Abstract
Purpose: To evaluate the content of
trace elements in Galium incanum SM. subsp. centrale
Ehrend.
Methods: The air-dried aerial parts
of the plant material were used and its water extract (2
% w/v infusion) was analysed for trace elements using
x-ray fluorescence (XRF ) spectrometry.
Results: The aqueous extract
depicted significant concentrations of macro- and
micro-nutrients with heavy metal and metal oxide content
of 4.07 - 6.02 and 3.19 - 4.01 % for powdered plant
material and water extract, respectively. The contents
of Ca (22840 ppm) and K (8204 ppm) were the highest
among all the elements while Zn (45.9 ppm) and Fe (328
ppm) were also detected in significant amounts. Zn, Mn
and Cu showed the highest content while those of Mg,
Al, K, Ca, Fe and P lowest in the water extract.
Conclusion: The presence of significant
levels of Ca, K, Na, Fe, Zn, Mg, Mn and Cu in G. incanum
subsp. centrale showed that this plant has notable
nutrient elements. The traditional use of Gallium
species as a diuretic may be attributed to its rich
content of potassium.
