title: [Chemical constituents contained in Macropanax rosthornii].
abstract: OBJECTIVE
  To study active constituents of Macropanax rosthornii in treating rheumatoid arthritis.
  
  
  METHODS
  Silica gel column chromatography, preparative HPLC and modern spectrum techniques were applied for a systematic study on chemical constituents contained in M. rosthornii.
  
  
  RESULTS
  Twelve compounds were separated from M. rosthornii and identified as serratagenic acid (1), serjanic acid (2), betulinic acid (3), 6beta-hydroxy-3-oxo-olean-12-en-28-oic acid (4), 3-O-alpha-L-arabinopyranosyl serratagenic acid (5), 3-O-alpha-L-arabinopyranosyl serratagenic acid-29-methyl ester (6) , 3-O-alpha-L-arabinopyranosyl serratagenic acid-28-O-beta-D-glucopyranosyl ester (7), scopoletin (8), beta-sitosterol (9), daucosterol (10), 3,4-dihydroxybenzoic acid (11), and stearic acid (12).
  
  
  CONCLUSIONS
  Above compounds are separated from M. rosthornii for the first time.
