黄毛楤木化学成分的研究

Study on the Chemical Composition of Aralla Decaisneana Hance

目的:为开发利用江西丰富的黄毛楤木资源提供科学依据。方法:采用火焰及石墨无焰原子吸收光谱法测定微量元素的含量;用氨基酸分析仪测定氨基酸含量;柱层析法分离测定楤木总苷含量;用大孔吸附树脂法分离皂苷,光谱分析鉴定其结构。结果:确定了楤木中微量元素、氨基酸、楤木皂苷的种类及含量。结论:楤木中微量元素、氨基酸含量丰富;皂苷含量随季节而变化;分离得到4个皂苷单体,其中两个为新化合物。

Objective:To supply the scientific basis for developing and utilizing the plentiful Aralla decaisneana Hance. Method:Determining the content of trace element by flame or graphite flameless atomic absorption spectrometry;Determining the content of amino acid by the analytical instrument of amino acid;Determining the content of total saponin by column chromatography. Parting saponins by macro-reticular resins;Identifing its structure by spectrum analysis. Results:The kinds and contents of the trace element,of amino acid,and saponinsin Aralla decaisneana Hance were determined. Conclusion:There is plentiful trace element and amino acid in Aralla decaisneana Hanuce, the content of saponins changes along with the season s changing. Two new compounds were found out of the four saponins.
