不同品系忍冬果实中氨基酸和微量元素比较

Comparison on amino acid and trace elements in different strains of Lonicera japonica Thunb. fruit

目的:为忍冬Lonicera japonica Thunb.果实的开发利用及优良品种选育提供基础数据。方法:利用色谱法测定氨基酸含量;利用原子吸收分光光度法测定微量元素含量。结果:品系YTH-001、品系YTH-002和品系YTH-003 3个品系中各氨基酸含量较为相似,品系JYH-001和品系SYH-001中各氨基酸含量均较少;不同品系忍冬果实Zn、Fe、Sn元素含量的差异与它们之间的亲缘关系有密切联系。YTH-001、YTH-002、YTH-003三个品系为良种"亚特红"及其变型,亲缘关系较近。结论:"亚特红"品系忍冬果实较其它品系忍冬果实富Zn、Fe,具有较高开发价值。

Objective: To provide basic data for the development, the utilization and the breeding of fine varieties of Lonicera japonica Thunb. fruit. Methods: The content of amino acids was determined by chromatography. The content of trace elements was determined by atomic absorption spectrophotometry. Results: The contents of amino acids in the three strains of YTH-001, YTH-002 and YTH-003 were similar. The contents of amino acids in strain JYH-001 and SYH-001 were lower than other strains; The differences in the content of Zn, Fe and Sn are closely related to the phylogenetic relationship among them. YTH-001, YTH-002 and YTH-003 are three varieties of ‘Yatehong', and their affinities are relatively close. Conclusion: TheLonicera japonica Thunb fruit of strain ‘Ya Te Hong' was rich in Zn and Fe, which had high value for development.
