title: [Studies on chemical constituents of root tuber of cultivated Pseudostellaria heterophylla (Zheshen No. 1)].
abstract: OBJECTIVE
  To study the chemical constituents of the cultivated Pseudostellaria heterophylla (Zheshen No. 1) as a traditional Chinese medicine, and provide a scientific basis for its quality evaluation.
  
  
  METHODS
  The chemical constituents were isolated by silica gel column chromatography and structurally elucidated by analysis of their physicochemical characteristics including spectroscopic data.
  
  
  RESULTS
  Thirteen compounds were obtained and identified as taraxeryl acetate (1), taraxerol (2), stigmast-7-en-3beta-ol(3), beta-sitosterol (4), daucosterol (5), stigmast-7-en-3-O-beta-D-glucopyranoside (6), dihydroferulic acid [3-(4-hydroxy-3-methoxyphenyl) propionic acid] (7), adenosine (8), uridine (9), alpha-ethyl-D-galactopyranoside (10), 3-furfuryl pyrole-2-carboxylate (11), glucose (12), and sucrose (13), respectively.
  
  
  CONCLUSIONS
  Compounds 1, 2 and 7-10 were isolated from the root tuber of P. heterophylla for the first time.
