Abstract Two new iridoids, 3-(5-(methoxycarbonyl)-2-oxo-2H-pyran-3-yl)butanoic acid, named verbeofflin I (1), and 7-hydroxydehydrohastatoside (2), were isolated from the aerial part of Verbena officinalis L, along with three known iridoids, verbenalin (3), 3,4-dihydroverbenalin (4), hastatoside (5) by means of various column chromatography steps. The structures of these compounds were elucidated through analysis of their spectroscopic data obtained using 1D and 2D NMR and MS techniques. Verbeofflin I (1) is the new class of secoiridoid in the family Verbenaceae.
