摘要 To evaluate the nutritional value of four kinds of wild vegetables,and to provide reference for guiding the Yi People in Liangshan to balance their diet and rational nutrition,the main nutritional ingredients included amino acid,fat,energy,vitamins and minerals in the four species of wild edible vegetables were detected and studied using the national standard methods.The four species of wild vegetables were Cardamine tangutorum,Aralia chinensis,Cirsium shansiense and Smilax stans,which were favorite food of the Yi People in Liangshan,Sichuan Province.The results were as follows:There are at least 17 kinds of amino acids in these four wild vegetables,of which seven were essential amino acids,and a variety were medicinal amino acids.Among the four wild vegetable,the content of glutamic acid in Cirsium shansiense was higher,accounting for 0.41%,and the contents of aspartic acid in Smilax stans,Cardamine tangutorum and Cirsium shansiense were higher,accounting for 0.80%,0.33%,and 0.05%,respectively.The amount of essential amino acid/total amino acid(EAA/TAA)and essential amino acid/non-essential amino acid(EAA/NEAA)of Cirsium shansiense were the highest,which were 34.44% and 67.78%,respectively.Compared with the cultivation of root vegetables and leafy vegetables on the Chinese Food Ingredients Tables,the protein content of Cardamine tangutorum was higher,accounting for 3.26%,and rich in vitamins(VA,VB,VB2,VC,VE and beta-carotene).The custom of Liangshan Yi People like the four wild vegetables is closely related to their nutritional needs,dietary habits and culture.The results indicate that the four wild vegetables have the characteristics with high energy,low sodium,low crude fiber content,good taste and rich in mineral elements(copper,iron,zinc,manganese and magnesium),and have high nutritional value and health benefits.This study provides theoretical basis for scientific development and utilization of wild vegetable resources in Liangshan,and provides reference for the development of agricultural diversity in mountain areas.
