摘要
目的:比较不同生态气候区泽泻产量和品质的差异,并分析差异的原因。方法:以川产泽泻4个地方种为材料,在四川7个生态气候区育苗移栽,成熟收获后,测定其直径、产量及药用成分含量。并进一步研究其直径与产量的相关性,及主要药用成分之间的相关性。结果:不同生态气候区泽泻产量存在显著差异,其中眉山的产量最高,达1 200.72 kg.hm-2,其次为都江堰的,达1 167.51 kg.hm-2,宜宾的产量最低,为417.54 kg.hm-2;都江堰的泽泻块茎中23-乙酰泽泻醇B和24-乙酰泽泻醇A含量均显著高于其他生态气候区,分别达4.222,2.727 g.kg-1。泽泻块茎的直径大小与其产量呈极显著正相关,23-乙酰泽泻醇B含量与24-乙酰泽泻醇A含量也呈极显著正相关。结论:综合产量与品质来看,都江堰的质量最佳,眉山的次之,邛崃的最差。
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 · 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 ·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.
