title: [Pharmacognostical study on Berchemia floribunda].
abstract: OBJECTIVE
  To study the pharmacognostical characteristics of stem and root of Berchemia floribunda for its further research and usage.
  
  
  METHODS
  The plant was researched by macroscopic identification, microscopic identification and thin layer chromatography.
  
  
  RESULTS
  The transverse section of B. floribunda root was eccentric. There were many fiber bundles in the secondary phloem and two different stone cells distributed in stem and root respectively. The results of TLC could identify the stem and root of B. floribunda.
  
  
  CONCLUSIONS
  The microscopic characteristics of B. floribunda stem and root can be used as reference for its identification. Quercetin can be used as the characteristic component to identify the stem and root.
