title: [Chemical Constituents from Salvia przewalskii Root].
abstract: OBJECTIVE
  To study the chemical constituents of the root of Salvia przewalakii.
  
  
  METHODS
  The chemical constituents were isolated and purified by means of chromatographic techniques and their structures were elucidated by spectroscopic methods.
  
  
  RESULTS
  17 compounds were isolated and identified as danshenxinkun B (1), danshenol C (2), isotanshinone (3), 1,2-dihydroisodihydrotanshinone-I (4), isotanshinone-II A (5), dihydrotanshinone-I (6), tanshinlactone (7), danshenol B (8), tanshinone-I (9), danshenspiroketallactone (10), ferrugino (11), epi-danshenspiroketallactone (12), danshenxinkun A (13), sapriolactone (14), 12-hydroxy-6,7-secoabieta-8,11,13-trien-6,7-diol (15), 6α-hydroxysugiol (16) and hypargenin B (17).
  
  
  CONCLUSIONS
  Compounds 1 - 8 are isolated from this plant for the first time.
