title: [Chemical constituents from the aerial roots of Ficus microcarpa].
abstract: OBJECTIVE
  To study the chemical constituents of the aerial roots of Ficus microcarpa.
  
  
  METHODS
  The compounds were isolated and purified by column chromatographic methods on silica gel and Sephadex LH-20. Their structures were elucidated by physicochemical properties and spectral data.
  
  
  RESULTS
  12 compounds were isolated from the 95% ethanol extract. Their structures were idenified as 3beta-hydroxy-11-oxours-12-ene (1), 3beta-acetoxy-11-oxours-12-ene (2), oleanic acid (3), 3beta-hydroxy-oleana-11,13 (18)-dien-28-oic acid (4), betulinic acid (5), pyracrenic acid (6), platanic acid (7), isowigtheone (8), myrsininone A (9), derrone (10), alpinumisoflavone (11) and caffeic acid methyl ester (12), respectively.
  
  
  CONCLUSIONS
  Compounds 4, 6, 12 are obtained from this genus for the first time, compounds 1, 7 - 11 are isolated from this plant for the first time.
