title: [Analysis on the volatile oil of Xinhui Pericarpium Citri Reticulatae in different years by GC/MS].
abstract: OBJECTIVE
  To analyze the difference of the volatile oil of Xinhui Pericarpium Citri Reticulatae in different years.
  
  
  METHODS
  The components and contents of the volatile oil of Xinhui Pericarpium Citri Reticulatae were analyzed in different years by GC/MS.
  
  
  RESULTS
  The components and contents of the volatile oil of Xinhui Pericarpium Citri Reticulatae changed along with the years.
  
  
  CONCLUSIONS
  With the years' extension, the components of the volatile oil changed slowly during 3 years but quickly after 3 years, a few new components appeared evenly, So there's relevance between using old Xinhui Pericarpium Citri Reticulatae and its component changing.
