title: [Study on chemical constituents from twig and leaf of Juniperus sabina].
abstract: OBJECTIVE
  To isolate and determine chemical constituents from twig and leaf of Juniperus sabina.
  
  
  METHODS
  Five compounds were isolated and purified by extraction and different kinds of column chromatography. The structures were determined on the basis of the physicochemical properties and spectral analysis.
  
  
  RESULTS
  The structures were elucidated as quercetin-3-O-(6"-O-acetyl)-beta-D-glucopyranoside(1), hypolaetin-7-O-beta-D-glucopyranoside(2), isoquercetin(3),4-epi-abietic acid(4), beta-sitosterol(5).
  
  
  CONCLUSIONS
  Compounds 1-3 are obtained from Juniperus genus for the first time.
