title: [Study on steroidal compounds from Dioscorea zingiberensis].
abstract: OBJECTIVE
  To study the chemical constituents of Dioscorea zingiberensis.
  
  
  METHODS
  Manifold chromatography methods were used to separate the chemical constituents, and the chemical stuctures were determined by spectral analyses.
  
  
  RESULTS
  6 compounds were isolated from Dioscorea zingiberensis and identified as deltonin, protodeltonin, zingiberensis newsaponin, dioscin, 3-O-[beta-D-glucopyranosyl(1 --> 4)]-beta-D-glucopyranosyl-diosgenin, diosgenin.
  
  
  CONCLUSIONS
  Deltonin and protodeltonin were isolated from this plant for the first time.
