-
摘要: 目的 对构树地上不同部位的氨基酸成分进行分析.方法 采用日立835-50型氨基酸自动分析仪分析氨基酸组分.结果 构树各部分包括果实、叶或花序、聚合果至少含有16种以上的氨基酸,以天冬氨酸、谷氨酸、精氨酸、缬氨酸、脯氨酸、赖氨酸等为主,其中7种为人体必需氨基酸.以100g干燥样品粉末计,楮实子、构树叶、雄花序、聚合果总氨基酸含量分别为12.44g、24.5g、15.88g、11.94g,人体必需氨基酸总量分别为3.92g、9.95g、9.7g、3.27g.不同生长时期构树叶及果实的氨基酸含量存在显著差别.结论 构树叶及聚合果中含有丰富的氨基酸,具有进一步开发利用价值.Abstract: Objective To determine constituents of amino acids in the aerial parts of Broussonetia papyrifera.Methods The constituents composition of the ammo acid of the aerial parts of Broussonetia papyrifera were analysised by Hitachi 835-50 automatic amino acid analyzer (Hitachi 835-50) Results All the aerial parts of Broussonetia papyrifera contain at least 16 kinds of amino acid, the main amino acids are asparlate、glumatic acid、 arginine、valine、proline and lysine, and seven of them are essential amino acids for human body.The fruits, leaves, male inflorescences and the aggregate fruits of Broussonetia papyrifera contain 12.44、24.35、15.88、11.94 gram total Amino acids and 3.92、9.95、9.7、3.27gram essential amino acids in 100 gram of sample powder respectively.The content of amino acids of leaves and fruits of Broussonetia papyrifera varies with different growing stages.Conclusion The leaves and aggregate fruits of Broussonetia papyrifera contain rich amino acids, which reserved to be further exploited.
