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.
