title: [Comparison of tanshinone IIA in Radix Salviae Miltorrhizae from Shandong].
abstract: OBJECTIVE
  To compare the contents of tanshinone IIA in Radix Salviae Miltorrhizae from different species, production places and collecting time, for study its quantity from Shandong.
  
  
  METHODS
  HPLC method was used.
  
  
  RESULTS
  The contents of tanshinone IIA in Radix Salviae Miltorrhizae of Shandong ranged from 0.330%-0.726%.
  
  
  CONCLUSIONS
  Setting the contents of tanshinone IIA as index, the quantity of Salvia miltiorrhiza Bge. f. alba C. Y. Wu et H. W. L. is better than Salvia miltiorrhiza Bge.. The genuine production place-Mengyin is the best planting area; the plantable place is mountaing district hillyland. Planting in plain region is inadvisable; the best collecting time is middle September.
