title: [Chemical constituents of Isodon macrophyllus (II)].
abstract: OBJECTIVE
  To study the chemical constituents of Isodon macrophyllus.
  
  
  METHODS
  Compounds were spearated and purified by silica gel column chromatography and their structures were elucidated on the basis of spectral data and chemical evidences.
  
  
  RESULTS
  Six compounds were obtained from EtOAc extract of leaves of Isodon macroplhllus and identified as rabdophyllin H(I), lushan-ruhescensins F(II), maovecrystal J(III), Taibaijap onicain A(IV), rabdosinate(V), dancostero(VI).
  
  
  CONCLUSIONS
  Co mpounds II-IV were isolated from this plant for the first time.
