Securidacaxanthone A, a heptaoxygenated xanthone from Securidaca longepedunculata

From the root bark of Securidaca longepedunculata, a heptaoxygenated xanthone ( 1) has been isolated as well as two known xanthones ( 2) and ( 3) and two salicylic acid derivatives ( 4) and ( 5). The structure of 1 has been elucidated from 1H and 13C-NMR spectral data.
