Amino Acid and Fatty Acid Compositions and Evaluation of Wild Rosa davurica
[Objective]To explore the difference of amino acid and fatty acid content in wild Rosa davurica seeds,so as to provide scientific basis for the development,utilization and cultivation direction of wild Rosa davurica.[Method]Amino acid and fatty acid composition,content and nutritional evaluation of seeds in wild Rosa davurica in Heilongjiang province and surrounding areas were analyzed.[Result]The total content of amino acid was 19.49%—24.48%,the average was 22.46%.The average content of essential amino acids was 7.26%,accounting for 27.13%—37.26%of the total amino acids.The average content of medicinal amino acids was 16.27%,essential amino acids for children was 3.77%,aromatic amino acids was 8.53%,branched amino acids was 3.77%,umami amino acids was 7.73%,sweet amino acids was 3.17%.SRC was 69.29-83.39,average was 74.125,the protein was close to the ideal protein requirement,and Met was the first limiting amino acid.The total content of fatty acid was 95.33%,unsaturated fatty acid was 90.24%.The fatty acid composition was shown as:linoleic acid>linolenic acid>oleinic acid>pentadecanoic acid>stearic acid>arachidonic acid>palmitoleic acid.There was a significant positive correlation between pentadecanoic acid and palmitoleic acid(r=0.606,P<0.01),stearic acid was positively correlated with arachidonic acid and linolenic acid(P<0.01),linolenic acid was negative correlated with linoleic acid(r=-0.470,P<0.01).Q-type clustering analysis with Euclidean distance 20 as the threshold,14 varieties could be clearly divided into four categories.[Conclusion]Combining the composition and content of amino acids,fatty acids and SRC,producing area in Muling was considered to be the best variety with health care and medicinal functions,while Berry Research Institute in Suiling was relatively suitable for children's health food.
