title: [Study on Chemical Composition of Phyllanthus emblica].
abstract: OBJECTIVE
  To study the chemical constituents of Phyllanthus emblica.
  
  
  METHODS
  The chemical constituents were isolated and purified by silica gel, polyamide and Sephadex LH-20 chromatography. Their structures were elucidated by physicochemical proper- ties and spectral analysis.
  
  
  RESULTS
  13 compounds were isolated and identified as Triacontanol (1), Triacontanoic acid (2), β-Amyrin ke- tone (3), Betulonic acid (4), Daucosterol (5), Lupeol acetate (6), β-Amyrin-3-palmitate (7), Gallic acid (8), Betulinic acid (9), Ursolic acid (10), Oleanolic acid (11), Quercetin (12) and Rutin (13).
  
  
  CONCLUSIONS
  Compounds 1,2,4,6,7,9,10 and 11 are obtained from Phyllanthus emblica for the first time.
