SummaryFrom the epigeal part ofInula britannica L. a new sesquiterpene lactone has been obtained — britannin, with the composition C19H26O7, mp 192–194°C (from ethanol). [α]D20–26° (c 5.0; chloroform). Structure (I) has been proposed for it.

Cytotoxic activity of sesquiterpene lactones from Inula britannica on human cancer cell lines
TLDR
Five new sesquiterpene lactones were isolated from Inula britannica collected in the wild from Serbia along with five known compounds and showed similar cytotoxic activity toward drug sensitive and drug resistant cancer cell lines. Expand
Anti-proliferative Activity and Apoptotic Potential of Britannin, a Sesquiterpene Lactone from Inula aucheriana
TLDR
Inula aucheriana n-hexane, CHCl3 and MeOH extracts were evaluated for their anti-proliferative activity against HepG-2, MCF-7, MDBK and A-549 cells and the apoptotic inducing properties of britannin were evaluated on human breast adenocarcinoma cells through the terminal deoxynucleotidyl transferase dUTP nick end labeling (TUNEL) assay.
