title: [The extraction and effects on mouse lymphocyte proliferation of immunoregulation components from Lysimachia hemsleyana].
abstract: OBJECTIVE
  To study the effects of extracted fractions from the whole plants of Lysimachia hemsleyana Maxim on the proliferation ability of lymphocytes in mice in vitro.
  
  
  METHODS
  We extracted the components by using of ethanol, ether from petroleum, chloroform, ethyl acetate and n-butanol, successively then study them on the proliferation of lymphocytes in mice.
  
  
  RESULTS
  The n-butanol fraction obviously inhibited the proliferation of spleen lymphocytes induced by LPS, bilaterally regulated the T lymphocyte proliferation induced by ConA. The chloroform fraction markedly enhanced the lymphocytes proliferation induced by ConA or LPS.
  
  
  CONCLUSIONS
  The results suggested that n-butanol fraction and chloroform fraction from Lysimachia hemsleyana possibly maybe have immunoregulation effects.
