•Nutrient composition of R. amabilis from Qinghai-Tibetan Plateau studied for 1st time.•Amino acid, fatty acid, mineral contents of Rubus amabilis were analyzed.•Results showed that leaves contain higher TAA than other plant parts.•High amounts of methionine are present in free and total amino acids.•The leaf contains 36.5% unsaturated fatty acids and linolenic acid.
The amino acid, fatty acid, and mineral content of Rubus amabilis harvested from the Qinghai-Tibetan Plateau were analyzed. Results revealed that the total amino acids in the leaves, fruits, roots, and stems of R. amabilis were 17.1, 7.5, 6.5, and 5.7 g, respectively. Further analysis of the amino acids showed that the protein contained nutritionally useful quantities of essential amino acids. The total essential amino acids in the leaves of R. amabilis were 9.3 g ETAAs/100 g. Total fatty acids varied in different parts of R. amabilis. Stearic acid, linolenic acid, linoleic acid, and palmitic acid in the leaf samples were 41.4%, 13.7%, 11.9%, and 6.7%, respectively. Lauric acid, oleic acid, docosahexoenoic acid, and eicosenoic acid were present only in small quantities. Potassium, magnesium, and calcium were the most abundant minerals in the leaf samples. Among the essential trace mineral elements, Fe exhibited the highest content in different parts of R. amabilis.
