Abstract

A new phenylpropanoid glycoside, martynoside (1), was isolated from the leaves and stems of Martynia louisiana MILL. (syn. Proboscidea Jussieui STEUD.) (Martyniaceae) together with acteoside (2), roseoside (3), cornoside (4), ajugol (5) and mioporoside (6). The structure of martynoside was elucidated to be 1 by chemical and spectral evidence. The isolation of catalpol (7) and cornoside (4) from the fresh unripe fruits was also described.
