title: [Study on the chemical constituents of Phryma leptostachya].
abstract: OBJECTIVE
  To study the chemical constituents of Phryma leptostachya.
  
  
  METHODS
  The chemical constituents were isolated and purified by silica gel column, recrystallization and Pre-RP-HPLC and their structwes were elucidated by spectroscopic methods.
  
  
  RESULTS
  Five compounds were obtained and identified as ursolic acid (1), quercetin (2), isovanillic acid (3), p-hydroxybenzoic acid (4), adenine arabinoside (5).
  
  
  CONCLUSIONS
  Compounds 2 - 5 are isolated from this genus for the first time.
