title: [Chemical constituents from Ilex hainanensis].
abstract: OBJECTIVE
  To investigate the chemical constituents from Ilex hainanensis.
  
  
  METHODS
  The compounds were isolated and purified by various chromatographic techniques. The structures were identified by mass and NMR spectral data.
  
  
  RESULTS
  Ten compounds were isolated and identified as Ilexgenin A (1), 3beta, 19alpha-dihydroxyolean-12-ene-24,28-Dioicacid-28-O-beta-D-glucopyranoside (2), Ilexsaponin A1 (3), 2-(Caffeoyloxy) methyl-3-hydroxy-1-butane-4-O-beta-D-glucopyranoside (4), Dibutyl phthalate (5), Rutin (6), Eriodictyol-7-O-beta-D-glucopyranoside (7), Syringaresinol-4-O-beta-D-glucopyranoside (8), (2E) -2-methyl-2-butene-1, 4-diol-4-O-beta-D-(6"-O- caffeoyl) -glucopyranoside (9), 1-O-caffeoyl-(2E) -2-methyl-2-butene-1, 4-diol-4-O-beta-D- glucopyranoside (10), respectively.
  
  
  CONCLUSIONS
  Compound 4, 7 - 10 are obtained from this plant for the first time.
