Abstract From the roots of Swertia iberica, together with the previously known swertiaperennin decussatin, gentiakochianin, and norswertianin, we have isolated two new xanthones—isogentiakochianin and swertiaiberin. On the basis of UV, IR, PMR, and mass spectroscopy, the structure of 1, 3, 8-trihydroxy-7-methoxyxanthone is proposed for isogentiakochianin, and that of 1, 2, 3-trihydroxy-7, 8-dimethoxyanthone for swertiaiberin.
