Tukhm-e-Konch (Mucuna pruriens) belongs to the family Fabaceae. It is also known as Velvet bean. It is a prime drug of Unani Medicine commonly used in the treatment of impotence, diabetes mellitus, bones fractures, cough, dog bite, cancer and madness. Due to natural variations a number of natural products have significantly different biological activity and varied clinical efficacy. Therefore, it becomes essential to standardize the herbal drugs to ensure their identity, quality and purity so as to ascertain their therapeutic efficacy. In the present study an attempt has been made to determine the physicochemical characters helpful in identification, standardization and quality control of Tukhm-e-Konch. It includes the parameters used in National Unani Pharmacopeia i.e. Total Ash values, Acid insoluble ash, Water soluble ash, successive extractive values , loss of weight on drying at 105ºC , pH at 1% & 10%, bulk density (poured & tapped density) and moisture content. Qualitative analysis and Chromatographic study (TLC) were also performed.
