title: Standardization of Rajanyādi cūrṇa: An ayurvedic preparation.
abstract: BACKGROUND
  Rajanyādi cūrṇa (RC) is an ayurvedic classical preparation used in the treatment of digestive disorders, fever, jaundice, anemia, and asthma. We seek to standardize this drug to ensure its quality.
  
  
  OBJECTIVE
  The current investigation was aimed at the preparation of cūrṇa in three batches so as to standardize it.
  
  
  METHODS
  The cūrṇa was prepared in-house in three different batches according to directions given in The Ayurvedic Formulary of India. The cūrṇa was evaluated based on organoleptic characters, physical characteristics, and physico-chemical parameters. High performance thin layer chromatography was carried out for the quantification of curcumin.
  
  
  RESULTS
  The parameters were found to be comparable and sufficient for the evaluation of the cūrṇa.
  
  
  CONCLUSIONS
  Ayurvedic medicine, RC has been standardized using the various parameters and can be incorporated while developing the pharmacopoeial standards.
