title: [Studies on chemical constituents in herb of Centella asiatica].
abstract: OBJECTIVE
  To study the chemical constituents from Centella asiatica.
  
  
  METHODS
  Chemical constituents were isolated by repeated column chromatography (Toyopearl HW-40C and HPLC) and their structures were elucidated on the basis of spectroscopic method.
  
  
  RESULTS
  Five compounds were identified as: docosyl ferulates (1), bayogenin (2), 3beta-6beta-23-trihydroxyolean-12-en-28-oic acid (3), 3beta-6beta-23-trihydroxyurs-12-en-28-oic acid (4), D-gulonic acid (5).
  
  
  CONCLUSIONS
  All of the Compounds were isolated for the first time from C. asiatica.
