A new convenient and highly sensitive method for micro-amounts detennination of ephedrine with ninhydrin is reported. Details of the working conditions for the method are discussed. The Beer-Lamberts' law is effectively obeyed in ephedrine concentration range of 4-36 ~gJml. The method has also been used for detennination of ephedrine in ephedrine hydrochloride tablets and ephedrine sulphate injections and the results are found consistent.
