Unlabelled:
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.
Method:
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.
Result:
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).
Conclusion:
Considering yield and medicinal ingredients, Dujiangyan may be the most suitable region to plant A. orientalis.
