Abstract:

The levels of As, Cd, Pb and Hg were investigated in the medicinal herbal syrup Entoban, which is widely used in the management of non-specific diarrhea and acute intestinal infections of various etiologies. The ingredients in Entoban syrup include 6 potent herbal drugs: Aegle marmelose, Berberis aristata, Butea frondosa, Holarrhena antidysenterica, Myrtus communis, and Quercus infectoria. Entoban medicinal plant syrup was analyzed for As, Cd, Pb and Hg by flame atomic absorption spectroscopy (FAAS). Contents of heavy metals in the examined samples were in the range: As (0.074–10.0 ppm); Cd (0.020–0.3 ppm); Pb (0.00–10.0 ppm) and Hg (0.00–1.0 ppm). Results were compared with permissible limit acceptability intake (AHPA). According to determined amounts of heavy metals, the investigated Entoban syrup samples were validated and considered safe for human consumption.

Key words: Heavy metals, Flame atomic absorption spectroscopy, Medicinal plants, Entoban syrup
