title: [Interspecific and intraspecific comparison of valepotrates contents in three Valeriana plants].
abstract: OBJECTIVE
  To compare the contents of three valepotrates intraspecifically and intraspecifically in three medicinal Valeriana plants grown in different areas in China.
  
  
  METHODS
  The method of RE-HPLC was adopted.
  
  
  RESULTS
  The results showed that the contents of three valepotriates in Valeriana jatamansi Jones, V. officinalis L. and V. officinalis var. latifolia Miq. were different. Among them, that of Valeriana jatamansi Jones was the highest. The contents of three valepotrates in Valeriana jatamansi Jones varied significantly from different areas, samples collected from Longli of Guizhou province ranking the highest. The contents of three valepotriates in V. officnalis L. also varied significantly from different areas, samples from Liuba of Shaanxi province showing the highest. The results also showed that the contents of three valepotriates in underground part are all higher than that in aerial part.
  
  
  CONCLUSIONS
  The interspecific and intraspecific differences of valepotriates in three Valeriana plans were obvious.
