Abstract: Phytochemicals are primary or secondary constituent depending on their role during metabolism in plant. The study investigated the quantitative characterization of phytochemicals present in leaves of Justicia carnea. Phytochemical screening of Justicia carnea was done using high performance liquid chromatography (HPLC) and gas chromatography (GC). The quantitative phytochemical screening of leaves of Justicia carnea indicated in descending order the presence of phytoconstituents; 744.24mg/100g (tanic acid), saponin 449.43mg/100g (Justisci-saponin-1 and sapogenin), sterols 30.58mg/100g (Sitosterol and Campesterol), , glycoside 39.27mg/100g (Kaemaferitrin and 0-sistosterol-3-B-glycoside) , terpenoids 8.55 x 10-1mg/100g (Beta-amyrin and Alpha-amyrin) , oxalate 102.11ppm and phytate 12.36ppm. Leaves of Justicia carnea contain different phytochemicals with different therapeutic potentials which could serve as precursors in the synthesis of drugs as well as herbal agents in treatment of diseases. Keywords: Justicia carnea, phytoconstituent, ethnomedicinal, chromatography.
