不同品种桑葚与桑叶中氨基酸含量差异研究
目的 比较不同品种果桑中游离氨基酸总量、必需氨基酸及药用氨基酸含量差异。方法 以6个品种果桑(中葚1号、红果3号、831A、四季果桑、大白葚、江米果桑)的桑葚果实和桑叶为检测样品, 利用全自动氨基酸分析仪分别测定成熟期桑葚和桑叶中游离氨基酸含量。结果 6个供试品种桑葚和桑叶均含有19种游离氨基酸, 桑叶中氨基酸含量明显高于桑葚中氨基酸含量, 紫色果实品种的叶片中氨基酸总量高于白色果实品种, 紫色果实品种果实中的氨基酸总量又都低于白色果实品种, 两者呈相反趋势。结论 不同品种桑葚与桑叶中氨基酸存在较大差异。
Objective To compare the content of free amino acids, essential amino acids and medicinal amino acids in different varieties of mulberry. Methods With the 6 varieties of mulberry fruit and mulberry leaves (Zhongshen 1, Hongguo 3, 831 A, SiJi, Dabaishen, JiangMi) as samples, the free amino acid content in mulberry and mulberry leaves in mature period were measured by automatic amino acid analyzer. Results All the 6 varieties of mulberry and mulberry leaf contained 19 free amino acids, and the content of amino acids in mulberry leaves was significantly higher than that in mulberry leaves. The total amino acid content in leaves of purple fruit varieties was higher than that of white fruit varieties, the amino acid content of purple fruit varieties was lower than that of white fruit varieties, and the two trends were reversed. Conclusion There are great differences in amino acids between mulberry and mulberry leaves.
