银合欢种子化学成分预实验

Preliminary Tests for Chemical Components of Leucaena leucocephala(Lam.) de Wit Seeds

目的采用系统预试法对银合欢种子可能的化学成分进行预实验,初步探索银合欢种子的化学成分。方法采用试管反应法,对银合欢种子的石油醚、水、95%乙醇提取物进行研究,通过多种指示剂和显色剂的沉淀反应或颜色反应,对银合欢种子可能含有的化学成分进行初步研究。结果银合欢种子中可能含有氨基酸、糖、有机酸、皂苷、黄酮类、酚类、强心苷、生物碱和挥发油等化学成分。结论初步确定银合欢种子含有多种有效成分,为银合欢种子的进一步开发利用提供了实验基础。

Objective To identify the chemical components of Leucaena leucocephala（ Lam. ） de Wit seeds using comprehensive preliminary tests. Methods The mixture was extracted from Leucaena leucocephala（ Lam. ） de Wit seeds with petrol ether, purified water and 95% ethanol was studied using test tube method. The chemical components of Leucaena leucocephala （Lam.） de Wit seeds were preliminarily demonstrated using precipitation reaction and color reaction of multiple indicators. Results Leucaena leu- cocephala （ Lam. ） de Wit seeds might contain amino acids, sugar, organic acid, sapaomins, flavonoids, phenol, cardiac glycosides, alkaloids and volatile oil. Conclusion The research provides foundation for further study and application of Leucaena leucocephala （Lain.） de Wit seeds.
