OBJECTIVE
To determine the contents of gastrodin, amino acids and total flavonoids in wild and cultivated Gastrodia elata, in order to choose the best method for its cultivation. The Gastrodia elata was picked at Guxiang town Bomi county Linzhi Region in Tibet.
METHODS
HPLC was used to determine the content of gastrodin. The autoanalyzer was used to determine the content of amino acid. The ultraviolet spectrophotometer was adopted to measure the content of total flavonoids.
RESULTS
The Gastrodin in wild Gastrodia elata was the highest. The contents of amino acids and total flavonoids in organic cultivated Gastrodia elata were higher than those in common cultivated and wild Gastrodia elata.
CONCLUSION
The organic cultivated Gastrodia elata has better quality.
目的
测定野生和栽培天麻中天麻素、氨基酸及总黄酮的含量，以选择最佳栽培方法。天麻采自西藏林芝地区波密县古乡。
方法
采用高效液相色谱法测定天麻素含量。用自动分析仪测定氨基酸含量。采用紫外分光光度计测定总黄酮含量。
结果
野生天麻中天麻素含量最高。有机栽培天麻中氨基酸和总黄酮的含量高于普通栽培和野生天麻。
结论
有机栽培天麻质量更佳。
