title: Chemical constituents of Allophylus longipes.
abstract: OBJECTIVE
  To investigate the chemical constituents of Allophylus longipes.
  
  
  METHODS
  Compounds were isolated and purified by various chromatographic techniques and their structures were elucidated by physicochemical characteristics and spectral data.
  
  
  RESULTS
  Twenty-five compounds were isolated and identified as cycloart-24-en-3β, 26-diol (1), 3-oxotrirucalla-7, 24-dien-21-oic acid (2), zizyberenalic acid (3), colubrinic acid (4), ent-4(15)-eudesmene-1β, 6α-diol (5), 4(15)-eudesmene-1β, 8α-diol (6), 4(15)-eudesmene-1β, 5α-diol (7), methyl asterrate (8), betulin (9), betulinic aldehyde (10), betulinic acid (11), 3β-hydroxy-5α, 8α-epidioxyergosta-6, 22-dien (12), 3-oxo-19α-hydroxyurs-12-en-28-oic acid (13), ursolic acid (14), scopoletin (15), fraxidin (16), cleomiscosin A (17), 4-hydroxy-3-methoxybenzaldehyde (18), 4-hydroxy-3-methoxycinnamaldehyde (19), 2',6'-dihydroxy-4'-methoxyacetophenone (20), p-(aminoalkyl)-benzoic acid (21), 4-hydroxy-3-methoxybenzoic acid (22), 1-O-p-coumaroylglucose (23), β-sitosterol (24), and poriferast-5-ene-3β, 4β-diol (25).
  
  
  CONCLUSIONS
  All the compounds were isolated from Allophylus longipes for the first time.
