title: [Analysis odor of Rhizoma Aatractylodis Macrocephalae based on electronic nose].
abstract: OBJECTIVE
  To appraise rationally the quality between wild and cultivated Rhizoma Atractylodis Macrocephalae.
  
  
  METHODS
  Evaporability composition of Rhizoma Atractylodis Macrocephalae was sampled from headspace of emanating, and then response values was obtained. Principal component analysis (PCA) and discriminant factor analysis (DFA) are used to combine the optimum feature parameters, and statistical quality control analysis (SQC).
  
  
  RESULTS
  The odor of wild Atractylodis Macrocephalae Rhizoma was diffenrent from that of the cultivated. The odor of Atractylodis Macrocephalae Rhizoma cultivated in Zhejiang was similar to the cultivated in Anhui which transplanted from Zhejiang and wild Atractylodis Macrocephalae Rhizoma which cultivated in the environment with full of sunlight. The odor of Atractylodis Macrocephalae Rhizoma cultivated in Hubei and Jiangxi were diffenrent to the odor of others.
  
  
  CONCLUSIONS
  The quality of semiwild cultivated Atractylodis Macrocephalae Rhizoma was the similarest to the wild. The electronic nose combined with PCA, DFA and SQC can be applied to identify the quality of Traditional Chinese Medicine.
