title: [Studies on chemical constituents of root of Millettia speciosa].
abstract: OBJECTIVE
  To study the chemical constituents from the root of Millettia speciosa.
  
  
  METHODS
  To isolate and purify by silica gel, macroporous resin D-101 and Sephadex LH-20.
  
  
  RESULTS
  Five compounds were isolated from 95% EtOH extract of Millettia Speciosa and their structures were elucidated by physico-chemical properties and spectroscopic analysis as Isoliquiritigenin (I), Maackiain (II), Pterocarpin (III), Medicarpin (IV) and Homopterocarpin (V).
  
  
  CONCLUSIONS
  Compounds I, III are obtained from this plant for the first time, compounds V is isolated from the genus Millettia for the first time.
