title: [Chemical constituents of Desmodium caudatum].
abstract: OBJECTIVE
  To study the chemical constituents of Desmodium caudatum.
  
  
  METHODS
  Silica column chromatography, Sephadex LH-20 column chromatography and recrystallization were used to separate and purify the chemical composition of Desmodium caudatum. Their chemical structures were identified by infrared spectrum (IR), mass spectrum (MS), nuclear magnetic resonance (NMR) and other physicochemical methods.
  
  
  RESULTS
  Twelve compounds were isolated and identified as lacceroic acid(1), gheddic acid(2), stigmasterol(3), betulin(4), citrusinol(5), yukovanol(6), kaempferol(7), protocatechuic acid(8), sophocarpine(9), matrine(10), N, Ndimethyltryptamine(11) and 5-hydroxy-N,N-dimethyltryptamine(12).
  
  
  CONCLUSIONS
  Compounds 1, 2, 4 and 8-12 are isolated from this plant for the first time.
