title: [Studies on the chemical constituents of Rubus suavissimus S. Lee].
abstract: OBJECTIVE
  To study the bioactive constituents from leaves of Rubus suavissimus S. Lee.
  
  
  METHODS
  Column chromatography with silic gel was employed to isolate and purify the constituents. Their structures were elucidated by means of IR, MS, NMR and chemical methods respectively.
  
  
  RESULTS
  Two consituents were obtained, which were elucidated as ent-13-hydroxy-kauran-16-en-19-oic acid (I), ent-kaura-16-en-19-oic-13-O-beta-D-glucoside (II), respectively.
  
  
  CONCLUSIONS
  Compound II was seperated from Rubus suavissimus S. Lee for the first time.
