title: [Study on fingerprints correlated with pharmacodynamic of constituents in Herba Erigerontis against neurotoxicity induced by beta-amyloid peptide].
abstract: OBJECTIVE
  To investigate the neuroprotective effects of the constituents in Herba Erigerontis on neuroblastoma SH-SY5Y cells, and find out its possible material foundation in treating Alzheimer's disease (AD).
  
  
  METHODS
  Different combinations of the three constituents in Herba Erigerontis were prepared according to the orthogonality experiment, and the indexes (MTT reduction assay, lipid peroxidation and expressions of nAChR alpha7 protein)were observed upon the SH-SY5Y cells followed by treatment of these combinations and beta-amyloid peptide (AP). The pharmacology data thus obtained and peak data in UPLC fingerprint were analyzed through ANOVA and correlationship by SPSS to give the information of active possible material foundation.
  
  
  RESULTS
  Constituents B and C showed clear activity and peaks of 4, 7-12 did positive correlationship according to the correlation of fingerprints and pharmacology.
  
  
  CONCLUSIONS
  This study makes a valid approach for deducing the active constituents even the exact compounds against neurotoxicity induced by Abeta by correlation of fingerprints and pharmacology.
