title: [Studies on chemical constituents from herbs of Botrychium lanuginosum].
abstract: OBJECTIVE
  To study the chemical constituents of Botrychium lanuginosum.
  
  
  METHODS
  Various chromatographic techniques were used to isolate and purify the constituents. The structures were elucidated by chemical evidence and spectroscopic methods.
  
  
  RESULTS
  Ten compounds were isolated from the 95% ethanol extract of the herb of B. lanuginosum and their structures were elucidated as 30-nor-21beta-hopan-22-one (1), beta-sitosterol (2), luteolin (3), thunberginol A (4), apigenin (5), (6'-O-palmitoyl)-sitosterol-3-O-beta-D-glucoside (6), daucosterol (7), 1-O-beta-D-glucopyranosyl-(2S, 3R, 4E, 8Z)-2-[(2R-hydroxy hexadecanoyl) amino]-4, 8-octadecadiene-1, 3-diol (8), luteolin-7-O-glucoside (9), sucrose (10).
  
  
  CONCLUSIONS
  Compounds 1-10 were isolated from this genus for the first time.
