abstract: OBJECTIVE
  To study the chemical constituent from the antithrombus activity extract of Radix Aerio Fici Microcarpae.
  
  
  METHODS
  The isolation and purification of the extract were conducted by means of silica gel column chromatography, polyamide column chromatography and recrytallization. The structures of these compounds were elucidated based on the physicochemical properties and spectroscopic analysis.
  
  
  RESULTS
  7 compounds were isolated from the extract. They were identified as isovanillic acid (1), 4-hydroxybenzoic acid(2),3,4-dihydroxybenzoic acid (3), friedelane (4), alpha-amyrin acetate (5), lanosterol (6) and beta-sitosterol (7) .
  
  
  CONCLUSIONS
  Compound 3,4 and 7 are isolated from this plant for the first time.
