Studies on Chemical Constituents of Maackia amurensis Rupr. et. Maxim.

目的 :对怀槐心材乙醇提取物的乙酸乙酯萃取部分进行化学成分的研究。方法 :硅胶柱色谱和SephadexLH 2 0凝胶色谱分离纯化 ;UV ,IR ,MS ,1HNMR ,13 CNMR(DEPT)和 2DNMR鉴定化合物的结构。结果 :分离并鉴定了 4′ ,8 二羟基 7 甲氧基异黄酮 (Ⅰ )、鸢尾种苷元 (Ⅱ )、黄豆黄素 (Ⅲ )和白藜芦醇 (Ⅳ )。结论 :Ⅰ为新的异黄酮类化合物 。

Objective:To study the chemical constituents of EtOH extract from heartwood of Maackia amurensis .Method:Silica gel column chromatography and Sephadex LH 20 were employed to separate, and the compounds obtainedere elucidated by means of UV ,IR,MS, 1H NMR, 13 C NMR.Result:4′,8 dihydroxyl 7 methoxylisoflavone (Ⅰ),tectorigenin(Ⅱ),glycitein(Ⅲ) and resveratrol (Ⅳ) were isolated and identified.Conclusion:Among them, Compound Ⅰ was a new isoflavone and compound Ⅲ was obtained from M. amurensis for the first time.
