dulteration and substitution are common in commercial samples of many drugs due to resemblance between two or more drugs which are easily mixed with one another giving confounding characters. Consequently, market samples of some of the drugs are available as either completely substituted or a mixed bag of genuine and substituted drugs. In view of regular use of Khulanjan in Unani Medicine and reports of its being admixed with spurious or low quality substitutes, present study was undertaken to study its three samples, two collected from market and one obtained from natural habitat. Pharmacognostical parameters were applied to all the samples to ascertain authenticity of commercially available samples by comparing them with the standard sample. The study consisted of macroscopic, physicochemical and phytochemical studies and spectrophotometery of all the samples. Findings of the study in most of the parameters were found almost similar indicating market samples of the drug to be genuine.
