Abstract:
A new benzyl triglycoside, benzyl O-α-l-rhamnopyranosyl-(1→2)-[β-d-glucopyranosyl-(1→3)]-β-d-glucopyranoside (1) together with two diastereomer phenylethanoid glycosides, (7R) and (7S)-campneoside I (10, 11) were isolated from the leaves of Magnolia sirindhorniae in addition to 20 known compounds. The structure elucidation of these compounds was based on analyses of physical and spectroscopic data including 1D and 2D NMR experiments.
