title: [Studies on the chemical constituents of Ampelopsis humulifolia var. heterophylla (Thunb.) K. Koch].
abstract: OBJECTIVE
  To study the chemical constituents from Ampelopsis humulifolia var. heterophylla (Thunb.) K. Koch.
  
  
  METHODS
  Chromatography and spectroscopic analysis were employed to isolate and elucidate the chemical constituents in the plant.
  
  
  RESULTS
  Six compounds were isolated and elucidated as lupeol, beta-stiosterol, daucosterol, ethyl gallate, gallic acid and catechin.
  
  
  CONCLUSIONS
  The six compounds were isolated from this plant for the first time.
