Fe concentration in polluted plant in compared to control samples. The control and polluted aqueous extract appeared to be highly effective on Salmonella paratyphi check for this species in other resources in different concentrations, but non effective on six other bacteria strains.

Resumen

Se investigó los efectos de los metales pesados provenientes de la mina Hame-Kasi en el oeste de Irán sobre los efectos antibacteriales in vitro de los extractos acuosos florales en diferentes concentraciones del control y contaminado de Verbascum speciosum check for this species in other resources Schard. (Scrophulariaceae). La determinación de los metales pesados (Cu, Fe, Mn y Zn) en suelos y plantas colectados del área de control y de la mina se realizó mediante la espectrofotometría de absorción atómica de llama. Los controles estuvieron a 5 km de la mina. La actividad antibacteriana de los extractos se evaluó contra 10 cepas de bacterias (tres Gram-positivas y siete bacterias Gram-negativas). Los resultados mostraron mayores concentraciones de Fe, Mn y Zn en los suelos contaminados y mayor concentración de Fe en las plantas contaminadas en comparación con las muestras del control. El extracto acuoso del control y del contaminado pareció ser altamente efectivo sobre Salmonella paratyphi check for this species in other resources en diferentes concentraciones, pero no efectiva en las otras seis cepas bacterianas.

Palabras-clave
Metales pesados, Verbascum speciosum, actividad antibacteriana, Mina Hame-Kasi, Irán.
