目的：以云南10个不同产地臭灵丹草为研究对象,测定其氨基酸组成及含量,对其营养价值进行评价,为臭灵丹草的资源利用及质量控制提供理论依据。方法采用氨基酸自动分析仪对氨基酸测定,利用氨基酸比值系数法和聚类分析法探讨不同产地臭灵丹草在氨基酸营养价值上的差异。结果各产地臭灵丹草中均含有17种氨基酸以及1种非蛋白类氨基酸γ-氨基丁酸,其中包括7种人体必需氨基酸,各产地臭灵丹草氨基酸总量为9.25%~19.74%,必需氨基酸含量为3.97%~8.63%,各产地臭灵丹草中氨基酸总量和必需氨基酸含量有明显差异,但各种氨基酸含量分布类似。臭灵丹草中氨基酸含量较高,且比例均衡,超过FAO/WHO提出的推荐值。臭灵丹草的氨基酸比值系数分(SRC)平均值为78.22,第一限制氨基酸为蛋氨酸+胱氨酸。臭灵丹草中含有丰富的药效氨基酸,占氨基酸总量的62.74%~66.48%。以氨基酸总量、必需氨基酸含量、药效氨基酸含量、必需氨基酸与氨基酸总量比值(E/T)、必需氨基酸与非必需氨基酸比值(E/N)、SRC 值等为指标,聚类分析将各地臭灵丹草分为4类。结论臭灵丹草具有较高的营养价值和保健作用,有待成为新资源食品,可进一步开发利用。

Objective To detect and evaluate the nutrition quality ofLaggera pterodonta(DC.) Benth from 10 regions of Yunnan through amino acids composition and content for providing a theoretical basis of the utilization and quality control ofLaggera pterodonta(DC.) Benth.MethodsAmino acid composition was analyzed with automatic amino acid analyzer. Ratio coefficient of amino acid method and cluster analysis were conducted to evaluate nutrition quality and distinguish differences among the heterotrophic strains ofL. pterodonta (DC.) Benth..ResultsAll samples had 17 kinds of amino acids andγ-aminobutyric, including 7 kinds of essential amino acids. The total amino acids content inL. pterodonta (DC.) Benth. from different regions was in range from 9.25%~19.74%, the essential amino acids content was in range from 3.97% to 8.63%.Although there were significant differences between total amino acids and essential amino acids from different region, theL. Pterodonta(DC.) Benth contained almost all essential amino acids in a well-balanced proportion, and the essential amino acid composition exceeded the FAO/WHO recommended pattern. With amino acids ratio coefficient,the score of amino acids ratio coefficient SRC was 78.22, the first limiting amino acids were Met+Cys, the medicinal amino acids took up 62.74%~66.48% of the total amino acids. In addition, the multivariate statistical method was used to analyze the differences in amino acid content, essential amino acid content, medicinal amino acid content, the ratio of essential amino acids and total amino acids (E/T), the ratio of essential amino acids and non essential amino acids (E/N)and SRC among the samples from 10 regions. These geographic origins were classified into 4 categories by cluster analysis. ConclusionL. pterodonta(DC.) Benth. has a high nutritional value and health benefit, and can be processed into natural green products.
