title: [GC-MS analysis of volatile oil components from Aquilariae Lignum Resinatum concreted by a new artificial method].
abstract: OBJECTIVE
  To study the chemical constituents of the volatile oil from Aquilariae Lignum Resinatum by the technical of Aquilariae Lignum Resinatum making incense.
  
  
  METHODS
  Volatile Oil Extraction method was used to extract volatile constituents from different batches of Aquilariae Lignum Resinatum, and the composition was analyzed by GC-MS.
  
  
  RESULTS
  56 chemical constituents were extracted from Aquilariae Lignum Resinatum, 36 constituents of them were reported for the first time;The chemical constituents were slightly different among three batches of Aquilariae Lignum Resinatum, but all the volatile oils were mainly composed of sesquiterpenes and aromatic composition; And all three batches of samples contained characteristic active ingredients including Aloes spiral alcohol, Benzyl acetone and the contents of them had increasing trend with the Aquilariae Lignum Resinatum concreting period growing.
  
  
  CONCLUSIONS
  Chemical constituents extracted from the Aquilariae Lignum Resinatum concreting by new method were similar with natural Aquilariae Lignum Resinatum, and in a relatively short period of time, can produce relatively high content of effective and characteristic components.
