Two new secoiridoid glycosides from Verbena officinalis

Abstract

Two new secoiridoid glycosides, verbenoside A (1) and verbenoside B (2), have been isolated from the ethanol extract of the aerial parts of Verbena officinalis L. Their structures were elucidated on the basis of spectroscopic evidences, especially 1D, 2D NMR, and MS experiments.
