Resumen:
The determination of trace elements in Hypericum perforatum leaves and flowers, their teas, tinctures and tablets was carried out by
Electrothermal Atomic Absorption Spectrometry (ETAAS) and Ultrasonic Nebulization System coupled to Inductively Coupled Plasma
Optical Emission Spectrometry (USN-ICP-OES). Hypericum perforatum (St. John?s wort), is a phytomedicine used for the treatment of
depression. Samples were collected from different sources in the argentinian market. Heavy metals contents in the investigated samples
were found at different levels. Chromium and cobalt were undetectable above their limits of detection in both liquid and solid samples;
while aluminum, cadmium, lead, iron and vanadium were present in the majority of samples.
The analytical results obtained for all metals indicate that they were present at concentration well below the acceptable daily intake
recommended by the World Health Organization. Based on the results obtained in the present work, it is concluded that the present
techniques are suitable for the routine determination of heavy metals concentration in phytopharmaceuticals.
