title: [Phenylethanoid glycosides from root of Picrorhiza scrophulariiflora].
abstract: OBJECTIVE
  To study the phenylethanoid glycosides from root of Picrorhiza scrophulariiflora.
  
  
  METHODS
  Column chromatographic techniques were used for isolation and purification of chemical constituents of the plant and the structures were identified by spectroscopic analysis.
  
  
  RESULTS
  Six phenylethanoid glycosides were isolated and elucidated as: 2-(3,4-dihydroxyphenyl)-ethyl-O-beta-D-glucopyranoside (1), 2-(3-hydroxy-4-methoxyphenyl)-ethyl-O-beta-D-glucopyranosyl (1-->3) beta-D-glucopyranoside (2), scroside B (3), hemiphroside A (4), plantainoside D (5) and scroside A (6), respectively.
  
  
  CONCLUSIONS
  Compounds 1, 2, 4 and 5 were isolated from this plant for the first time and compound 2 was firstly obtained from natural source.
