title: [Determination of 5F in Pteris semipinnata L. from various origins by TLC-scanning].
abstract: OBJECTIVE
  To determine the content of 5F in Pteris semipinnata L. from various origins.
  
  
  METHODS
  5F was determined by TLC-Scanning.
  
  
  RESULTS
  The linear relationship was in range of 0. 504 - 2. 520 microg. The mean recovery was 96. 68% and RSD = 1.24% (n = 5).
  
  
  CONCLUSIONS
  The method is available with a good reproducibility, and pretreatment is simple and easy to operate.
