title: [Compounds from roots of Chirita fimbrisepala Hand.-Mazz].
abstract: OBJECTIVE
  To study the chemical constituents the roots of Chirita fimbrisepala.
  
  
  METHODS
  The constituents were extracted with solvent, separated and purified with chromatographic methods, identified by NMR, MS, UV, IR and physical-chemical constants.
  
  
  RESULTS
  Three flavonoids mahuangchiside(I), hispidulin (II) and kaempferol(III) were isolated with daucosteral(IV).
  
  
  CONCLUSIONS
  I is a new compound elucidated as hispidulin-7-O-beta-D-xylopyranosyl-(1-->2)-beta-D-xylopyranoside, named mahuangchiside, II and III were isolated for the first time from the family Gesneriaceae, and IV was isolated for the first time from the genus Chirita.
