Their structures were elucidated unambiguously by spectroscopic methods such as 1D and 2D NMR as well as HRESIMS. The anti-inflammatory and analgesic activities of the isolated compounds were also evaluated in vitro. Among the tested compounds, 1, 2, and 4 showed potent anti-inflammatory activity through both nitrite and IL-6 pathways at 200 μM. Besides, compound 1 exhibited the highest decrease in PGE2 level, with a higher inhibition rate compared to positive control indomethacin.
