Abstract
Abstract The new flavonoid glycoside stachyspinoside (1), and the three iridoids, 7-O-acetyl-8-epi-loganic acid (2), ajugol (3) and harpagide (4) were isolated from Stachys spinosa. The structures of these compounds were established on the basis of mass spectrometry (ESMS and tandem MS), one-and two-dimensional nuclear magnetic resonance experiments (COSY, COSY LR, HMQC, TOCSY and HMBC) as well as simple chemical derivatization.
摘要从棘豆中分离得到新的类黄酮苷stachyspinoside(1)和环烯醚萜类化合物7- o -乙酰-8-表马甘酸(2)、阿胶苷(3)和哈弗苷(4)。通过质谱(ESMS)、串联质谱(MS)、一维和二维核磁共振实验(COSY、COSY LR、HMQC、TOCSY和HMBC)以及简单的化学衍生，确定了这些化合物的结构。
