title: [Quality estimation on material medica of Rhizoma Paridis from Sichuan & Yunnan province].
abstract: OBJECTIVE
  To provide valuable reference for comprehensive qualitative estimation and reasonable utilization of material medica Rhizoma Paridis.
  
  
  METHODS
  Rhizoma Paridis collected from different region of southwest Sichuan & northwest Yunnan. The texture and the content of parissaponin I, II, VI, VII were observed a nd measured b y HPLC.
  
  
  RESULTS
  The difference of target compounds' content among samples from different producing area is significant; the eligibility rate of material medica is only 25%; the texture of material medica has certain relativity with content of parissaponin.
