Six new sesquiterpenoids, named as ainslides A−F (1–6), including one carotene‐type sesquiterpene (1), one eudesmane (2), four guaianolides (3–6), together with eight known sesquiterpenoids (7–14), were purified from the whole plants of Ainsliaea pertyoides. The structures of these sesquiterpenoids were characterized based on spectroscopic methods including 1D and 2D NMR, HR‐ESI‐MS, UV, and IR spectra,...
Four new diterpenoids, rubellawus A–D (1–4), along with three known compounds, were isolated and identified from the flowers of Callicarpa rubella. Their structures were elucidated by various spectroscopic analysis. All the compounds were screened for their anti‐inflammatory activity and 14α‐hydroxyisopimaric acid and isopimaric acid showed significant NLRP3 inflammasome inhibitory activity with IC...
