title: [Chemical constituents from Astilbe myriantha].
abstract: OBJECTIVE
  To study the chemical constituents from Astilbe myriantha.
  
  
  METHODS
  The constituents were isolated and purified by column chromatography methods and recrystallization. Their structures were identified on the basis of physiochemical properties and special analysis.
  
  
  RESULTS
  Ten compounds were isolated from 95% ethanol extract of Astilbe myriantha and their structures were identified as: beta-sitosterol (1), methyl p-hydroxy benzoate (2), ferulic acid (3), bergenin (4), gallic acid (5), (+)-catechin (6), 3beta-acetoxy-6beta-hydroxyolean-12-en-27-oic acid (7), 3beta-hydroxyolean-12-en-27-oic acid (8),3beta,6beta-dihydrolean-12-en-27-oic acid (9) and 3beta-hydroxyurs-12-en-27-oic acid (10).
  
  
  CONCLUSIONS
  Compounds 1-7 are isolated from this plant for the first time.
