红花岩黄芪化学成分研究

目的：对红花岩黄芪化学成分进行研究。方法：用溶剂法、色谱法提取、分离红花岩黄芪化学成分，用波谱法鉴定其结构。结果：从红花岩黄芪中分离得到7个化合物，碳三十醇（1），二十四碳酸（2），5,7-二羟基-4′-甲氧基-6,8-二异戊烯基异黄酮（ 3），对香豆酸二十二酯（4），豆甾醇（5）, 5,7-二羟基-4，-甲氧基- 6-异戊烯基异黄酮（6），咖啡酸二十四酯（7）。结论：化合物3和4为新天然产物，其它化合物均为首次从该植物中获得。

Studies on chemical constituents of hedysarum multijugum

Objective: To study the chemical co nstituents obtained from Hedysarum multijugum . Methods: The compounds were separated by liquid-liquid extraction a nd chromatography, their structures were identified by spectral analyses. Results: Seven compou nds were obtained triacontyl alcohol (1); tetra cosanoic acid (2); 5,7-dihydro xy-6, 8-di-C-prenyl -4′-methoxy -isoflavone (3); 4′-hydroxy-trans-cinnamic acid docosyl ester (4); stigmasterol (5); 5, 7-dihydroxy-6-C-prenyl-4′-methoxy-isofl avone (6, Gancaonin M); caffeic acid tetracosyl ester (7). Conclusion: Compounds 3 and 4 were new natural compoun ds and the rest were obtained from the plant for the first time.
