Secoiridoid glycosides from the leaves of Hydrangea macrophylla subsp. serrata

摘要

Seven secoiridoid glycosides, secologanin dimethyl acetal (1), ra-butyl vogeloside (2), n-butyl epi-vogeloside (3), (7R)-n-butyl morroniside (4), hydrangenoside A (5), hydrangenoside C (6), and hydrangenoside A dimethyl acetal (7), have been isolated from the leaves of Hydrangea macrophylla subsp. serrata (Thunb.) Makino (Saxifragaceae). The structures were elucidated on the basis of spectral data.
