Analysis of Nutritional Components in Different Parts of Polygala fallax Hemsl.
To clarify the nutritional value of different parts of Polygala fallax Hemsl.,the water,ash,protein,total sugar,polysaccharide,fatty acids,amino acids and mineral elements in the root and stem of Polygala fallax Hemsl.were analyzed and evaluated.The results showed that the root and stem were high in various nutrients.Except for protein,the contents of water,ash,total sugar and polysaccharide in the root were slightly higher than those in the stem.In terms of fatty acids,24 and 25 fatty acids were detected in the root and stem,and saturated fatty acids accounted for 86.83％and 90.79％,respectively.At the same time,the types of amino acids in the root and stem were complete,mainly containing aspartic acid,tyrosine,glutamic acid and cystine,and the evaluation scores of essential amino acids were close to the FAO/WHO evaluation model.In addition,the root and stem were full of mineral elements,and the main elements were high potassium and low sodium.The root and stem were also rich in trace elements such as iron,manganese and zinc,and the ratio of zinc to copper and zinc to iron were reasonable.The research results provided scientific basis for the comprehensive development and utilization of Polygala fallax Hemsl.in the food industry.
