Abstract: | One new norsesquiterpenoid, namely tussfarfarin A (1), and four new artifacts resulting from extraction procedure, namely tussfarfarin B (2), 6-(1-ethoxyethyl)-2,2-dimethylchroman-4-ol (3), 5-ethoxymethyl-1H-pyrrole-2-carbaldehyde (4), and 3β-hydroxy-7α-ethoxy-24β-ethylcholest-5-ene (5), along with 18 known compounds, were isolated from the flower buds of Tussilago farfara. Their structures were elucidated by extensive spectroscopic analysis. |
