Abstract: Abstract: The research explored the relationship between nutritional components of Chenopodium quinoa willd seeds and elevation of cultivation areas in order to provide scientific references for standard cultivation and supplying of Chenopodium quinoa willd in the northwest of Yunnan province. A field experiment was performed in four sites with varying elevations and effects of elevation on seeds of Chenopodium quinoa in terms of protein, ash content, amino acid, and trace elements were reviewed. The results showed that in Chenopodium quinoa seeds, sugar, ash content, manganese, potassium, aspartic acid, glutamic acid, valine, isoleucine, tyrosine, arginine, and amino acid contents were all going up as the elevation increased, but crude fiber, palmitic acid, α-linolenic acid, and copper contents were going down. Nutritional components of Chenopodium quinoa seeds have been closely linked to elevation of the cultivation area, and it is necessary to arrange planting work scientifically, with consideration of practical demands.
