title: [Comparison on appearance and non-ginsenoside composition in Panax ginseng and its products processed from different producing areas in northeast China].
abstract: OBJECTIVE
  To investigate the appearance and moisture, ash content, extract, volatile oil of Panax ginseng and its processed products from different producing areas of northeast China, and thus provide the useful reference data for its quality standard establishment and standardized cultivation.
  
  
  METHODS
  Base on the Chinese Pharmacopoeia and literatures relating to P. ginseng, the content of moisture, ash, extract, volatile oil in P. ginseng and its processed products from northeast 10 different producing areas were measured, and data analysis of these various indicators was carried out by DTOPSIS.
  
  
  RESULTS
  The samples from Changbai, Jian Kangmei and Fusong reached the standard of Chinese pharmacopoeia and national standard, and in addition comprehensive evaluation indicators of them were higher than others samples.
  
  
  CONCLUSIONS
  The quality of ginseng from different producing areas appears very different. Some samples failed to reach the standard of Chinese pharmacopoeia and national standard. Ginseng samples from those 3 producing areas of GAP planting bases showed good quality, which reflects the importance of GAP for ginseng cultivation.
