 note = {The chemical constituents in the roots of 3 Cremanthodium campanulatum Diels(Asteraceae) samples collected in Yunnan and Sichuan Provinces, China, were chemically investigated. A total of 8 bisabolane-type sesquiterpenoids, 2 of which were new, and a
new oplopane-type sesquiterpenoid, along with a new lignan were isolated and their structures elucidated based on spectroscopic
analyses. This is the first report on the chemical study of C. campanulatum., Natural Product Communications, 14(7), doi: 10.1177/1934578X19863582; 2019},
