Comparative study of the composition of the macro- and micro-nutrients in the leaves of synadenium grantii hook with the tolerable upper intake levels for children, adolescents, pregnant woman and female

The aim of studies was to compared 14 minerals in Synadenium grantii leaves used in the treatment of human diseases with tolerable upper intake levels (ULs) for children, adolescent, pregnancy and female. Concentrations of minerals in samples were determined using induction coupled optical emission spectrometry and the results also were compared to values of FDA and WHO for children, adolescents, pregnancy and female. Comparative results showed that according to UL, the elements Na, P, Cu, Fe, Mn and Zn in Synadenium grantii leaves does not represent a risk of adverse health effects. The concentration of Mo is below of limit set by UL only children (4-8 years), adolescent, pregnancy and female. Leaves of these plants accumulate Cr above limit of FAO. The concentration of Ni is high and can be harmful as it exceeds the UL per day. The content of Mo is above the UL for tolerable intake level for children aged 1-3 years. The value Cd obtained is above the guidelines established by the WHO. For elements such as potassium, cadmium, chromium, silicon, cobalt and aluminum, the present study showed that there are gaps regarding knowledge of the levels in which nutrients can be ingested (UL), especially for children, adolescents and pregnancy and female.
