new megastigmane glycoside, auricuomegastigmane I (7), were isolated from the seeds of Cassia auriculata, together with 11 known constituents. The chemical structures of seven new constituents were characterized on the basis of chemical and physicochemical evidence. In the present study, auricuosides I (1)–V (5) were obtained from the seeds of C. auriculata. To the best of our knowledge, there is no
五个新的二萜糖苷,金耳苷I(1),II(2),III(3),IV(4)和V(5),新的黄酮糖苷,金黄酮苷I(6)和新的大麦角酚糖苷,金葡糖苷我(7)是从决明子的种子中分离出来的,包括11种已知成分。根据化学和物理化学证据对七个新成分的化学结构进行了表征。在本研究中,Auricuosides I(1)–V(5)是从C. auriculata的种子中获得的。。据我们所知,尚无关于从植物中分离具有14位羟基的金脲内酯的报道。从化学分类学和金脲内酯的生物合成的角度来看,该发现是有趣的。
