title: [Isolation and identification of three steroid compounds from Mauremys mutics plastron].
abstract: OBJECTIVE
  To investigate the steroids components from extract of Mauremys mutics.
  
  
  METHODS
  The steroid compounds were isolated by using vacuum liquid chromatography and PTLC. The structures of three compounds were determined by spectral, chromatographic and chemical analysis.
  
  
  RESULTS
  Three steroids were isolated from M. mutics and identified as cholesterol, elcosenoic acid cholesterol ester, cholester-4-ene-3-one.
  
  
  CONCLUSIONS
  All the three compounds were isolated from M. mutics for the first time.
