title: [Phenolic components from herbs of Dendrobium aphyllum].
abstract: OBJECTIVE
  To study the phenolic constituents of Dendrobium aphyllum.
  
  
  METHODS
  Various chromatographic techniques were used to isolate and purify the constituents, their physico-chemical properties and spectral data were employed to elucidate their structures.
  
  
  RESULTS
  Nine bibenzyls and two benzylethanyl compounds were isolated and identified as: moscatilin (1), gigantol (2), batatasin (3), tristin (4), 3, 5, 4'-trihydroxylbibenzyl (5), 3, 5-dimethoxyl-4, 4'-dihydroxylbibenzyl (6), moscatin (7), 2, 4, 7-trihydroxyl-9, 10-dihydrophenanthrene (8), hircinol (9), 2-(4-hydroxyphenyl) ethyl-beta-D-glucopyranoside, salidroside (10) and p-hydroxylbenzylacetic acid (11).
  
  
  CONCLUSIONS
  All compounds were obtained firstly from the plant, and the compounds 10 and 11 were isolated in this genus for the first time.
