Objective:To clarify the quality of Gastrodia elata cultivated with different woods material.Method:G.elata Bl.f.glauca and G.elata Bl.f.elata cultivated from Cyclobalanopsis glaucoides and Alnus nepalensis were used as the research objects.The gastrodin content,five kinds of heavy metals content,mineral elements content and amino acid composition of four samples were determined.The amino acids content of G.elata were analyzed and evaluated through the amino acid ratio coefficient method,as well as the whole egg protein model and the FAO/WHO model.Results:There was no dif-ference in gastrodin content between the two cultivars,and the total amount of amino acids was 339.52-1 365.71 mg/100 g.The content of flavor amino acid and medicinal amino acids were rich,and the pro-portion of fresh sweet amino acids was large,which ranged from 73.73%to 83.09%.The highest con-tents of medicinal amino acids in G.elata Bl.f.glauca was cultivated with A.nepalensis(941.13 mg/100 g),and the second was G.elata Bl.f.elata cultivated with C.glaucoides(992.91 mg/100 g),and the levels of aspartic and glutamic acid were especially high.Conclusion:The results provided a good theoretical reference for the breeding and intensive processing of G.elata.
