title: [Effects of environmental factors on volatile constituent ligustilide of slices of Chuanxiong Rhizoma].
abstract: OBJECTIVE
  To investigate the effects of environmental factors on the volatile constituent ligustilide of the slices of Chuanxiong Rhizoma.
  
  
  METHODS
  To study the optimal condition for storage of Chuanxiong Rhizoma slices by orthogonal design. The storage condition was optimized with illumination, oxygen, temperature and storage time as the observation factors. Each factor set three levels. With ligustilide as deteciion index,the content was measured by HPLC.
  
  
  RESULTS
  Temperature was the primary factor of the content of ligustilide,the second was the storage time, then the illumination. The influence of oxygen was the smallest.
  
  
  CONCLUSIONS
  The optimum condition for storage of the slices of Chuanxiong Rhizoma is sealed package,under weak light and low temperature,with storage time as short as possible.
