title: Oreganum vulgare Linn. leaf: An Extensive Pharmacognostical and Phytochemical Quality Assessment.
abstract: OBJECTIVE
  Standardization and detailed pharmacognostical studies of Oreganum vulgare Linn. leaf for authentication and commercial utilization.
  
  
  METHODS
  Oreganum vulgare Linn. leaf was with standardization according to standard procedures described in WHO, 2011 and I.P. 1996.
  
  
  RESULTS
  The physicochemical parameters total ash, acid insoluble ash, water soluble ash and sulphated ash were found to be 11.5%, 11%, 5, 10.5% w/w respectively. Foaming index was found be <100. The trace elements were found to be copper, lead, cadmium, zinc, cobalt, manganese, nickel and copper in ethanol extract and phytochemical screening of aqueous and ethanol extract showed the presence of carbohydrates, flavonoids, anthocyanins, phenolic compounds etc.
  
  
  CONCLUSIONS
  The standardization parameters viz. physico-chemical parameters, macroscopy, microscopy, taxonomy, anatomy and preliminary phytochemical screening, microbial and aflatoxin count, HPTLC profile is being reported to help in authentication and development of monograph of this plant.
