| 摘 要： | 以新疆尉犁县野生黑果枸杞与黑杞一号为试材,测定其总糖、还原糖、脂肪、蛋白质含量及氨基酸组分,探讨其营养价值。结果表明,野生黑果枸杞与黑杞一号的各基本营养成分差异显著,野生黑果枸杞的总糖和还原糖含量相对较高,总酸、脂肪和蛋白质含量相对较低。两种黑果枸杞中氨基酸种类较齐全,至少有17种。其中,人体必需氨基酸7种、儿童必需氨基酸2种、甜味氨基酸6种、苦味氨基酸7种、酸鲜味氨基酸2种、芳香族氨基酸6种、支链氨基酸3种、药效氨基酸7种。在氨基酸总量以及儿童必需氨基酸、酸鲜味氨基酸、药用氨基酸与总氨基酸比例方面,野生黑果枸杞的含量低于黑杞一号。在必需氨基酸、甜味氨基酸、苦味氨基酸、芳香族氨基酸、支链氨基酸与总氨基酸比例方面,野生黑果枸杞的含量高于黑杞一号。与FAO/WHO氨基酸模式谱比较,两种黑果枸杞的Met+Cys、Ile、Val和Leu基本符合氨基酸模式谱要求,Thr和Phe+Tyr相对过剩,Lys相对较低。氨基酸比值系数（RC）分析表明,野生黑果枸杞的蛋白质品质优于黑杞一号。

| Abstract: | Taking the wild and Heiqi No.1 Lycium ruthenicum Murr. of Xinjiang Yuli County as test materials, analyzing their total sugar, reducing sugar, fat and protein content and the component of amino acid, in order to explore their nutritional value.The results showed that there was a significant difference between the wild and Heiqi No.1's nutrient content.Comparing with Heiqi No.1, the wild's total sugar and reducing sugar content were higher, the total acid, fat and protein content were lower.The Lycium ruthenicum Murr.contained all kinds of essential amino acids, at least 17 kinds, including 7 essential amino acids, 2 children essential amino acids, 6 sweet amino acids, 7 bitter amino acid, 2 sour taste amino acids, 6 aromatic amino acids, 3 branched chain amino acids and 7 medicinal amino acids.The wild's content of total amino acid and the proportion of children essential amino acids, sour taste amino acids, medicinal amino acids in the total were lower than Heiqi No.1's.But its proportion of essential amino acids, sweet amino acids, bitter amino acids, aromatic amino acids and branched chain amino acids of the total were higher than Heiqi No.1's.Comparing with the FAO/WHO amino acid pattern spectrum, Lycium ruthenicum Murr.'s Met + Cys, Ile, Val and Leu conformed to the requirements, Thr and Phe + Tyr were higher, Lys was lower. The analysis of RC showed that, the wild's protein quality was better than Heiqi No.1's. |
