A New Secoiridoid Glycoside from Helwingia chinensis (Cornaceae)

A new secoiridoid glycoside,together with tree secoiridoid glycosides were isolated from the AcOEt fraction of the aerial part of Helwingia chinensis.Their structures were elucidated to be 10-O-trans-cinnamoyl oleoside (1),10-hydroxyoleoside 11-methyl ester (2),jasminoside (3) and 10-hydroxyoleuropein (4) by detailed spectroscopic analysis.
