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.Entities:
