Abstract
A new dimeric secoiridoids derivative, named japonicaside E, together with six known compounds were isolated from the flower buds of Lonicera japonica. The structures of these compounds were elucidated by the analyses of mass spectrometry and NMR spectroscopy. All compounds were evaluated for anti-inflammatory activity in vitro.
