Objective: To investigate the elemental composition of the leaves and flowers of
Catharanthus roseus (C. roseus) due to the plant's wide application in the indigenous
medicinal system and its chemical constituents' importance.
Methods: The atomic absorption spectrophotometer was used for quantitative analysis of
Results: Total 13 important elements were analyzed in leaves and flowers of C. roseus.
Results indicated the presence of Na, K, Ca, Mg, Cr, Fe, Zn, Al, Cu, Ni, Pb, Cd and Mn
in both leaves and flowers. The most important finding of the work was that, leaves of
C. roseus showed high concentration of all elements except K and Zn while flowers of
C. roseus showed higher concentration of K and Zn.
Conclusions: The elemental composition in both leaves and flowers of C. roseus were
found to be different. Therefore, different parts of this medicinal plant are enriched in
some micro and macro nutrients like Fe, Ca, Na, K, Zn, which are very important for
biological metabolic system as well as human health.
