Six new secoiridoids, syrretosides E-J (1-6) and four known secoiridoids (7-10), were isolated from the stem barks of Syringa reticulata. Their structures were established by the 1D and 2D NMR spectra, HR-ESI-MS, and comparison with the literature. The cytotoxicity of the isolated monomeric compounds against RAW264.7 cells was investigated by the CCK8 assay, and the results showed that the individual compounds were not cytotoxic to RAW264.7. The anti-inflammatory activity of these compounds was evaluated using the LPS-induced RAW264.7 inflammatory cell model and the results showed that compounds 3-7 and 9 showed varying degrees of anti-inflammatory activity.
