Heavy metal (Hg, Ar, Cr, Cd, Pb) and trace element (K, Se, Zn)
composition of stem bark of Stereospermum colais was evaluated with
flame atomic absorption spectrometry (FAAS). Estimation of heavy
metals was performed using hydride generation technique (cold vapour
atomic absorption spectrometry) and in which carrier gas was nitrogen.
The results obtained revealed the presence of trace elements and heavy
metal was within the limit showing the safe use of the bark of
Stereospermum colais as herbal drug for various treatments like
cancer, arthritis etc.
