A new compound, named gentianopfluorenone (1), along with three known compounds,1-O-β-d-glucopyranosyl-5-hydroxy-3-methoxyxanthone (2), 1-O-[β-d-xylopyranosyl-(1 → 6)-β-d-glucopyranosyl]-7,8-dihydroxy-3-methoxyxanthone (3), and apigenin (4), were isolated from the whole herb of Gentianopsis paludosa. On the basis of spectral and chemical evidence, the structure of 1 was elucidated as 4,4a,6-trihydroxy-5-methoxy-fluoren-2,9-dione. Compounds 2-4 were isolated from the plant for the first time.
