title: [A new cardiac glycoside from Periploca forrestii].
abstract: OBJECTIVE
  To study the chemical constituents of Periploca forrestii.
  
  
  METHODS
  The constituents were separate using such various column chromatographic techniques as silica gel, RP-18 silica gel, MCI and Sephadex LH-20. Their structures were identified by such methods as spectral analysis.
  
  
  RESULTS
  Ten compounds were isolated and identified as periforgenin A-3-O-beta-digitoxopyranoside (1), beta-sitosterol (2), periforoside I (3), ursolic acid (4), periplogenin (5), periplocin (6), glycoside E (7), periplocoside M (8) , daucosterol (9), 2alpha, 3alpha, 23-trihydroxy-urs-12-en-28-oic acid (10).
  
  
  CONCLUSIONS
  Compound 1 was a new cardiac glycoside and compound 8 was reported for the first time from this plant.
