摘　　要：对勐海及沧源2地龙竹笋基本营养成分、矿物质及氨基酸含量进行测定,与牡竹属常见竹笋及食用蔬菜的品质及营养价值进行对比分析。结果表明:龙竹笋含有丰富的蛋白质、总糖及适量的粗脂肪、粗纤维和单宁;其微量元素含量比较丰富,P、Mg、Ca元素含量尤其较高;氨基酸种类较齐全,人体必需氨基酸所占比例与其他牡竹属竹种相当,并高于常见食用蔬菜。其中勐海种源具有较高的含水量、总糖、蛋白质含量以及较低的粗纤维和单宁含量,较沧源龙竹笋口感更好;勐海龙竹笋Zn、Mn、Fe、Mg元素含量高于沧源龙竹笋;沧源龙竹笋P、K和Ca元素含量高于勐海龙竹笋;勐海龙竹笋氨基酸种类较沧源龙竹笋齐全,但沧源龙竹笋总氨基酸含量及人体必需氨基酸总含量明显比勐海龙竹笋丰富。We determined the basic nutrient components, mineral substance and amino acids of Dendrocalamus giganteus shoots harvested from Menghai and Cangyuan Counties and conducted a comparative analysis with the quality and nutrient value of Dendrocalamus bamboo species and common edible vegetables. The resuks showed that D. giganteus shoots contained rich protein, total sugar and moderate crude fat, crude fiber and tannins. It was also rich in trace elements, especially the P, Mg and Ca elements were particularly high. The amino acid types were complete, and the proportions of amino acids essential for human body were comparable with those in other Dendro- calamus bamboo species, whereas significantly higher than those in common vegetables. D. giganteus shoots from Menghai contained higher water content, total sugar, protein content but low crude fiber and tannin, tasting better than that from Cangyuan. D. giganteus shoots from Menghai contained higher Zn, Mn, Fe, and Mg than those from Cangyuan. D. giganteus shoots from Cangyuan contained higher P, K and Ca than those from Menghai. D. giganteus shoots from Menghai had complete amino acid types, but the total amino acid and essential amino acid was not ric- her than those of D. giganteus shoots from Menghai.
