title: [Studies on the chemical constituents of Phlomis younghusbandii].
abstract: OBJECTIVE
  To study the chemical constituents of Phlomis younghusbandii.
  
  
  METHODS
  Compounds were isolated from the ethanolic extract by silica gel column chromatography, and their structures were identified by physical and chemical evidences and spectral methods.
  
  
  RESULTS
  Eight compounds were isolated and identified respectively as 8-acetylshanzhiside methyl ester (1), shanzhiside methyl ester (2), phlomiol (3), 2-butoxy-2-(hydroxymthyl) tetrahydro-2H-3,4,5-pyrantriol (4), sesamoside (5), pulchelloside-I (6), luteolin-7-O-beta-D-glucopyranoside (7) and daucosterol (8).
  
  
  CONCLUSIONS
  All the compounds were isolated from the plant for the first time.
