This study isolated and characterized five new secoiridoid glycosides from the fruits of Cornus officinalis. One of these compounds showed a neuroprotective effect against H2O2-induced cell damage in preliminary assays.
Five new secoiridoid glycosides, cornusphenosides E-I (1-5), were isolated and characterized from an active fraction of ethanol extract of the fruits ofCornus officinalis. Their structures were determined by extensive spectroscopic data analysis, including 2 D NMR and HRESIMS experiments. In the preliminary assay, compound5(when evaluated at 10 mu M) showed the neuroprotective effect against H2O2-induced SH-SY5Y cell damage.
