Abstract
Pakistan has lush and diverse flora. A comprehensive literature search was conducted to determine the medicinal flowering plants found in Pakistan and they are used as remedies for various disorders or diseases.Certain commonly used medicinal flowers of Karachi were investigated for their elemental composition with the help of Atomic Absorption Spectrometer. Eleven elements Ca, Cd, Cr, Cu, Fe, K, Mg, Na, Ni, Pb and Zn were analyzed. On an average, the quantity of Na was found to be the highest among these flowers (39315.61 ppm) followed by Ca (22490.98 ppm) and K (20751.53 ppm). The average amounts of Zn (99.53 ppm) Cu (17.47 ppm) and Ni (6.20 ppm) were quite low; Cr was detected in lowest quantity (0.17 ppm). The results suggest that these medicinal flowers could potentially be used as raw materials in herbal formulation.
