title: [Study on quality specification of Rhizoma et Radix Valeriana Jatamansi].
abstract: OBJECTIVE
  To provide scientific basis for the utilization and development of Valeriana jatamansi by setting up the quality control specification of V. jatamansi.
  
  
  METHODS
  The pharmacognostical methods were applied. The extract of V. jatamansi was examined. Moisture and ash were determined. And the bioactive constituents were analyzed by TLC and HPLC.
  
  
  RESULTS
  The morphological and histological characters of V. jatamansi were observed. Content of total ash, acid-insoluble ash, and moisture of 15 samples from different habitats and times were determined. The qualitative and quantitative analysis of valtrate and acevaltrate by TLC and HPLC were preformed respectively.
  
  
  CONCLUSIONS
  The established method can be used for the quality control of V. jatamans.
