Two novel flavonoid glycosides, 6"'-dihydrophaseoylspinosin (1) and 6″,6"'-diferuloylspinosin (2), were isolated from the MeOH extract of Semen Ziziphi Spinosae, together with six known flavonoids, isovitexin-2″-O-β-(6-O-E-feruloyl)glucopyranoside (3), spinosin (4), isospinosin (5), 6"'-feruloylspinosin (6), swertisin (7), and isovitexin-2″-O-β-d-glucopyranoside (8). The structures of 1 and 2 were elucidated by spectroscopic methods including UV, IR, ESI-TOF-MS, 1D NMR, and 2D NMR experiments.
从酸枣仁的甲醇提取物中分离出两种新型黄酮苷，6"'-二氢菜豆酰斯皮诺素（1）和6″,6"'-二阿魏酰斯皮诺素（2），以及六种已知黄酮类化合物，异荭草素-2″-O-β-(6-O-E-阿魏酰)吡喃葡萄糖苷（3）、斯皮诺素（4）、异斯皮诺素（5）、6"'-阿魏酰斯皮诺素（6）、獐牙菜苷（7）和异荭草素-2″-O-β-D-吡喃葡萄糖苷（8）。通过紫外光谱（UV）、红外光谱（IR）、电喷雾电离飞行时间质谱（ESI-TOF-MS）、一维核磁共振（1D NMR）和二维核磁共振（2D NMR）等光谱方法阐明了1和2的结构。
