title: Chemical composition of the essential oil and fixed oil Bauhinia pentandra (Bong.) D. Dietr.
abstract: BACKGROUND
  Bauhinia pentandrais popularly known as "mororó" and inhabits the Caatinga and Savannah biomes.
  
  
  OBJECTIVE
  This paper reports the chemical composition of the essential and fatty oils of the leaves from B. pentandra.
  
  
  METHODS
  The essential oil was obtained by hydrodistillation and the fixed oil by extraction with hexane, followed by saponification with KOH/MeOH, and methylation using MeOH/HCl. The constituents were analyzed by gas chromatography-mass spectrometry.
  
  
  RESULTS
  The major constituent of the essential oil was the phytol (58.78% ±8.51%), and of the fatty oil were palmitic (29.03%), stearic (28.58%) and linolenic (10.53%) acids.
  
  
  CONCLUSIONS
  Of the compounds identified in the essential oil, three are first reported in this species, and this is the first record of the chemical composition of the fixed oil.
