title: [Determination of lignans in four fruits of Schisandra genus in Qinling mountains].
abstract: OBJECTIVE
  To determine the content of four lignans in the fruits of Schisandra sphenanthera, Schisandra grandiflora, Schisandra rubriflora and Schisandra propinqua subsp. sinensis.
  
  
  METHODS
  The HPLC separation was performed on Diamonsil C18 (150 mm x 4.6 mm, 5 microm) columm using methanol-water (70 : 30) as the mobile phase at a flow rate of 0.8 mL/min, with the detection wavelength of 280 nm.
  
  
  RESULTS
  Schisandrin, deoxyschizandrin and gamma-schizandrin were detected in four species of Schisandra. The content of schisantherin A in S. sphenanthera was measured up to the set standards of the Chinese Pharmacopoeia (2010 Edition). The content of deoxyschizandrin was high in S. grandiflora and S. rubriflora, and that of gamma-schizandrin was high in S. propinqua subsp. sinensis.
  
  
  CONCLUSIONS
  The content of lignans is different in four species of Schisandra fruits in Qinling Mountains, it provides scientific reference for further study.
