The present studies were carried out to investigate the physiochemical and minerals analysis of the two varieties of mentha grown in Khyber Pakhtunkhwa-Pakistan. The proximate composition was determined according to standard official approved methods. The highest proximate values moisture 6.5±1.0% (stem), ash 10±2.0% (leaves), fat 2.4±0.5% (leaves), fiber 10±0.5% (stem) and protein 5.5±2.0% (leaves) of Mentha piperita citrate were found. Flame Photometer and Atomic Absorption Spectrometric techniques were applied for the minerals analysis. Na, K, Mg, Cu and Mn, were highest in leaves of M. piperita citrate. While maximum quantity of Fe and Zn were determined in leaves of M. piperita perpeta, P and Cr were not found in any varieties parts.
