title: [Analysis of petroleum fraction from flower, stem and leaf of Aconitum taipeicum by GC-MS].
abstract: OBJECTIVE
  To analyze the chemical constituents of petroleum fraction of Aconitum taipeicum.
  
  
  METHODS
  The methanol extract of Aconitum taipeicum were extracted by petroleum and then analyzed by GC-MS. The compounds were quantitatively determined by normalization method.
  
  
  RESULTS
  Twenty eight compounds were separated and identified. Most of them were alkane, fat acids and their esters and alkenes. The Nonacosane covered 13.057% of the total peaks, while 19-methyl-18,21-Hexatriacontanediether 8.180%, Ethylen eglycol monooctadecy ether 7.851%, 3,7,11,15-Tetramethyl-2-hexadecen-1-ol 7.805%, Metahyl Palmitate 6.676% and so on.
  
  
  CONCLUSIONS
  This is the first report of constituents from the flower, stem and leaf of Aconitum taipeicum. The results will provide foundation for further exploitation and use of Aconitum taipeicum.
