title: [Studies on furmaric acid and isofraxidin content in Sarcandra glabra of different provenances].
abstract: OBJECTIVE
  To study the content variation of furmarid acid and isofraxidin in Sarcandra glabra from 21 different provenances and provide the basis for resource utilization and quality optimization of S. glabra.
  
  
  METHODS
  HPLC method was developed to determine the contents of furmarid acid and isofraxidin in 330 samples of S. glabra which were collected respectively from 21 different provenances.
  
  
  RESULTS
  There were significant differences in the contents of isofraxidin and furmarid acid in S. glabra from different provenances. The contents of isofraxidin and furmarid acid dropped off from low altitude to high altitude, which were also close with longitude and latitude. The content of isofraxidin in S. glabra at central area of natural distribution was the highest. The different parts of the plant had different results, the influence on the contents of the acitive components in stem were more obvious than the leaf.
  
  
  CONCLUSIONS
  This simple, accurate and reproducible method could be use to determine the contents of furmarid acid and isofraxidin in S. glabra. The results represented the status of medicines quality and difference of Chinese S. glabra. These agreed with the traditional views that the medicines quality of Sarcandra glabra in Jiangxi, Fujian, Zhejiang was better. These provenances were considered as important areas of medicines breeding and bases building on S. glabra in future.
