title: [Identification of the structure of two new nitro group phenolic glycosides from Schisandra propinqua (Wall. ) Baill var. intermidia A. C. Smith].
abstract: OBJECTIVE
  To study the bioactive components from Schisandra propinqua (Wall.) Baill var. intermidia A. C. Smith.
  
  
  METHODS
  Compounds were separated with a combination of multichromatography. Their chemical structures were determined on the basis of spectral analysis and chemical evidence.
  
  
  RESULTS
  Seven compounds were isolated from the leaves of Helicia nilagirica. The structures were elucidated as 6'-O-alpha-L-arabinofuranosylthalictoside (1), 6'-O-beta-D-apiofuranosylthalictoside (2), thalictoside (3), icariside D2 (4), prinsepiol (5), (+)-1-hydroxypinoresinol (6) and (+)-medioresinol (7).
  
  
  CONCLUSIONS
  Two compounds are new nitro phenolic glycosides.
