title: [Variation in yield and quality of Alisma orientalis grown under different ecological climatic regions].
abstract: To compare yield, alisol content of Alisma orientalis planted at different ecological climatic regions, and explore further the impact of environmental factors on the yield and quality.
  
  
  METHODS
  Different local varieties were planted at varing ecological climatic conditions. Diameter, yield was measured after harvest, the contents of 23-acetyl alisol B and 24-acetyl alisol A were quantitatively analyzed by HPLC.
  
  
  RESULTS
  The result revealed that ecological condition had significant impacts on yield and alisol content. Yield of MeiShan was the highest which was up to 1 200.72 kg x hm(-2). The contents of 23-acetyl alisol B and 24-acetyl alisol A of A. orientalis cultivated in Dujiangyan were significantly higher than those of other regions, the values were up to 4.222, 2.727 g x kg(-1), respectively. 23-acetyl alisol B content was positively correlated with 24-acetyl alisol A content (P < 0.01). The diameter was positively correlated with yield (P < 0.01).
  
  
  CONCLUSIONS
  Considering yield and medicinal ingredients, Dujiangyan may be the most suitable region to plant A. orientalis.
