Their structures were established by the basis of comprehensive spectroscopic data analysis and X‐ray crystallographic diffraction. Both 1 and 2 significantly inhibited the secretion of pro‐inflammatory cytokines IL‐6, TNF‐α, and IL‐1β, suggesting that these two natural 2,3‐dihydro‐1H‐indene derivatives may be active components of S.?involucrata and may block inflammation in the initial stage. 收起
