title: [Studies on chemical constituentsfrom leaves of Acer truncatum].
abstract: OBJECTIVE
  To study the chemical constituents from the leaves of Acer truncatum.
  
  
  METHODS
  Various chromatographic techniques were used to isolate and purify the constituents. The structures of these compounds were elucidated on the basis of spectral analysis.
  
  
  RESULTS
  Seven compounds were isolated and identified as p-sitosterol (1), beta-amyrin (2), beta-amyrin acetate (3), 3, 5-dihydroxy-4-methoxybenzoic acid (4), astragalin (5), quercetin-3-O-beta-D-galactoside (6), and quercetin-3-O-alpha-L-rhamnoside (7).
  
  
  CONCLUSIONS
  All of compounds were isolated from this plant for the first time.
