title: [Analysis of lipid compounds of high-yielded rhizoma pinelliae growing in the west of Hubei province by gas chromatography-mass spectrometry].
abstract: OBJECTIVE
  To investigate lipid components of high-yielded Pinellia ternata rhizomes growing in the west of Hubei province.
  
  
  METHODS
  To determine the lipid chemical components in Pinellia ternata rhizomes with GC-MS method and NIST atlas.
  
  
  RESULTS
  Ten components have been found: palmitic acid (I), 9,12-octadecadienoic acid (II), pyrrolidine,1-(1-oxo-7,10-hexadecadienyl) (III), alpha-monpalmitin (IV), 1,3,12-nonadecatriene (V), campesterol (VI), stigmasta-5,22-dien-3-ol (VII), beta-sitosterol (VIII), stigmasta-5,24-dien-3-ol (IX), cycloartenol (X).
  
  
  CONCLUSIONS
  The relative contents of five kinds of phytosterol: campesterol 28.96%, stigmasta-5,22-dien-3-ol 9.24%, beta-sitosterol 50.77%, stigmasta-5,24-dien-3-ol 4.74%, cycloartenol 6.25%. Component II, III, V, VI, IX are the first time reported in Pinellia ternata.
