 note = {Seven new dihydrobenzofurans and 2 new propynyl thiophenes were isolated from the roots of Eupatorium heterophyllum together with 13 known compounds. The compounds were characterized using spectroscopic methods including 2D NMR, infrared, and mass spectrometric techniques. Aerial parts of this plant have been known to contain various sesquiterpenoids and displayed high chemical diversity (several compounds isolated and/or identified) among their chemical constituents depending on the collection site. Nevertheless, we found that the chemical diversity in the roots was lower than in the aerial parts., Natural Product Communications, 17(1), doi: 10.1177/1934578X211072331; 2022},
