title: [Studies on the chemical constituents of the volatile oil from Radix Cudramiae].
abstract: OBJECTIVE
  To study the chemical constituents of the volatile oil from Radix Cudramiae.
  
  
  METHODS
  The oil was obtained by steam distillation. The chemical compositions were separated and identified by GC-MS. The relative contents in the oil were determined by area nomalization.
  
  
  RESULTS
  Sixty-four compounds were obtained from Radix Cudramiae. The relative contents of twenty-three compounds were more than 1%. The highest relative content was L-linalool (9.852%).
  
  
  CONCLUSIONS
  Sixty-four compounds characterized by GC-MS analysis were obtained from Radix Cudramiae for the first time.
