Abstract
The present work was carried out to investigate the quantitative determination of crude phytochemicals (alkaloids, flavonoids and saponins), heavy metals and inorganic constituents in Calendula officinale and Sonchus asper. Heavy metals were determined by atomic absorption spectrophotometer and inorganic constituents by the available methods (AOAC, 2000). The studied plants showed variable amount of phytochemicals, heavy metals and inorganic constituents. In case of heavy metals, Pb, Fe, Cu, Zn, Ni and Ag were recorded. The amount of inorganic constituents was also found in considerably different levels. The study is of particular importance for providing a scientific data base line.
