title: [Studies on dynamic variation of six isoflavones contents in rhizomes of Belamcanda chinensis].
abstract: OBJECTIVE
  To study the monthly dynamic variation of the contents of six isoflavones in the rhizomes of Belamcanda chinensis cultivated in Nanjing, and decide optimum harvesting times.
  
  
  METHODS
  HPLC method was used to determine the contents of six isoflavones in the samples collected at different times.
  
  
  RESULTS
  It was shown that the total contents of six isoflavones in the rhizomes of B. chinensis collected in April were the highest.
  
  
  CONCLUSIONS
  The most optimum collecting time of rhizomes of B. chinensis cultivated in Nanjing should be in April.
