Mephedronehydrochloride (4-methylmethcathinone. HCl / 2-(methylamino)-1-(p-tolyl) propan-1-one hydrochloride) adulterated with monosodium glutamate (Ajinomoto) were detected and confirmed by very simple and accurate Raman spectroscopy. Further adulteration ratio was determined by solubility differences of mephedrone and ajinomoto in methanol. The recovery of each component were obtained efficiently, thus this study provides simple and effective method of recognition and judgment of composition of mephedrone and ajinomoto
