title: [Secondary metabolites of Gliocladium sp., a growth accelerating fungus for Anoectochilus roxburghii (Wall.) Lindl].
abstract: OBJECTIVE
  To study the secondary metabolites of fungus Gliocladium sp. that helps accelerate the growth of A. roxburghii.
  
  
  METHODS
  Compoud isolation by chromatography and structure elucidation by chemical and spectral analyses.
  
  
  RESULTS
  Five compounds were obtained and elucidated as: 8(E)-N-(2'-hydroxypalmityl)-1-O-beta-gly-copyranosyl-3-hydroxyl-9-methyl-2- octodecanine-4, 8-diene (I), N-(2'-hydroxytetracosanoyl)-1,3,4-trihydroxy-2-octodecanine(II), 7, 22-diene-3-hydroxy-6,9-epidioxyergosta(III), ergostol(IV) and alpha-palmitin(V).
  
  
  CONCLUSIONS
  I, II, III were obtained from Gliocladium sp. for the first time.
