Abstract：In order to explore the difference of routine nutritional composition and amino acid content of three kinds of Phallus,the amino acid content of three kinds of P.rubrovolvata,P.indusiata and P.echinovolvata were determined by amino acid ratio coefficient method combined with amino acid score in FAO/WHO.The results showed that the three kinds of Phallus contained protein,fat,starch,ash,vitamin B6,B2 and other conventional nutrients.It accords with the characteristics of high protein and low fat of edible fungi.Seven kinds of mineral elements were detected in all three kinds of Phallus,including 5 kinds of essential trace elements for human body,and the contents of Ca and Fe were the highest.16 kinds of amino acids were detected by amino acid composition determination of more than 65 mg·kg-1;15 spe-cies of P.rubrovolvata and P.indusiata were detected,and 14 species of P.echinovolvata were detected,all of which were methionine.According to the comparison of the contents of essential amino acids in protein and egg protein recommend-ed by FAO/WHO,the proportion of essential amino acids in total amino acids was 35.14％,26.04％and 24.18％,respec-tively,in P.indusiata,P.rubrovolvata and P.echinovolvata.The amino acid content of P.echinovolvata was the most close to the requirement of ideal amino acid model of FAO/WHO model.AAS and CS showed that P.echinovolvata was higher than that of P.indusiata and P.rubrovolvata.The SRCAA of P.echinovolvata was 54.86,which was higher than that of P.indusiata(39.76)and P.rubrovolvata(14.90).The results showed that there were some differences in nutritional characteristics among different Phallus varieties,which also provided a theoretical basis for variety breeding and produc-tion promotion.
