Anti-inflammatory sesquiterpene dimers and diterpenes from the aerial part of .

Phytochemical investigation on the 95% alcohol extract of the aerial part of led to the isolation of three new compounds, inulanolides F-G () and 17-carboxaldehyde-ent-kaur-18-oic acid (), together with four known compounds (). The structures of new compounds were elucidated by using spectroscopic data. Most of the isolated compounds showed significant anti-inflammatory activities.
