Abstract

From the aerial parts of Lagotis stolonifera (Scrophulariaccae), a new phenylpropanoid glycoside, lagotoside (8), and the three known glycosides ehrenoside (5), verbascoside (= acteoside; 6), and plantamajoside (7) were isolated, together with the four known iridoid glucosides aucubin (1), catalpol(2), globularin (4), and lythantosalin (3). The structure of the new compound 8 was elucidated on the basis of chemical and spectral data as 2‐(3‐hy‐droxy‐4‐methoxyphenyl)ethyl O‐[α‐L‐arabinopyranosyl‐(1 → 2)]‐O‐[α‐L‐rhamnopyranosyl‐(1 → 3)]‐4‐O‐feruloyl‐β‐D‐glucopyranoside.
