title: [The quality of Salvia miltforthiza from Beijing suburbs with different growing modes].
abstract: OBJECTIVE
  Study the yield and quality of Salvia miltforthiza in the poplars and apple trees intercropping system.
  
  
  METHODS
  Assay the yield, heavy metals, organochlorine pesticides and active components of Salvia miltforthiza in different intercropping systems are different.
  
  
  RESULTS
  The contents of Cd exceeds the allowed figure seriously though other heavy metals such as Pb, As, Hg, Cu fell in the standard range. The contents of organochlorine pesticides of different Salvia miltforthiza fell in the standard range. The active components of biennial Salvia miltforthiza intercropping with apple trees, including Tanshinone II A and Salvianolic acid B complied with the quality standards of Pharmacopoeia.
  
  
  CONCLUSIONS
  Soil fertility, heavy metals of intercropping system and planting years should be considered in order to ensure the quality and stability of Chinese medicine.
