To evaluate the quality of Rhizome of D. persimilis Prain et Burk.
Determined the contents of 6 qualitative indexes in samples of Rhizome of D. persimilis Prain et Burk that were cultivated in Yongning, Bobai, Beiliu, Guiping and Rongxian of Guangxi and in sample of Rhizome of Dioscorea opposita Thunb, that was cultivated in Wenxian, Henan province.
The contents of water in them (%): 15.39, 18.52, 15.41, 13.96, 15.48, 15.74; the contents of protein in them (%): 7.06, 8.45, 9.20, 9.67, 8.63, 9.79; the contents of starch in them (%): 84.51, 86.51, 82.72, 83.65, 84.19, 79.13; the contents of water extracts in them (%): 6.19, 6.98, 8.95, 7.41, 6.70, 9.40; 90% EtOH extracts in them (%): 2.00, 2.04, 2.68, 2.20, 2.11, 3.53; the contents of 18 kinds of amino acids in them (%): 5.23, 6.31, 6.22, 6.78, 6.59, 6.83.
The quality of Rhizome of D. persimilis Prain et Burk cultivated in Guiping or Beiliu is beter than that of Rhizome of D. persimilis Prain et Burk cultivated in Yongning. The quality of Rhizome of D. persimilis Prain et Burk cultivated in Rongxian or Bobai are between those of Rhizome of D. persimilis Prain et Burk cultivated in Guiping or Beiliu and Rhizome of D. persimilis Prain et Burk cultivated in Yonging. The qualities of Rhizome of D. persimilis Prain et Burk cultivated in Guiping or Beiliu are similar to that of Yam.
评价毛山药的质量。
测定广西玉林、博白、北流、桂平、容县栽培的毛山药样品及河南温县栽培的山药样品中6个定性指标的含量。
它们的水分含量（%）分别为：15.39、18.52、15.41、13.96、15.48、15.74；蛋白质含量（%）分别为：7.06、8.45、9.20、9.67、8.63、9.79；淀粉含量（%）分别为：84.51、86.51、82.72、83.65、84.19、79.13；水浸出物含量（%）分别为：6.19、6.98、8.95、7.41、6.70、9.40；90%乙醇浸出物含量（%）分别为：2.00、2.04、2.68、2.20、2.11、3.53；18种氨基酸含量（%）分别为：5.23、6.31、6.22、6.78、6.59、6.83。
桂平或北流栽培的毛山药质量优于玉林栽培的毛山药。容县或博白栽培的毛山药质量介于桂平或北流栽培的毛山药与玉林栽培的毛山药之间。桂平或北流栽培的毛山药质量与山药相似。
