摘　　要： 【目的】研究了滇重楼茎、叶、花和根茎的氨基酸组成、含量以及营养价值,为滇重楼资源的综合利用提供理论依据。【方法】滇重楼茎、叶、花和根茎的氨基酸测定采用日立L-8800氨基酸自动分析仪,营养评价采用氨基酸比值系数法。【结果】滇重楼茎、叶、花和根茎中均检测出17种常见氨基酸(色氨酸被水解破坏未检出),其氨基酸总量叶(13.96%)>花(10.92%)>茎(4.54%)>根茎(4.02%);滇重楼茎、叶、花和根茎中富含药效氨基酸,且均检出γ-氨基丁酸;滇重楼的茎、叶、花和根茎中均含有8种呈味氨基酸,其含量分别为2.86%、8.21%、6.18%、2.34%;滇重楼的茎、叶、花和根茎中必需氨基酸与总氨基酸的比值(E/T)分别为0.35、0.39、0.39、0.38,必需氨基酸与非必需氨基酸的比值(E/N)分别为0.53、0.65、0.65、0.61,氨基酸配比较为合理;滇重楼植株的必需氨基酸含量接近FAO/WHO推荐的标准模式谱,有较高的营养价值;滇重楼茎、叶、花和根茎中蛋氨酸+胱氨酸均为第一限制氨基酸,营养价值从高到低依次为根茎>叶>茎>花。【结论】滇重楼地上部分具有较高的营养价值和保健作用,可作为动物饲料对其进行开发利用。 [Objective]The amino acids composition, content and nutrition quality of Paris polyphylla Smith var. yunnanensis（ Franch. ） Hand. -Mazz. were studied for providing a theoretical basis of the utilization. [ Method] To analyze the composition and determination of hy- drolyzed amino acids in P. polyphylla Smith var. yunnanensis（ Franch. ）Hand.-Mazz, the L-8800 amino acid mobile analyzer was used. And amino acids ratio coefficient method was used to evaluate nutrition in P. polyphylla var. yunnansensis. [ Result]There were 17 kinds of hydrolyzed amino acids in stems, leaves, flowers and rhizomes of P. polyphylla var. yunnansensis. The total contents of hydrolyzed amino acids from rich to low was as following leayes（ 13.96 % ） 〉 flowers（ 10.92 % ） 〉 stems（ 4.54 % ） 〉 rhizomes（4.02 % ）. There were rich in pharmacodynamic amino acids of stems, leaves, flowers and rhizomes. The γ-Aminobutyric acid was identified in stems, leaves, flowers and rhizomes of P. polyphylla var. yunnansensis. The total contents of taste amino acids of stems, leaves, flowers and rhizomes in P. polyphylla vat. yunnansensis was 2.86 %, 8.21% ,6.18 % and 2.34 % respectively. The ratio of essential amino acids content and total amino acids content of stems, leaves, flowers and rhizomes in P. polyphylla var. yunnansensis was 0.35,0.39,0.39,0.38 respectively, while the ratio of the essential amino acids content and total amino acids content of them were 0. 53,0. 65,0. 65,0. 61. The essential amino acids were closed to the FAO/WHO standard. The protein of P. polyphylla var. yunnansensis had a high nutritional value. Met ＋ cys was the first limiting amino acid of stems, leaves, flowers and rhizomes. Amino acid distributions were appropriate. Amino acid distributions were appropriate, and the nutrition value from rich to low as following rhizomes 〉 leaves 〉 stems 〉 flowers. [ Conclusion ] The stems, leaves, flowers of Paris polyphylla Smith var. yu.nnanensis （Franch.） Hand. -Mazz had a high nutritional value and
