Okra is known by different local names in different countries. Since okra has very interesting nutritional properties, it has attracted research. In the present study, attention has been paid to investigate the nutrients it holds that are essential for a healthy body. Flame absorption spectrophotometer was used to ascertain Ca, Cr, Cu, Fe, Mg, Mn, Pb, and Zn content. The amount of calcium was found highest at 4582.85 mg/kg, 1067.23 mg/kg and 1816.37 mg/kg in raw pod flesh, unripened seeds and ripened seeds, respectively. Pb and Cr were not detected at all, while the highest value of nitrogen (4.32%) was found in unripened pods.
Momordica charactia lin( Bitter melon) has been the interest of many studies by researchers for a long time due to its very interesting human beneficial properties. It belongs to cucurbitacea family and momordica genus. It is used by human consumption all over the world in different forms such as a vegetable and /or medicine. The researchers have concentrated on the studies on its fruits and some times on its seeds and leaves. The present study is an extensive investigation of the quantitative elements such as Ca, Cd ,Co, Cr, Cu, Fe, Mg, Mn, Pb, Zn, K, N, and P of the fruit- skin, fruit-flesh, fruit-seed, tissue skin, leaf and root of the momordica charantia lin using flame atomic absorption spectrometry. The result shows a quite good variation of the concentration of the elements in different part of the plant.
