title: [Studies on the chemical constituents of the seeds from Artabostrys hexapetalus (Annonaceae)].
abstract: OBJECTIVE
  To study the chemical constituents of the seeds from Artabotrys hexapetalus (L.f.) Bhandari (Annonaceae).
  
  
  METHODS
  Various chromatographic techniques were used to separate and purify the constituents. Their structures were elucidated on the physico-chemical properties and spectral data.
  
  
  RESULTS
  Eight compounds were isolated from the seeds of A. hexapetalus. They were identified as four neolignans: isoamericanin A (1), isoamericanol A (2), americanin B (3) and artabotrycinol (4), a semiterpenoid: (R)-artabotriol (5) and others: palmitic acid (6), beta-sitosterol (7) and daucosterol (8).
  
  
  CONCLUSIONS
  Artabotrycinol (4) and (R)-artabotriol (5) are new compounds. Three other neolignans were isolated from this plant for the first time.
