Four kinds of traditional wild vegetables have been cultivated and utilized in Nanjing.Taking the egg protein as standard protein and WHO/FAO reference model of essential amino acid(EAA) as an appraisal criterion and putting 6 kinds of vegetables as a series of contrast, the authors evaluated the protein nutritional values of these cultivated wild vegetables in Nanjing by using the method of fuzzy discrimination and the method of ratio coefficient of amino acid(AA) respectively.The results showed that the protein contents of these wild vegetables ranged from 2.3%～5.0%.These gross proteins were rich in all kinds of AA which accounted for 77.73%～89.36%.EAA took up 36.72%～42.04% of total AA.The first limiting AA was sulfur containing AA, Met and Cys.The protein quality of these cultivated wild vegetables was far superior to that of some common vegetables belonging to the same family respectively.
