title: [A new benzophenone from the root of Securidaca inappendiculata].
abstract: OBJECTIVE
  To study the benzophenones in the roots of Securidaca inappendiculata Hassk.
  
  
  METHODS
  Column chromatography (including silica gel and Sephadex LH-20) was used to isolate benzophenones whose structures were elucidated by HREI-MS, NMR (1D and 2D) methods.
  
  
  RESULTS
  A new benzophenone was isolated and identified as 2-methoxy-3,4-methylenedioxy-benzophenone (I), along with a known compound 4-hydroxy-2,6-dimethoxy-benzophenone (II).
  
  
  CONCLUSIONS
  Compound I is a new one named as securiphenone B, compound II was isolated from the genus for the first time.
