Resumo
Instrumental neutron activation analysis (INAA) has been applied
to multielemental determinations of medicinal extracts obtained
from the plants. Cordia Verbenacea DC, Folidago Microglossa DC, and
Petivefia Alliacea.
Concentrations of the elements A1, Br, Ca, C1, Co, Cs, Fe, K, La,
Mg, Mn, Na, Rb, Sb, and Zn have been determined in dried extracts
of these herbs by short and long irradiations under a thermal neutron
flux of 10n-1013n/cm2s in the IEA-R1 nuclear reactor. The NBS Tea
Leaves (1572) and NIES Pepperbush (1) reference materials were
analyzed simultaneously with the plant extracts.
The results obtained in these analyses have shown a good accuracy
and reproducibility of the method. The relative errors and the
relative standard deviations were less than 10% for most of the
elements analyzed.
