title: [Chemical constituents from the aerial part of Sibiraea angustata].
abstract: OBJECTIVE
  To study the chemical constituents from the aerial part of Sibiraea angustata.
  
  
  METHODS
  The constituents were isolated by various chromatographic techniques (HP-20 macroporous absorption resin, Sephadex LH-20 gel, RP-MPLC and PHPLC)and their structures were determined on the basis of physicochemical properties and their spectroscopic data,as well as literatures.
  
  
  RESULTS
  Eleven compounds were separated and identified as p-methoxycinnamic acid(I), protocatechuic aldehyde(II), quercetin(III), isorhamnetin(IV), quercetin 3-O-beta-D-galactopyranoside (V),9-0-[beta-D-glucopyranoside]-3,4,5-trimethoxy cinnamyl alcohol(VI), syringaresinol-4'-O-beta-D-monoglucoside(VII), ntin(VIII), sibiraic acid(IX), sibiscolacton(X), methyl ferulic acid(XI).
  
  
  CONCLUSIONS
  Compounds I-XIII are isolated from the genus of Sibiraea for the first time.
