Examination of the ether extract of the roots of Boerhaavia diffusa L. led to the isolation of three new rotenoid analogues along with fatty acids, glycerides, and sterol derivatives. The structures of two rotenoid analogues named boeravinone A and boeravinone B have been determined by means of nuclear magnetic resonance spectroscopy including two-dimensional incredible natural abundance double quantum transfer experiment (2D INADEQUATE) and 1H-13C long range correlation spectroscopy.
对白花蛇舌草根的乙醚提取物的检查导致分离出三种新的鱼藤素类似物以及脂肪酸、甘油酯和甾醇衍生物。两种鱼藤素类似物 boeravinone A 和 boeravinone B 的结构已通过核磁共振光谱法确定,包括二维令人难以置信的自然丰度双量子转移实验(2D INADEQUATE)和 1H-13C 长程相关光谱。
