Two new compounds, a xanthonoid and a flavonoid C-glycoside, were isolated from the ethyl acetate extract of the dried herb of Comastoma pedunlulatum. The structures of the new compounds were elucidated, respectively, as 1,8-dihydroxy-3,5-dimethoxyxanthone 1-O-[2-(4′-hydroxy-3′,5′-dimethoxy-E-cinnamoyl)]-β-d-xylopyranosyl-(1-6)-β-d-glucopyranoside (1) and 6″-O-acetylisoorientin (2) on the basis of their spectroscopic and physicochemical properties.
