Abstract: To study the difference of amino acid content of different mushroom varieties, 14 mushroom varieties from market were selected as research object, 17 kinds of amino acid content of tested mushroom were used evaluation index, the tested 14 mushroom varieties were evaluated by subordinate function methods based on principle component analysis and classified by clustering methodology. The results showed that four principal components were extracted by principal component analysis of 17 index. cumulative contribution rate of four index reach to 86.909% and reflect better the comprehensive information of 14 tested mushroom varieties. Met, Lys, Val, Pro, His, Thr, Lys, Ile and Cys can be comprehensive evaluation index of 14 tested mushroom varieties by comprehensive analysis. the order of quality of 14 tested mushroom varieties by subordinate function methods were Copyinds comatus (MUII. Fr) Gray>Agaricus bisporus>Pleurotus eryngii>chashugu>Volvariella volvacea (Bull.:Fr.) Sing.>Lentinus edodes (Berk.)sing>Hypsizygus marmoreus (Peck) H.E.Bigelow>Stropharia rugoso-annulata Farlow apud Murrill>Flammulina velutipes>Pleurotus citrinopileatus>Russula pseudodelica Lang>Pleurotus tuber-regium (Fr.) Sing=Oudemansiella radicata>Pleurotus ostreatus.Clustering analysis showed that 14 mushroom varieties were clustered three groups, Group I with higher comprehensive grade includes Copyinds comatus (MUII. Fr) Gray, Agaricus bisporus, Pleurotus eryngii, and chashugu, Group II with middle comprehensive grade includes Volvariella volvacea (Bull.:Fr.) Sing., Lentinus edodes (Berk.)sing, Hypsizygus marmoreus (Peck) H.E.Bigelow, Stropharia rugoso-annulata Farlow apud Murrill, Flammulina velutipes, Pleurotus citrinopileatus, Russula pseudodelica Lang, Pleurotus tuber-regium (Fr.) Sing, Oudemansiella radicata, Group III with lower comprehensive grade includes Pleurotus ostreatus.
