title: [Studies on chemical constituents of Prunella vulgaris].
abstract: OBJECTIVE
  To study the chemical constituents of Prunella vulgaris.
  
  
  METHODS
  To separate the constituents of P. vulgaris by using various kinds of chromatography and identify their structures on the basis of spectral analysis.
  
  
  RESULTS
  Seven compounds were isolated from the spikes of P. vulgaris. Their structures were established as autantiamide acetate (1), rhein (2), tanshinone I (3), danshensu (4), stigmast-7, 22-dien-3-one (5), 3, 4, alpha-trihydroxy-methyl phenylpropionate (6), butyl rosmarinate (7).
  
  
  CONCLUSIONS
  Compounds 1-4 were isolated from this genus for the first time.
